Editor’s Comment<br />




COVER PIC:<br />



Welcome to the launch issue of <strong>Total</strong> <strong>Contractor</strong>, an exciting, new,<br />

monthly magazine exclusively for contractors who operate in the<br />

roofing, cladding and insulation markets.<br />

In what has been a turbulent couple of years for these markets and the<br />

wider construction sector in general, now, more than ever, it’s important<br />

to not only debate the issues, share opinions and take note of the<br />

seemingly constant updates to regulations and technology – which of<br />

course we will do in the pages of <strong>Total</strong> <strong>Contractor</strong> – but also shine a light<br />

on the quality work and impressive projects which contractors carry out<br />

every day. Whether they are small residential roof refurbs, or large<br />

commercial developments, <strong>Total</strong> <strong>Contractor</strong> will focus on the role of the<br />

contractor and their work in completing these projects.<br />

Above: Truro-based roofer Tom Knight, who was Highly Commended in<br />

Redland’s Apprentice of the Year competition 2017, pictured working on site<br />




Everyone likes a bit of advice from time to time – not that we always take<br />

it onboard! – but at <strong>Total</strong> <strong>Contractor</strong> we’ll be bringing you regular top tips<br />

for best practice both in the office and on site. In this issue, for example,<br />

we take a look at what contractors need to consider if they’re thinking of<br />

adding a drone to their tool-kit – and there’s a lot more to it than you<br />

might think! (p.14); we also hear how smartphone use on site might be<br />

more dangerous than you think (p.18); plus, we take a look at some of the<br />

options contractors can take to reduce their van insurance costs (p.78).<br />

So read on for all this and so much more including how the new dry-fix<br />

Standard BS 6812 might impact you (p.20); plus we hear one<br />

contractor’s strong views on the growing gulf between justified and<br />

unjustified material price rises (p.82).<br />

Industry News<br />


With the fallout from the collapse of<br />

Carillion still having a huge impact on the<br />

construction sector supply chain, question<br />

marks remain over the fate of 43,000 jobs,<br />

whilst 30,000+ small businesses are<br />

thought to be owed money.<br />


Vivalda Group, a leading distributor of<br />

cladding systems, has called for greater<br />

clarity on rainscreen cladding Standards and<br />

confirmed that it no longer promotes<br />

aluminium composite materials (ACM) for use<br />

on high-rise applications which fail to reach<br />

A2 Standard.<br />

Ben Jayes, Managing Director of Vivalda Group<br />

So how can SMEs protect themselves against<br />

such collapses? ArchOver CEO Angus Dent<br />

offers his advice: “Overall, 25% of<br />

bankruptcies are due to unpaid invoices. In<br />

the construction industry, this figure is likely<br />

to be even higher. This is a sector that<br />

experiences the highest levels of insolvency<br />

per year so SMEs need to be more mindful of<br />

the risks they are exposed to.<br />

“Don’t just rely on a big company’s<br />

reputation for reassurance. Look at whether<br />

they have a good record of paying their debts.<br />

Do they have a strong cashflow? Have your<br />

peers had issues with invoicing them?<br />

Consider what would happen if a customer<br />

were to default and ensure that you have<br />

protection, such as credit insurance, in place.<br />

The Carillion case shows that credit insurance<br />

does pay off when a big contractor goes bust<br />

– the payments to its suppliers will range<br />

from £5,000 to several million pounds – but<br />

not nearly enough companies took it out.<br />

The company is concerned that contractors could<br />

inadvertently make unintentional specification<br />

errors, given the complexity of the UK's current<br />

safety standards.<br />

While the initial report on the likely causes of the<br />

Grenfell fire is not expected until spring 2018,<br />

Vivalda Group has stated that shortcomings in<br />

the current ‘approved inspector’ regime have<br />

created a confusing landscape for contractors.<br />

This scenario has been made worse, according to<br />

Vivalda, by the widespread adoption of complex<br />

laboratory tests used by manufacturers to gain<br />

approval for ‘so-called’ safe systems which are<br />

impossible to replicate on site.<br />

Ben Jayes, managing director of Vivalda Group,<br />

explained: “The issue of fire safety is at the very<br />

top of the agenda for contractors right now, but<br />

many within the industry are not helping to build<br />

confidence in the supply chain. We know of one<br />

manufacturer of ACM that put out ambiguous<br />

claims relating to how their standard material<br />

performs at a high level. But that’s not the whole<br />

story. It’s worth remembering that behind every<br />

panel lies a complex web of subframes, fixings<br />

and fire barriers, none of which this manufacturer<br />

is prepared to detail as part of a system.<br />

“The poor contractor is on the hook should there<br />

be failure in even one minor component, so<br />

confidence in the complete system’s performance<br />

is vital. Besides, setting up a rig for a lab test is<br />

one thing, replicating it on site, 18 metres in the<br />

air, is quite another.<br />

“We’ve looked closely into this and decided in the<br />

best interest of clarity to promote only ACM<br />

products that meet or exceed the gold standard of<br />

A2. Despite their best endeavours, many<br />

customers could be installing systems that may<br />

turn out not to be safe. Thus, we’ve moved to<br />

make the task of A2-standard aluminium<br />

rainscreen cladding simple – by offering only fully<br />

approved claddings and associated fixings.”<br />

What will Hackitt Review mean for contractors? p.62<br />

“When we trust too much in a company’s<br />

longevity or size, we’re making an<br />

understandable but risky mistake.<br />

Investments and contracts can go bad but<br />

that doesn’t mean you can’t take steps to<br />

protect yourself. Just like Carillion didn’t have<br />

to accept tough contracts, SMEs should not<br />

accept contracts where there’s a risk that they<br />

won’t be paid or where there aren’t measures<br />

in place to protect them against losses.<br />

“Do your research, go only with sound<br />

debtors and put protection for your deals in<br />

place.” Payment issues, a contractor’s view: p.76<br />

Industry News<br />


Housebuilders are reportedly investing in<br />

modern methods of construction and<br />

skills to address a number of industry<br />

challenges as they look to deliver growth<br />

and new homes for the future, according<br />

to new research from Lloyds Bank<br />

Commercial Banking.<br />

The report, which surveys housebuilders and<br />

their supply chain, analyses the state of the<br />

industry today and the opportunities and<br />

challenges it faces in the future.<br />

The sector is said to be adopting modern<br />

methods of construction that hold the<br />

potential to boost productivity and supply.<br />

Firms reported that they are already investing<br />

in new building techniques, including<br />

modular housing (68%) and panelised<br />

systems (56%).<br />

Housebuilders’ motivations to adopt these<br />

methods include improved efficiency, ease of<br />

build, better construction standards and in<br />

some areas increased margins.<br />

An ongoing shortage of skilled workers<br />

continues to affect the sector with a third<br />

(31%) of firms saying there is a skills<br />

shortage at a national level. More than a<br />

quarter (29%) said they have trouble<br />

recruiting skilled workers in the regions<br />

where they operate.<br />

The report also found that the UK’s exit from<br />

the EU was exacerbating the skills shortage,<br />

with half (50%) stating that it was making<br />

recruitment harder for specific roles, while a<br />

quarter (26%) said that access to EU labour<br />

is a key challenge for their business.<br />

On a positive note, the report found a sector<br />

tackling the skills shortage head on, as almost<br />

seven in ten firms (69%) of respondents are<br />

investing in staff training, and half (51%) are<br />

setting up apprenticeship programmes.<br />


As part of the Government’s Each Home<br />

Counts recommendations, BSI has been<br />

appointed by the Department of Business,<br />

Energy and Industrial Strategy (BEIS) to<br />

review and revise the existing PAS 2030: 2017,<br />

the specification for the installation of energy<br />

efficiency measures in existing buildings, and<br />

develop a new PAS 2035.<br />

With this in mind, the National Insulation<br />

Association (NIA) attended a British Standards<br />

Institution (BSI) high level workshop in January<br />

2018 which briefed key organisations on the work<br />

involved in developing new quality standards for<br />

the energy efficiency industry.<br />

Neil Marshall, Chief Executive of the NIA,<br />

commented: “This work is extremely important as<br />

it will clearly set out the specifications and<br />

Standards that will apply to the installation of<br />

insulation measures. The existing PAS 2030 is a<br />

little complicated and there are some aspects that<br />

are open to interpretation, however, this project<br />

provides the opportunity to simplify matters and<br />

remove any ambiguity ensuring that all installers<br />

will install to a common, uniform standard.<br />

New research from Which? Trusted Traders has<br />

highlighted the difficulty that members of the<br />

public have in finding and hiring tradespeople,<br />

with roofers proving particularly elusive.<br />

The study, which was carried out on more than<br />

1,000 people found that one in four (25%) had<br />

difficulty finding a roofer, with builders (22%) and<br />

bathroom fitters (20%) coming in closely behind.<br />

“The NIA will be represented on the PAS 2030<br />

and PAS 2035 Steering Groups and the<br />

Measures Experts Groups and the intention is<br />

for these new specifications to be introduced in<br />

October 2018 alongside the new Energy<br />

Company Obligation (ECO) and Each Home<br />

Counts Quality Mark.<br />

“At the NIA we are very supportive of Each Home<br />

Counts as it provides a vehicle to ensure quality<br />

installations are delivered on a constant basis<br />

and instil confidence in policy makers, specifiers<br />

and householders. In addition to contributing to<br />

the development of the new specifications, we<br />

will be ensuring that our members are kept up to<br />

date and provide advice and guidance to help<br />

them comply with the new Standards.<br />

Furthermore, we are also working with the British<br />

Electrical Allied Manufacturers Association<br />

(BEEMA) which will clearly set out minimum<br />

ventilation requirements when installing<br />

insulation. We are also advising the Scottish<br />

Government on the new quality framework they<br />

are currently developing for Government funded<br />

schemes.”<br />


In contrast, mechanics were the easiest<br />

tradespeople to find, with almost all of those<br />

surveyed who needed to hire a mechanic (97%)<br />

explaining that it was easy to do so.<br />

Heating engineers (93%) and electricians (88%)<br />

were also among the easiest traders to find.<br />

Raj Kakar-Clayton, MD of Which? Trusted Traders<br />

stated that: “Consumers shouldn’t have to<br />

struggle when trying to track down a local,<br />

reliable tradesperson,” and advised members of<br />

the public to “work with someone who has an<br />

excellent reputation and who has been vetted by<br />

an independent endorsement scheme.”<br />

New research by the Federation of Master<br />

Builders (FMB) claims the UK economy is<br />

missing out on £10bn each year because<br />

homeowners are so fearful of hiring a<br />

cowboy, they simply don’t commission<br />

building work.<br />

Key findings from the FMB’s research into<br />

consumer confidence in the UK’s builders<br />

include:<br />

• Anxiety over cowboy builders is causing the<br />

UK to miss out on £10bn of activity each year.<br />

• One third (32%) of homeowners are put off<br />

doing major home improvement works<br />

requiring a builder because they fear hiring a<br />

dodgy builder.<br />

• If all homeowners had full confidence in the<br />

building industry, they would typically spend<br />

on average £40,000 on major home<br />

improvement projects over the next five years.<br />

Brian Berry, Chief Executive of the FMB,<br />

explained: “A third of homeowners are so<br />

anxious about the possibility of choosing a<br />

builder, they don’t commission any building<br />

work whatsoever. This means that the UK<br />

economy could be missing out on £10bn of<br />

activity every year. Indeed, the FMB’s latest<br />

survey shows that on average, your typical<br />

homeowner would spend £40,000 on major<br />

home improvement projects over the next five<br />

years if they could be guaranteed a positive<br />

experience. We need to end the cowboy<br />

builders’ reign of terror so we can give all<br />

homeowners the confidence they need to<br />

invest their cash in building work. The<br />

Government should consider introducing<br />

some form of mandatory licensing system<br />

for domestic builders so that consumers<br />

know that all building firms have a base<br />

level of skill, competence and<br />

professionalism.”<br />


The team at the BMI National Training Centre<br />

(NTC) have announced that an already<br />

successful year in 2017 continued right into<br />

Christmas week with the launch of the first<br />

Roofing Tutor day.<br />

This day brought together tutors from a number of<br />

the colleges Redland supports with training<br />

materials across the country, alongside industry<br />

representatives from CITB and the NFRC, to<br />

discuss best educational practice and standards<br />

for their learners.<br />

Mat Woodyatt and Alastair Blant of the BMI NTC<br />

hosted a dozen representatives from key colleges<br />

Redland supports, alongside Simon Dixon of the<br />

NFRC who gave an update on the NFRC’s role in<br />

the pitched roofing sector both during 2017, as<br />

well as its plans for this year. Simon stressed that<br />

some of the most interesting news going forward<br />

is the Government’s plans to develop a new<br />

Technical – or T Level – to encourage school<br />

leavers to enter the construction industry.<br />

The team at BMI NTC explained that the launch of<br />

the Roofing Tutor Day marks yet further support<br />

Following the collapse of Carillion, Findley<br />

Roofing & Building says it has made it its<br />

mission to help as many of Carillion’s North<br />

East-based apprentices as possible.<br />

The roofing company explained that hundreads of<br />

16-18-year olds have been unable to finish their<br />

apprenticeships following the collapse of Carillion<br />

and have been left without answers.<br />

A spokesperson for Findley explained: “We want<br />

to offer a helping hand to those affected by<br />

providing them with a place on The Findley<br />

Academy, our apprenticeship training scheme.<br />

“We currently have a partnership with TyneMet<br />

College and South Tyneside College, enabling us<br />

to offer the very best training to our apprentices.<br />

Redland’s Roofing Tutor Day with Mat Woodyatt (front left),<br />

Alastair Blant (front right) and Simon Dixon (top right)<br />

for the roofing industry from the BMI Group,<br />

following on from the Redland Apprentice of the<br />

Year Award (APOTY) – which has grown to include<br />

Icopal’s product offering for a Flat Roofing APOTY –<br />

and the Group’s on-going student support network<br />

helping “invigorate and bolster education and<br />

training” in the pitched and flat roofing sectors.”<br />

The decision has been taken to meet every six<br />

months, with the next meeting due to take place<br />

at the Apprentice of the Year competition which<br />

will be held at the NTC in June 2018.<br />

Look out for further updates on the Redland’s<br />

APOTY competitions in future issues of <strong>Total</strong><br />

“We have recently relocated to new headquarters<br />

in Hartlepool, and here we have designed a brand<br />

new training centre to ensure our apprentices<br />

receive the very best Findley Roofing can offer. We<br />

believe our academy offers the perfect route into a<br />

career in roofing and building.”<br />

The spokesperson concluded: “Any Carillion<br />

apprentices who have been prevented from<br />

completing their training will not need to start<br />

their training again. With Findley you can develop<br />

the skills you have already learnt. If you are<br />

someone who can thrive in a dynamic<br />

environment, we want to hear from you.”<br />

L-r: John Mairs and Keith Moore of Bracknell Roofing<br />

A new site in Chorley, Lancashire, has<br />

taken Bracknell Roofing’s number of<br />

branches throughout the UK to nine.<br />

The company identified Lancashire as a<br />

“hotspot” for both new housing<br />

developments and commercial projects, and<br />

says it has already quoted for a raft of new<br />

tenders and projects.<br />

Keith Moore, Branch Manager, heads up the<br />

new Lancashire branch, along with newly<br />

appointed Contracts Manager John Mairs.<br />

Keith explained: “From my time at the northwest<br />

branch in Warrington, we knew that<br />

there were plenty of opportunities right<br />

across Lancashire but didn’t have the<br />

capacity to develop them, so the<br />

management team at Bracknell Roofing<br />

looked at the feasibility of opening a<br />

dedicated branch. The name and size of<br />

Bracknell Roofing has really helped to open<br />

doors for us in Lancashire, especially with<br />

developers that we haven’t worked with<br />

before.”<br />

Simon Smith, Bracknell Roofing’s Divisional<br />

Director, explained: “The strategic growth of<br />

our business this year has centred on the<br />

North of England because of the scale of<br />

both housebuilding and commercial<br />

developments in the region. These are<br />

exciting times for Bracknell Roofing, and we<br />

are well positioned to support the<br />

Government’s commitment to building more<br />

houses.”<br />


A new premium contractor reward scheme<br />

has been launched by EPDM waterproofing<br />

specialist CARLISLE CM Europe (CCM Europe).<br />

The manufacturer says PLATINUM+ is a<br />

premium contractor scheme to reward and enable<br />

them to work closely with its contractors to<br />

maximise the benefits of its HERTALAN product<br />

range for flat roofs and façades.<br />

The five key advantages of PLATINUM+ for<br />

contractors are said to include an additional<br />

discount on trade prices, exclusivity on Rhinobond<br />

and made-to-measure sheets, project referrals<br />

and specification service, advanced product<br />

training and marketing. One such innovative<br />

product included in CCM Europe’s range is the<br />

Rhinobond induction fixing system, which is now<br />

offered exclusively to PLATINUM+ contractors.<br />

Duncan Kirkwood, MD of CCM Europe, said: “Over<br />

the last year we have been expanding our<br />

manufacturing capacity due to the increase in<br />

demand for EPDM membranes. As a result of this<br />

expansion, we can now benefit from production<br />

efficiencies and improved benefits for customers.”<br />

Find a Better Way, a charity set up by Sir<br />

Bobby Charlton which helps civilian<br />

landmine blast survivors, their families and<br />

communities to ‘heal and rebuild their<br />

lives’, has received £2,500 from the Liquid<br />

Roofing and Waterproofing Association<br />

(LRWA).<br />

PLATINUM+ contractor Sam Dove, of Hub<br />

Building Project Management, explained: “I would<br />

like to thank CARLISLE CM Europe’s team for the<br />

encouragement and ongoing help with our project.<br />

I, and my team, have been very impressed both<br />

with the product and the knowledge and advice<br />

given. This has been invaluable as we have a<br />

particularly awkward set of roofs to work on.”<br />

As a special introductory offer, PLATINUM+<br />

customers benefit from a £500 credit on total<br />

HERTALAN spend over £10,000 (exc. VAT) within<br />

a three month period from the date of enrolment.<br />

One of the UK’s largest suppliers of EPDM<br />

materials for flat roofing is planning to open<br />

another facility in the north of England.<br />

Flex-R says this second UK depot will primarily be<br />

a training hub where roofing contractors based in<br />

the north of England can undergo training and<br />

guidance on its range of specialist products such<br />

as RubberBond, Sure-Weld and LQD-R.<br />

Flex-R explained that the new facility will also<br />

provide space to store a full complement of the<br />

products it supplies on a next-day basis as the<br />

sole UK distributor for US-manufactured Carlisle<br />

SynTec single ply products.<br />

Duncan Winter, Trading Director, explained: “We<br />

have identified a site along the M62 corridor that<br />

will become our centre in the north of England,<br />

and plans are at an advanced stage for opening it<br />

within the next few weeks.<br />

“The new training hub is a vital part of our growth<br />

plans because we can offer training to roofing<br />

contractors across the north of England who<br />

would have previously struggled to attend training<br />

at our High Wycombe base.”<br />

Duncan continued: “We already have strong<br />

pent-up demand for our training courses for<br />

products such as RubberBond, Sure-Weld and<br />

LQD-R, which we can only supply once a<br />

roofing contractor has completed the two-stage<br />

training process. The first is at Flex-R and the<br />

second is on site, working alongside<br />

contractors.”<br />

Flex-R has already started recruiting staff for<br />

the new hub in a bid to increase the number of<br />

technical support, specification and sales team<br />

(L-R) Ben Midwinter, Duncan Winter and Danny Cole<br />

people who support roofing contractors across<br />

the UK.<br />

Duncan concluded: “The strengths, and therefore<br />

the expansion of our business, are based on great<br />

service and back-up, particularly our technical<br />

knowledge, which roofing contractors heavily rely<br />

on. Everyone in the business is really excited<br />

about what 2018 holds for Flex-R and is fully<br />

committed to driving us forward.”<br />


It’s been a strong start to the year for<br />

Wienerberger following the news the provider<br />

Paul Hodgkinson, National Accounts Director at<br />

Wienerberger, said: “Receiving this award is a<br />

fantastic recognition for everyone at<br />

Wienerberger. It was a real team effort across all<br />

areas of the business as everyone played an<br />

important role. I’m looking forward to seeing<br />

Wienerberger develop even further over the<br />

upcoming year.”<br />

The award is determined by a variety of factors<br />

including sales growth, successful new customer<br />

ranging, a strong charity partnership and more,<br />

and Wienerberger was shortlisted from over a<br />

thousand other suppliers to just 32 top<br />

performing companies, before receiving the most<br />

votes from the Travis Perkins senior management<br />

teams. It is reported that throughout 2017<br />

Wienerberger demonstrated exceptional sales<br />

Drone Technology<br />


The National Federation of Roofing <strong>Contractor</strong>s (NFRC) receives regular queries from<br />

members on safety, legislation and technical advice. In this regular feature exclusively for<br />

<strong>Total</strong> <strong>Contractor</strong>, the Association will share some of its most frequently asked questions<br />

along with the advice given. This month, Mike Wharton, Head of Business Development,<br />

answers questions on drones.<br />

Q. I’ve seen a few of my competitors have<br />

started using drones to help them with<br />

site inspection, panoramic overviews and<br />

inspection of structures at height. It seems like<br />

a good idea but I’ve no idea how to get started.<br />

Have you got any advice?<br />

A. You are absolutely right to pinpoint that in our<br />

industry, drones could be particularly useful and<br />

that this technology is already proving immensely<br />

popular for a range of activities including site<br />

inspection, planning and health and safety.<br />

But getting started is not as simple as going out<br />

and purchasing the first drone you see.<br />

And additionally, the mantra that “drones are not<br />

toys” has been repeated by The Civil Aviation<br />

Authority which writes the<br />

guidebook here.<br />

Flying for commercial use<br />

requires their permission and<br />

to get the go-ahead you will<br />

have to show you are<br />

“sufficiently competent”.<br />

So, what does this mean?<br />

“Getting started is not<br />

as simple as going out<br />

and purchasing the<br />

first drone you see”<br />

Left: Mike Wharton, Head of Business<br />

Development at the NFRC<br />

Here at the NFRC, we have<br />

entered into an exclusive<br />

partnership with The<br />

Association of Remotely Piloted<br />

Aircraft (ARPAS-UK), the<br />

professional body and trade<br />

association for the fast evolving Remotely Piloted<br />

Aircraft Systems industry, to advise our members<br />

of the latest legislation and ensure they operate<br />

drones safely.<br />

ARPAS-UK works closely with the CAA to ensure<br />

that the regulatory framework for the safe and<br />

professional operation of remotely piloted aircraft is<br />

fit for purpose and it has been working with the

Fully Graded Roofing Battens<br />

The new British Standard for the design, materials, application, installation and performance of slates,<br />

tiles, shingles and shakes is clear: roofing battens must be graded to BS 5534.<br />

This means that battens delivered to site should be graded and marked in accordance with the new<br />

standard and have supporting documentation.<br />

There’s no grey area on BS 5534, so take it as Red that roofing battens from Marley Eternit are<br />

fully compliant.<br />

Drone Technology<br />

NFRC to produce a condensed guidance<br />

document for our members.<br />

This details the key areas of law and legislation<br />

that govern the use of drone technology, as well<br />

as the training required to fly a drone and details<br />

on how to obtain a licence known as a PFCO – a<br />

permit for commercial operation.<br />

To get a PFCO, you must attend a ground school<br />

run by a Civil Aviation Authority approved<br />

National Qualified Entity (NQE). ARPAS-UK have a<br />

number of NQE members which, under agreement<br />

with NFRC, now offer exclusive discounts on<br />

training to NFRC members.<br />

Before you consider introducing drone technology<br />

to your operations, you would need a Pilot in<br />

Command (PiC) who would be responsible for<br />

flying the drone for your business.<br />

This person will need to undertake around 30<br />

hours of study and complete a ground school<br />

class to get their PFCO.<br />

Roof inspection requires a high degree of piloting<br />

ability so this should not be taken lightly.<br />

Once you have identified a PiC and he or she has<br />

had the required training, you can buy a drone.<br />

But do your homework.<br />

Drones are either a multi-rotor or a fixed wing<br />

aircraft. A fixed wing drone looks like a model<br />

aircraft but is packed with sensors to enable it to<br />

fly alone. Fixed wings are used mainly for survey,<br />

mapping and security simply because they have a<br />

longer endurance.<br />

Multi-rotor drones are by far the most popular<br />

platform flown commercially in the UK due to<br />

their ability to land and take off vertically.<br />

These drones can carry a wide variety of sensors<br />

“You would need a Pilot<br />

in Command (PiC) who<br />

would be responsible<br />

for flying the drone for<br />

your business”<br />

“Roof inspection<br />

requires a high degree<br />

of piloting ability so<br />

this should not be<br />

taken lightly”<br />

making them incredibly versatile, but flight times<br />

range from just 10-30 minutes.<br />

They are, however, are an ideal choice for roof<br />

inspection work as they can take off and operate<br />

in contained environments.<br />

Q. Clearly using a drone can add value to your<br />

business but what are the start-up costs? Is it<br />

worth the initial outlay?<br />

In many instances, using drones mitigates the<br />

risk of staff having to work at height and can<br />

mean projects are completed faster and more<br />

efficiently.<br />

ARPAS has suggested that the vast majority of<br />

NFRC members would find drones a useful addon<br />

to their existing toolkit but you are right,<br />

introducing this technology to your business costs<br />

money.<br />

This is why ARPAS entered into an exclusive<br />

partnership with NFRC to offer exclusive<br />

discounts on training to our members.<br />

Images show drones in operation. Drones offer many<br />

benefits for projects but there are a number of issues that<br />

have to be addressed before operating drones on site<br />

An average training course will cost around<br />

£1,250; a ‘starter’ package would require a<br />

training drone for around £200 and you would<br />

need a specific “platform” which could cost an<br />

additional £3,500.<br />

A day’s worth of flying may require ten sets of<br />

batteries at a cost of about £1,800.<br />

and is located in the member area of our website.<br />

Contract Talk<br />



The publication of two reports in recent weeks begs the question of whether smartphones<br />

are safe to use on site. Janine Brady, SIG Roofing’s Marketing Manager, looks at whether<br />

the fact that phones are so smart these days could actually be their undoing.<br />

Of the nine most dangerous jobs in the UK,<br />

roofing is in the top three according to<br />

Adzuna – a job search engine that used<br />

its own data along with research from the Office<br />

for National Statistics (ONS) to compile the list.<br />

When you look a bit closer at the figures<br />

for roofing, you’ll find that the data<br />

also includes scaffolding, and<br />

the report found that the<br />

majority of workplace deaths<br />

are due to falls. Falling or<br />

injuries sustained while falling<br />

accounted for 29% of all<br />

workplace deaths last year – and<br />

scaffolding is one of the most dangerous<br />

careers in the country, as 69 scaffolding-related<br />

deaths have occurred since 2010.<br />

It’s a stark reminder of what a challenging<br />

profession roofing is and why there are a raft of<br />

stringent regulations in place to keep everyone<br />

safe at work.<br />

Issued hot on the heels of the Adzuna study was<br />

a completely unrelated report by Microsoft which<br />

found that technology – such as smartphones –<br />

is becoming increasingly distracting for workers.<br />

The report stated that it’s due to the fact that<br />

we’re all constantly being bombarded by a steady<br />

stream of emails, messages and notifications<br />

from social media sites.<br />

Driven to distraction?<br />

For us in roofing, the publication of these two<br />

reports so closely together poses the question as<br />

to whether smartphones are becoming too<br />

distracting for use on site, and we wonder about<br />

the dilemma this presents to<br />

owners of roofing companies<br />

because of the duty of care to<br />

keep themselves, their<br />

employees and their subbies safe<br />

at work. On the one hand,<br />

smartphones are an<br />

absolute essential on site, as<br />

they ensure we’re all<br />

contactable. You could even<br />

venture to say that<br />

smartphones have boosted<br />

productivity because of the<br />

ability to get online when you’re<br />

onsite and access a wealth of<br />

information at your fingertips. It’s now<br />

commonplace for smartphones to be used to check<br />

the status of deliveries or to download spec sheets<br />

from manufacturers’ websites, often simply by<br />

tapping an app.<br />

Attention grabbers<br />

However, smartphones have become super-smart<br />

in mastering the ability to grab our attention. It’s<br />

like they’re slowly turning us into modern-day<br />

versions of Pavlov’s dogs because we’ve all<br />

become compelled to check our smartphones the<br />

instant they beep or buzz because of the worry of<br />

missing out. And even if we can’t respond to them<br />

straight away, they do play on our minds and we<br />

check them at the first available opportunity – and<br />

this level of distraction isn’t always helpful when<br />

we work in the third most dangerous job in the UK.<br />

While their intelligence could be their undoing, it<br />

could also be a smartphone’s saving grace – by<br />

using their functionality to dial down their ability<br />

to distract us. Here are a couple<br />

of simple tips that can be used<br />

by everyone on site.<br />

Change the frequency of<br />

notifications – the fewer notifications you<br />

receive, the less likely you are to check your<br />

smartphone. Notifications can be limited and you<br />

can also use the phone’s Do Not Disturb mode.<br />

Hide social media apps – a lot of people have<br />

social media apps on the home or front pages of<br />

their smartphones, but try putting them in folders<br />

on the last page of your phone instead. That way,<br />

you’re less likely to habitually click the Facebook<br />

or Instagram icon.<br />

Use a watch – that way, you won’t need to check<br />

your phone to see what time it is – and then be<br />

tempted to check updates.<br />

Install addiction-breaking apps – counterintuitively,<br />

you can reduce your phone use by<br />

installing apps such as Checky, which gathers<br />

data about your phone use, showing you how<br />

many times you unlock your phone in a day and<br />

logging this behaviour over time.<br />

You’d be surprised how some simple tips can play<br />

a small but important role in keeping everyone<br />

safe on site through the reduction of distractions,<br />

and we’d welcome comments on Twitter:<br />

BS 8612<br />



January 31st finally saw the launch of BS 8612, the Dry-fixed Ridge, Hip and Verge<br />

systems for Slating and Tiling Standard. The new Standard is a product specification which<br />

provides minimum performance requirements for dry-fix roofing components. But what does<br />

it mean for contractors? We asked a number of manufacturers to give their thoughts...<br />

Roofing contractors should<br />

welcome the changes<br />

that the new BS 8612<br />

Standard will bring to the<br />

market; as it will help ensure<br />

inadequate quality products are<br />

designed out of roof<br />

specifications and set a<br />

minimum performance that can<br />

be used to compare competing<br />

systems.<br />

using mortar bedded cappings.<br />

Not only that, dry fix systems are<br />

generally lightweight and<br />

straightforward to work with,<br />

equating to an easier and<br />

quicker fitting process.<br />

Installation is not dependent on<br />

getting the correct mortar mix or<br />

having to wait for dry weather.<br />

Ged Ferris, Marketing Manager, Cembrit Other benefits of using a dry fix<br />

system include reduced repair<br />

To prepare for the Standard, roofing contractors costs and fewer call backs. There are tried and<br />

should review the dry fix systems they currently tested systems backed by leading manufacturers<br />

use and where possible, use manufacturers who that can be relied upon.<br />

provide high quality roofing accessories, which<br />

meet the latest standards and can demonstrate Contact Cembrit UK<br />

long-term performance and durability. Using a<br />

www.cembrit.co.uk<br />

dry-fix system to secure ridges, hips, and verges<br />

@CembritUK<br />

is easier than the time-consuming method of<br />

Since BS 5534: 2014 – which<br />

brought about a step change in<br />

the requirements for fixing of<br />

pitched roofs both for roof tiles and<br />

ridge, hip and verges – we have seen<br />

an acceleration in the move away from<br />

traditional mortar fixing to modern dryfix.<br />

Dr Kevin Ley, Technical<br />

Manager, Redland<br />

Unfortunately, the resulting increased demand for<br />

dry-fix products and a lack of standardised<br />

performance requirements allowed products of<br />

questionable fitness for purpose to enter the<br />

market. The resulting problems meant there was a<br />

significant risk that past mistakes concerning<br />

mortar fix failures would be repeated.<br />

The publication of BS 8612, the first<br />

ever product Standard for dry-fixed<br />

ridge, hip and verge products in the UK,<br />

is therefore an essential and welcome<br />

landmark for the industry.<br />

Not only will it ensure that dry-fix design<br />

and installation standards are raised;<br />

but also that developers, contractors and building<br />

owners get the product quality and performance<br />

they deserve.<br />

Richard Bishop, Wienerberger Category Marketing Manager<br />

Wienerberger welcomes the changes that<br />

BS 8612 bring to the market; although<br />

not law it will help ensure an improved<br />

standard of products used in roof specifications.<br />

It is essential that specifiers state a compliance<br />

to the British Standard or risk a sub standard<br />

product being used.<br />

For the first time, BS 8612 sets minimum<br />

requirements for dry-fix products in a market<br />

driven by legislation and guidelines. The use of dry<br />

fix products has been increasing as a result and<br />

has seen many ‘cost engineered systems’ enter<br />

the market. It is essential that we, the chain, work<br />

together to ensure compliant systems are used.<br />

In short, by working together and complying to<br />

both BS 5534 and BS 8612 we will improve the<br />

standard of pitched roofing in the UK, and this<br />

will mean your project is delivered to the highest<br />

quality.<br />

The hi-res imagery that’s<br />

re-engineering roofing<br />

By Kay Rose FIoR National Sales Director, EagleView.<br />

If you’re a roofing professional, imagine<br />

how much easier your job would be if<br />

you had a full overview of the roof even<br />

before visiting the site.<br />

Imagine if – with just a few clicks of<br />

your mouse – you could order a full roof<br />

measurement report that includes high-resolution<br />

images and precise dimensions<br />

of all the areas. Imagine being able to<br />

order materials without the worry of<br />

over- or under-ordering – no need to do<br />

a “guesstimate and<br />

add some” to cover<br />

yourself.<br />

EagleView ® makes<br />

all of this a reality.<br />

At its core lies the<br />

patented Pictometry ®<br />

technology which<br />

produces high-resolution<br />

imagery<br />

showing the fronts and sides of<br />

buildings. Pictometry imagery<br />

provides oblique perspectives<br />

from 40 to 45-degree angles as<br />

well as an overhead view.<br />

These images are then stored<br />

and, when an EagleView<br />

roofing report is requested,<br />

advanced algorithms and data<br />

analytics are used to translate<br />

them into a highly accurate<br />

model of the property in<br />

question. These models then<br />

enable detailed structural<br />

measurements to be derived –<br />

including eaves, flashing, hips,<br />

verges, ridges and valleys. The reports are<br />

produced quickly – in a matter of hours –<br />

and available in a variety of file formats.<br />

First in the UK<br />

The EagleView<br />

PremiumReport is a ground-breaking<br />

new offering, and there’s nothing else<br />

like it in the UK. It’s currently available<br />

for sites across London (within the<br />

M25), and Bristol and other major<br />

cities are following close behind. It’s<br />

a truly pioneering technology that<br />

stands to benefit anyone involved in<br />

the roofing industry. However, as with<br />

any successful technology, it’s the early<br />

adopters that will gain a competitive<br />

advantage.<br />

BS 8612<br />

Unlike the revisions to BS 5534, BS 8612 won’t<br />

have a huge impact on contractors but it does<br />

mean they need to make sure that any dry-fix<br />

systems they use that require BS 8612 compliance,<br />

meet the requirements or have BBA certification.<br />

Since the introduction of the revised BS 5534, there<br />

has been a significant shift in the market towards<br />

the use of dry-fix systems.<br />

Stuart Nicholson, Roof<br />

Systems Specialist at<br />

However, the popularity of the products means that there has been a huge<br />

increase in the amount of systems on the market. While they may look broadly<br />

similar, we have become increasingly concerned about inconsistencies in the<br />

durability and weather tightness of some cheaper products. We support the<br />

introduction of BS 8612 because having specific test methods and<br />

requirements to assess all products on an equal basis gives inferior systems<br />

Mark Parsons, Technical Director,<br />

Therefore, it is no surprise that it Russell Roof Tiles<br />

has been welcomed so strongly by ourselves and other leading<br />

Following an increased demand for dry-fix solutions in recent years, a lack<br />

of guidelines has allowed for inferior and inadequate products by some<br />

manufacturers who have not carried out effective testing to enter into the<br />

market, which in turn has led to sub-standard installation and failures.<br />

Our dry-fix products have a proven track record having been used across the<br />

UK for over 25 years and are a dedicated and not a universal fit which<br />

ensures high performance. The materials used are of a high grade and<br />

Fibre Cement Slates<br />



To ensure a weatherproof slate roof, it is important to understand some key design and<br />

installation details. Phil Wilden, Technical Manager at Cembrit, explains how understanding<br />

these factors will ensure a successful installation for the long term…<br />

When designing a slate roof, there are<br />

several interrelated factors which must<br />

be considered before slating starts.<br />

These include determining the exposure of the<br />

site to rain penetration, wind loads and wind<br />

uplift, the pitch of the roof, the overall roof<br />

structure, and consequently, the minimum<br />

headlap for the size of slate selected. This<br />

particular detail is especially important to bear in<br />

mind when the roof verge is under consideration.<br />

To provide a weatherproof roof, slating relies on<br />

double cover, i.e. every part of the roof is covered<br />

by at least two thicknesses of slate. The tails of<br />

slates in one course overlap the heads of the<br />

slates in the next course but one below, by an<br />

amount commonly known as the ‘lap’ (headlap)*.<br />

The lap provides protection against rain and snow<br />

being driven between the joints and passing<br />

upwards over the heads of the slates to penetrate<br />

into the roof space. Should water run down the<br />

roof and enter the narrow gap between the slates,<br />

it can creep diagonally down and across the roof<br />

slates.<br />

The lower the roof pitch, the wider the angle of<br />

creep, and the greater the danger of water<br />

entering the nail holes of the slates in the course<br />

below.<br />

The lap is calculated according to the exposure<br />

rating of the site wind uplift and roof pitch, taking<br />

into account the angle of creep for the size of<br />

slate. Recommended minimum laps and pitches<br />

are provided in our comprehensive publication, ‘A<br />

Guide to Double Lap Slating with Fibre Cement<br />

Slates*.<br />

Best practice - verge installation<br />

One area where good practice is often<br />

misunderstood is at the verge of the roof. This is<br />

important to get right as the perimeter of the roof<br />

is the most vulnerable to wind suction loading. As<br />

Above: Slate fixing at the verge. Below: Cembrit’s Westerland<br />

Slate project<br />

such, the secure fixing of the verge slates will<br />

contribute to creating a long lasting roof covering.<br />

Years of experience of both successful slating<br />

practice and failed roofs, is enshrined in British<br />

Standard codes of practice; 8000 parts 0 and 6,<br />

as well as 5534. The verge is formed from<br />

alternate courses of slate and a half (cut from<br />

double slates) and single slates. This is where the<br />

confusion lies. The second under eaves course<br />

should be a slate and a half, as should alternate<br />

verge slates, see drawing. Rather than use a<br />

slate and a half, many roofers will cut a normal<br />

size slate in half and use that to create the<br />

broken bond. This looks aesthetically pleasing,<br />

but doesn’t give adequate wind uplift resistance.<br />

Installation should be carried out as follows: the<br />

first full slate will require an additional hole<br />

(batten gauge plus 25mm from the tail) to<br />

accommodate the rivet for the next slate and a<br />

half. This next slate and a half will require three<br />

nail fixing holes on the batten line, two rivet holes<br />

to hold the tail and an additional hole to<br />

accommodate the rivet for the subsequent single<br />

verge slate.<br />

When trimming to verges, valleys and hips, avoid<br />

using pieces less than 150mm wide. If possible,<br />

use a slate and a half with the cut edges<br />

protected to prevent cement run off due to<br />

exposure to weather.<br />

In practice<br />

A recently completed five bedroom bespokedesigned<br />

house (built on the site of an original<br />

three bedroom bungalow) showcases the correct<br />

method for installing verge slates. The roof was<br />

being replaced as part of the larger project. On<br />

the original bungalow, concrete roof tiles were<br />

installed and the weight of the tiles had made its<br />

roof start to dip in the middle. The typical weight<br />

per m² of interlocking concrete tiles equals 45-<br />

50Kg. In contrast, a m² of fibre cement slates<br />

weighs just 20Kg making them a lighter, versatile<br />

alternative and the perfect choice for this project.<br />

The slates were chosen by Mid Kent Roofing and<br />

professionally installed according to the relevant<br />

British Standards. Particularly worthy of attention<br />

is the verge detail, as seen in the photograph<br />

(left) showing double slates cut to a slate and a<br />

half. With two rivets and three nails, there is very<br />

little chance that environmental conditions will<br />

affect the verge slates, which, as discussed, can<br />

be vulnerable to lifting if fitted incorrectly.<br />

Gutter Lining<br />


Ampteam tells <strong>Total</strong> <strong>Contractor</strong> why it feels training makes things easier for all in the<br />

supply chain...<br />

The series of project photographs below and<br />

right show pre and post images of a Unifold<br />

installation. The final result, I am sure<br />

anyone who has seen gutter installations before<br />

would agree, looks good – well not just good, but<br />

very good.<br />

As we all know, high quality installations don’t<br />

just happen by accident.<br />

We decided quite some time ago as company<br />

policy not to just supply a consignment and<br />

expect those on site – who may have never<br />

installed Unifold before – to just get on with it!<br />

In fact, we would never supply to anyone unless<br />

our training programme had first been completed<br />

to our satisfaction. This protects our system, the<br />

installer / site operative, and ultimately the end<br />

user customer.<br />

Approved contractors<br />

This particular Unifold liner (see images) was<br />

installed by one of our approved contractors and<br />

“We would never<br />

supply to anyone<br />

unless our training<br />

programme had first<br />

been completed to our<br />

satisfaction”<br />

their site operatives have<br />

been trained to install<br />

the system at our<br />

factory facility.<br />

Following<br />

training, this<br />

level of quality is<br />

what we have<br />

come to expect<br />

from our installers.<br />

Guarantees<br />

We, like many system suppliers<br />

within our industry, provide a<br />

comprehensive training programme, free of<br />

charge to potential installers of our Unifold Gutter<br />

System. It is only by doing this that we can<br />

provide a constant net result on every occasion<br />

and support our 25 year guarantee which<br />

Above and below, top: The completed Unifold liner<br />

installation. Bottom, left and right the roof was not draining<br />

correctly and ponding water was causing serious problems<br />

includes the installation<br />

as well as quality of<br />

the materials and<br />

manufacture.<br />

Apart from<br />

teaching the<br />

techniques<br />

involved with<br />

installation and<br />

site joint<br />

manufacture, we feel<br />

it is important that there<br />

is an understanding of the<br />

technology behind the system and why<br />

the product, correctly installed, will perform to the<br />

highest standard whilst at the same time<br />

providing an installation that the installers can be<br />

justifiably proud.<br />

“High quality<br />

installations don’t just<br />

happen by accident”<br />

The course involves practical training and a<br />

theory presentation followed by a multiple choice<br />

test and, when successfully completed,<br />

candidates are awarded a numbered installer’s<br />

card with photographic identification.<br />

More to learn<br />

We have found the course is beneficial for<br />

business owners and contracts managers, as<br />

well as site operatives to attend, as there is more<br />

to learn than just the installation practices.<br />

Roofing Tutor Focus<br />


David Mallory, Leeds College of Building’s roofing and tiling lecturer, tells <strong>Total</strong> <strong>Contractor</strong><br />

about hard work, punctuation and giving every student his personal mobile number.<br />

07:00: I’m definitely a morning person. I<br />

get up at ten past six and I like to get into<br />

college at seven so that I can prepare<br />

properly for the day. Each group I teach has their<br />

own course file and I like to make sure that all the<br />

paperwork is up-to-date. I have been a roofing<br />

and tiling lecturer for 15 years. I started off, like<br />

my students, as an apprentice roofer and worked<br />

up to running my own company. One day I had<br />

been arguing with a customer who didn’t want to<br />

pay me, when I saw a job as a roofing lecturer<br />

advertised and decided to apply. I got that job and<br />

haven’t looked back.<br />

At first, I worked part-time as a lecturer, parttime<br />

as a roofer but now I teach full time. Very<br />

occasionally, a friend from the industry will need<br />

a difficult detail doing and I’ll help him out with<br />

that.<br />

Most of my time is spent teaching in the<br />

workshop or the classroom. I also have an<br />

increasing workload of admin, including marking<br />

assignments, updating records and<br />

communicating with employers, plus managing<br />

agents such as CITB. Part of my job now is to<br />

correct my students’ spelling, punctuation and<br />

grammar when I’m marking written work.<br />

Around 70% of the apprentices who come to us<br />

don’t have GCSEs in English and Maths, so they<br />

will have lessons in those subjects too, once a<br />

week.<br />

09:00: Workshop sessions start. Some days we<br />

will have four one-and-a-half hour sessions in<br />

the workshop, on others we have two sessions<br />

with the rest spent in the class room.<br />

I take a register, give a little tool box talk on any<br />

changes that have taken place in the workshop,<br />

any PPE they need and what else is going on. If<br />

students don’t turn up, I have to chase them.<br />

David Mallory, Leeds College of Building’s roofing & tiling lecturer working on the rigs and in the classroom with his apprentices.<br />

David spent a number of years on the tools before making the move into teaching after answering an advert<br />

Funny how their phones are often turned off<br />

when I call them….<br />

My three groups of apprentices are all employed<br />

full-time and come to us in two-week-long<br />

blocks. As well as teaching them in college, I visit<br />

them on site to assess the work that they are<br />

doing with their employer. There are 12 students<br />

in my first-year group and 17 in my second-year<br />

group, both working towards their Level 2 C-Skills<br />

qualification. I also have 11 students studying for<br />

a third year to get a Level 3 qualification. My<br />

colleague, Chris, also has groups of first and<br />

second-year students.<br />

“One day I had been<br />

arguing with a<br />

customer who didn’t<br />

want to pay me, when I<br />

saw a job as a roofing<br />

lecturer advertised”<br />

Most students are aged between 16 and 24. After<br />

that there is no grant support for apprentices. I do<br />

have one student who is 49 who has been<br />

working in construction for a while and wants to<br />

train himself up.<br />

10:30: We break for 15 minutes, and then it’s<br />

back to the workshop. The apprentices all must<br />

work through 22 projects over two years that will<br />

help give them the skills to deal with all tiles,<br />

slates and plain tiles.<br />

The college has good links with several<br />

manufacturers who supply us with their products.<br />

It’s important that the apprentices get to work<br />

two products are fixed in the same way, so they<br />

must follow the manufacturer’s instructions.<br />

All the apprentices will be at different stages of<br />

different projects, depending on their skill level,<br />

their previous experience and their level of<br />

motivation. In any group, there will be the full<br />

spectrum of commitment from those that are<br />

eager to learn as much as possible, to those that<br />

wish they weren’t there at all. For those that are<br />

keen and finish more quickly, I give them extra<br />

projects to challenge them and keep them<br />

interested.<br />

Every year we put our most talented apprentices<br />

forward to compete in the SkillBuild competition.<br />

Last year we had two brothers winning gold and<br />

bronze in the finals in Birmingham, which was a<br />

proud moment for the College.<br />

I was also proud when one of my students was<br />

one of ten finalists in Redland’s Apprentice of the<br />

Year Competition last year. This is a bit different<br />

from SkillBuild in that the apprentices have to<br />

submit a written entry and the two-day<br />

competition involves a range of activities, not just<br />

practical roofing skills.<br />

At the college, the help and support we receive<br />

from Redland is hugely appreciated. The donation<br />

of materials, for example, enables the trainees to<br />

not only encounter new and varied products and<br />

materials, but also the chance to experience new<br />

installation techniques.<br />

One of the things I enjoy most about my job is<br />

seeing the apprentices master new skills. For<br />

instance, I force them to use hand cutters rather<br />

than the petrol ones they use on site. At first, they<br />

moan and groan because they are more difficult<br />

to use, but by the middle of a valley they are<br />

getting it right. It’s great to<br />

see the satisfaction on<br />

their faces.<br />

We are lucky to<br />

have really good<br />

workshop<br />

facilities at the<br />

Hunslet<br />

Campus. It was<br />

purpose-built two<br />

years ago and<br />

there’s a second<br />

building under<br />

construction next door. The<br />

College hopes to secure a third plot<br />

adjacent to that which will bring all our three<br />

campuses into one location.<br />

13:00: In the afternoon, we may continue in the<br />

workshop or have sessions in the classroom.<br />

Before we start a project in the workshop, I like to<br />

give the apprentices an overview of what we will<br />

be doing. They may only have worked with one<br />

manufacturer’s systems or on one site, so they<br />

often don’t appreciate that there are different<br />

ways of doing things.<br />

With any new group of students, I always put my<br />

mobile number on the board and tell them to ring<br />

me if they need any advice or information. I get<br />

calls from lots of former students, years after<br />

they’ve left college, who are on a job and need to<br />

know how to do something. I’m always happy to<br />

help. One thing I always ask now, though, is that<br />

they call during working hours. That’s because I<br />

once received a call at 2am from a student who<br />

had been out celebrating gaining his<br />

qualifications who was calling to tell me how<br />

great I was!<br />

They often don’t have any<br />

The best piece of advice I ever had was from a<br />

manager and mentor during the early part of my<br />

teaching career, Chris Ferguson, who’s now<br />

retired. He said: “Don’t back them into a corner.<br />

Always give them a way out”.<br />

16:00: The end of my day. I have two daughters,<br />

aged nine and 12, and I spend as much time as I<br />

can with them and my wife. We do outdoor<br />

activities like biking and camping and until<br />

recently I’ve been volunteering with my<br />

daughter’s scout group; first as a parent helper<br />

then as a scout leader. My students wouldn’t be<br />

surprised to hear that I was presented with a<br />

certificate at the 2017 End of Year Awards for<br />

being the scout leader most likely to say the<br />

phrase “It’s your time you are wasting”.<br />

I enjoyed my first career in roofing. It was all I<br />

ever wanted to do, even when teachers tried to<br />

discourage me because construction was only for<br />

the “bad lads”. If I could tell my younger self<br />

anything, I’d want to warn myself just how hard it<br />

was going to be. The roofing is the easy part, it’s<br />

all the other things related to running a business,<br />

dealing with customers and the taxman and<br />

getting paid that’s difficult.<br />

Step by Step<br />


TILES TO BS 5534<br />

Marley Eternit has put together the following general guide to help roofers install interlocking<br />

clay tiles to the BS 5534 Standard, but advises contractors to always check the<br />

manufacturer’s specific instructions and get a fixing specification for each project.<br />

Large format clay interlocking tiles are<br />

growing in popularity as roofers look for a<br />

more cost effective, easier to fix clay tile,<br />

that doesn’t require specialist skills. Although<br />

they are quick to install, clay interlocking tiles<br />

must be fixed according to BS 5534 on all new<br />

and re-roofing projects. Below, we’ve provided a<br />

guide to installing interlocking double roman and<br />

interlocking clay pantiles:<br />

Step 1 - Battens and underlay<br />

First of all check that all battens have been pregraded<br />

to meet BS 5534 requirements.<br />

Underlays must also be BS 5534 compliant and<br />

installed in line with the Standard’s<br />

recommendations.<br />

Step 2 - Eaves ventilation<br />

To ventilate the<br />

eaves, a 10mm,<br />

25mm or eaves<br />

vent plus system<br />

can be used with<br />

2 x 6m continuous rafter roll.<br />

Step 3 - Eaves<br />

BS 5534 requires<br />

that all perimeter<br />

tiles should be<br />

fixed with a<br />

minimum of two<br />

mechanical fixings.<br />

2<br />

3<br />

This can be achieved by head fixing each tile with<br />

the appropriate size aluminium clout head nail,<br />

and an eaves clip nailed to the fascia board and<br />

located over the side lock of the tile.<br />

Step 4 - Verges<br />

Tiles need to have<br />

two fixings to meet<br />

BS 5534<br />

requirements. They should either be head nailed<br />

and fixed with a dry verge, or if using a traditional<br />

mortar finish, they can be head nailed and fixed<br />

with a verge clip.<br />

Step 5 - Tile laying<br />

Most clay<br />

interlocking tiles<br />

will have a flexible<br />

gauge to make<br />

installation easier.<br />

However, there is an interlocking pantile on the<br />

market with a fully open gauge, which means the<br />

tiles can be laid in a similar way to concrete roof<br />

tiles, without the need for complicated setting<br />

out.<br />

Step 6 - Nailing and clipping<br />

BS 5534 requires<br />

that all single lap<br />

tiles should be<br />

mechanically<br />

fixed.<br />

The level of fixing will depend on the roof<br />

specification.<br />

4<br />

5<br />

6<br />

Clay interlocking tiles should be mechanically<br />

fixed with at least one aluminium clout head nail<br />

and / or tail clipped.<br />

One piece clip and nails, like SoloFix, can save<br />

up to 30% on roof clipping time.<br />

Step 7 - Valley<br />

The valley can be<br />

installed with a<br />

universal GRP<br />

valley system and small pieces of cut tiles at the<br />

hip and valley can be secured using retention clips.<br />

Step 8 - Hips<br />

Hips can be fixed with hip<br />

fixing packs for use with<br />

traditional mortar, or a dry<br />

hip system to provide a low<br />

maintenance mortar-free<br />

mechanically fixed solution.<br />

Step 9 - Ridges<br />

Clay interlocking tiles will often have their own<br />

matching or concrete ridge tiles which can be<br />

installed with security fixings. However, a dry ridge<br />

system has the double benefit of helping to ensure<br />

compliance with the fixing requirements, while<br />

providing the required continuous ventilation at<br />

the roof apex.<br />

Step 10 - The finished roof!<br />

Please note that all dry-fix systems used should be<br />

compliant with the new BS 8612 Standard.<br />

Roof Windows<br />



If not selected and installed correctly, a roof window can be a potential point of leaks and<br />

affect the thermal performance of the building. Lee Griffiths, Technical Sales Manager GBI at<br />

Dakea, discusses the factors to consider when selecting a roof window, and provides a stepby-step<br />

guide on how to install a roof window and get it right first time.<br />

Establishing the customer’s exact<br />

requirements from the outset sounds<br />

obvious but most definitely avoids<br />

disappointment further down the line.<br />

Consider the size and number<br />

of roof windows<br />

A good starting point is establishing the size of<br />

the roof window and the number of windows<br />

required. Bigger windows, of course, admit more<br />

daylight, but it is also worth considering a number<br />

of smaller windows instead, as a better overall<br />

effect can sometimes be achieved.<br />

Other factors worth discussing<br />

with your client<br />

If thermal performance is a<br />

priority there are roof<br />

windows that keep houses<br />

warm in the winter and<br />

prevent heat build-up in<br />

the summer. Systems that<br />

feature double-pane<br />

window glazing units filled<br />

with krypton and covered in a<br />

double low emission coating will<br />

achieve this.<br />

1<br />

Reviewing how the room will be used can also<br />

throw up questions when it comes to noise<br />

protection. At Dakea we have introduced our<br />

Noise Block technology - a 6mm thick, toughened<br />

outer pane, flashing system and inner pane with<br />

two layers of noise-reducing film. This means<br />

external noise is reduced 50% more effectively<br />

than comparable windows on the market.<br />

Installing correctly first time<br />

There are also a few challenges to combat when<br />

installing a roof window and it depends on the<br />

particular situation. This step-by-step guide<br />

focuses on an outside-in sequence for the Ultima<br />

window.<br />

Firstly, remove the battens to the<br />

extent of the framed area.<br />

The aperture on the roof<br />

must be at least 6cm<br />

wider and 12.5cm (for tile<br />

roofing) higher than the<br />

outer size of the window.<br />

Cut out the roofing underlay<br />

and fix it with staples, cutting<br />

away the excess.<br />

Determine the correct height of the window<br />

“An un-insulated gap<br />

between the rafter and<br />

back of the window<br />

frame means water and<br />

air can pass through”<br />

installation (for tile roofing only) and fasten a<br />

batten to support the frame – level and position<br />

8cm above the tiles.<br />

It is essential to repair the roofing membrane. An<br />

un-insulated gap between the rafter and back of<br />

the window frame means water and air can pass<br />

through. Exposed gaps can cause interior surface<br />

damage and colder room temperatures,<br />

compromising energy efficiency and a resulting<br />

rise in heating costs.<br />

Meeting various regulation requirements is also<br />

important. Filling the un-insulated gap between<br />

the rafters and the roof window will ensure it is<br />

compliant with Part L1B of the Building<br />

Regulations.<br />

Many installers choose to use rigid foam cut to fit<br />

from larger, premium priced sheets. While this leads<br />

to a secure and tight fit around the frame, it<br />

The impact to which the window will be exposed<br />

is also worth considering. With increasingly<br />

extreme UK weather conditions, options that offer<br />

storm resistance and glass protection against<br />

impact from both the exterior and the interior are<br />

advisable – some include a lifetime guarantee<br />

against hail damage for the pane.<br />

Roof Windows<br />

can prove troublesome and time consuming,<br />

creating onsite debris and waste.<br />

A product that features free installation accessories<br />

and can address installation issues like this directly<br />

is our Ultima roof window. This includes the Dakea<br />

IFC Insulating Foam Collar – a rebated foam profile<br />

manufactured to fit the window frame. It offers<br />

superior insulation and reduces installation time to<br />

approximately three minutes per window.<br />

Once the frame is assembled, pass it through the<br />

opening on to the support battens and check<br />

alignment, replacing the sash to test that it opens<br />

and closes; Secure all the brackets with screws.<br />

After removing the sash once more, the roofing<br />

membrane must be substituted to restrict water<br />

and air ingress. Traditionally available as a large<br />

underlayer sheet, the membrane must be cut to<br />

size so it fits snuggly around the window. Using<br />

the remaining membrane, a gutter system should<br />

then be formed to catch any water ingress and<br />

direct it away from the opening in the roof.<br />

“Roof window<br />

installations can<br />

produce several time,<br />

procedure and<br />

weather-related<br />

challenges”<br />

Furthermore, an installer knows this process<br />

requires a high level of accuracy to ensure a<br />

water and airtight seal. For larger projects<br />

containing four or more roof windows, the<br />

complete process may take considerable time to<br />

cut and install roofing membrane and foam. The<br />

Dakea RUC Underfelt Foil Collar offers another<br />

time-saving solution. The single piece of stretchable<br />

fabric removes any need for cutting and joining<br />

membrane material. Slide this underneath the<br />

battens and fix securely to create a water and<br />

airtight barrier in a simple 15-minute process.<br />

To complete the installation, fix the flashing and<br />

covers to the bottom, sides and top of the frame<br />

then simply replace the tiles and the sash.<br />

Roof window installations can produce several<br />

time, procedure and weather-related challenges<br />

Living Roofs<br />



By Jonathan Brown, Fixfast<br />

The living roof market is booming. It grew by<br />

over 17% last year, with no sign of slowing.<br />

This is great news for contractors able to<br />

install living roofs, who should see a healthy<br />

pipeline of projects.<br />

But with this growth comes challenges; as more<br />

living roofs are installed, the risk of underengineered<br />

systems increases. Problems with<br />

insufficient drainage, soil erosion or compromised<br />

fire safety can all cause a living roof to fail<br />

prematurely. If this becomes common, building<br />

owners could lose their appetite for living roofs and<br />

reduce opportunities for contractors.<br />

Fortunately, the simple installation of a living roof<br />

retention system can prevent these issues from<br />

occurring. But not all retention systems are created<br />

equal. Without carefully selected components, a<br />

system may not extend the roof’s lifespan as hoped.<br />

Here are 10 questions to ask yourself when<br />

selecting products for a living roof retention<br />

system, to ensure your client ends up with a longlasting<br />

living roof.<br />

Q. Have you chosen materials that don’t<br />

rust?<br />

A: Galvanised steel rooftop products are not<br />

appropriate for use on living roofs as their<br />

rustproofing is easily damaged. Use aluminium or<br />

stainless-steel materials to prevent component<br />

deterioration.<br />

Q. Are the materials lightweight & durable?<br />

A: Roof load is a factor in any rooftop<br />

construction. To minimise the weight of<br />

essential components, use materials such as<br />

aluminium, which is sufficiently durable for<br />

rooftop use. Lightweight materials also make<br />

your life easier during installation.<br />

Q. Are the materials non-combustible for<br />

maximum fire protection?<br />

A: Metal components are inflammable and offer<br />

the best balance of durability, design flexibility<br />

and weight. Plastics can be appropriate on a<br />

living roof, but they must be installed correctly in<br />

line with fire safety guidance.<br />

Q. Do the system components have<br />

sufficient drainage holes?<br />

A: Drainage issues are a major cause of living<br />

roof failures. To ensure excess water has<br />

sufficient exit points, choose components with<br />

large and well-spaced drainage holes.<br />

Q. Can the drains be easily accessed for<br />

ongoing maintenance?<br />

A: All drains should be protected to prevent<br />

debris causing blockages. Inspection chambers<br />

are superior to other drain protectors as they<br />

make it easier for the building occupier to inspect<br />

and maintain the drains regularly.<br />

Q. Are your retention angles tall enough to<br />

maintain minimum substrate depth?<br />

A: A minimum substrate depth of 80mm is<br />

recommended best practice for fire safety. When<br />

choosing retention angles for your system, their<br />

edge height must exceed the substrate depth to<br />

help preserve it over time.<br />

Q. Could your components damage the<br />

roof’s waterproofing?<br />

A: You should think about keeping the membrane<br />

intact throughout the installation, including the<br />

impact of damage by following trades. Use L-<br />

shaped retention angles, rather than solely vertical<br />

edges, as this will spread the load, protecting the<br />

waterproof membrane from potential breaches.<br />

Q. Is your living roof protected from soil<br />

slippage?<br />

A: Soil slippage can cause drainage issues and<br />

compromise fire safety. In barrel-vaulted and<br />

pitched roofs, you should install anti-slump<br />

products to hold the sedum blanket securely in<br />

place.<br />

Q. Are your firebreaks secure?<br />

A: Unbroken fire breaks are essential for living<br />

roof fire safety. Use retention angles to stop<br />

plants from growing into them. To protect gravel<br />

firebreaks from strong winds and heavy boots,<br />

use large pebbles of between 20-40mm, and<br />

apply a gravel adhesive to hold them in place.<br />

Q. Is there safe access for maintenance?<br />

A: A successful living roof requires regular<br />

maintenance. Have you provided a safe means of<br />

access for the occupier to reach the roof?<br />

Permanent, collective protection (e.g. ladders and<br />

rails) is better than a temporary or personal<br />

system as more people can safely use it.<br />

By asking yourself these 10 questions, and<br />

choosing the right retention system as a result, you<br />

can ensure your living roof installations thrive as<br />

intended. A properly engineered living roof will last<br />

longer, look better, and do more for the environment.<br />

As demand for living roofs continues to rise,<br />

those contractors with a good reputation for<br />

delivering long-lasting living roofs – underpinned<br />

by well-chosen retention systems – will be bestplaced<br />

to benefit.<br />

Fragile Roofs<br />



A staggering number of falls from height continue to be linked with fragile roofs. Employers<br />

are faced with harsh fines and court appearances due to unsafe working conditions and not<br />

following the correct procedures for employees to remain safe. Soni Sheimer, General<br />

Manager at Easi-Dec, takes a look at the range of options and solutions that are available to<br />

contractors working at height.<br />

According to the Health and Safety<br />

Executive (HSE), falls from height remain<br />

one of the most common causes of fatality<br />

and major injury in the UK, with falls through<br />

fragile surfaces accounting for 22% of all<br />

accidents from height in the construction<br />

industry. The 2016/2017 provisional figures<br />

report that there were 25 fatalities as a result of<br />

falls from height at work.<br />

The key piece of legislation is the Work at Height<br />

Regulations 2005, as amended by the Work at<br />

Height (Amendment) Regulations 2007, which<br />

places a legal requirement for anyone who<br />

contracts others to access and maintain rooftop<br />

equipment on public buildings and housing<br />

developments to ensure proper safety precautions<br />

are in place. Breaching these regulations can<br />

result in a legal prosecution and either a<br />

substantial fine or possible imprisonment.<br />

In November 2017, a Dudley-based contractor<br />

was fined and sentenced to 180 hours community<br />

service and given a six-month prison sentence<br />

suspended for 12 months after a 30-year old<br />

labourer fell more than six metres through a<br />

fragile roof. The man suffered numerous fractures<br />

to his spine, pelvis and shoulder, and will now<br />

never work as a roofer again. The HSE<br />

investigation found that the contractor failed to<br />

address the risk of working at height and on<br />

fragile surfaces before undertaking this roofing<br />

work. He also failed to ensure that fellow workers<br />

had the adequate support to complete this work<br />

and this resulted in it being carried out in an<br />

unsafe manner.<br />

Solutions for fragile roof work<br />

Access to roof tops requires<br />

solutions that are designed to<br />

overcome the challenges of<br />

working on fragile roofs and<br />

provide the user with a safe<br />

working position for skin<br />

maintenance, inspection, cleaning and<br />

re-sealing work.<br />

It is essential that all work at<br />

height is properly planned and<br />

carried out by competent<br />

members of staff.<br />

Selecting the right equipment is<br />

key to reducing the risk of accidents<br />

and falls from height. It needs to be<br />

secure, easy to access and meet<br />

required regulations. Any of<br />

these three types of access<br />

systems can be considered<br />

when accessing roof tops:<br />

1. Mesh walkways are a great<br />

option when access is needed to<br />

run from the eaves to ridge. It provides<br />

the benefit of spreading the weight across the<br />

support battens, allowing the contractors to<br />

confidently move along the full length of the<br />

system. Opting for a solution that is made from<br />

high grade aluminium ensures the structure is<br />

robust, lightweight, and easily transportable.<br />

2. A fully guarded rolling platform, which is<br />

mounted on twin racks, allows contractors to<br />

move up and down the roof on a secure and level<br />

surface. Requiring no penetration,<br />

the structure is easy to<br />

assemble and take down, and<br />

is possible to transport quickly<br />

to other parts of the roof. The<br />

platform moves along a linking<br />

track which is fitted with safety<br />

mesh and battens to provide further<br />

support.<br />

Flat Roofing: Project Focus<br />


<strong>Total</strong> <strong>Contractor</strong> takes a look at Envirotek’s work on a seven storey commercial scheme in<br />

the centre of Cardiff’s Commercial Enterprise Zone; a project which involved some<br />

interesting challenges...<br />

Aseven storey landmark commercial<br />

scheme in the centre of Cardiff’s<br />

Commercial Enterprise Zone, Number<br />

Three Capital Quarter will provide 77,931ft² of<br />

high quality office space, with a central atrium<br />

and terraces on the 6th and first floors providing<br />

features that will ensure a pleasant and<br />

functional workplace for occupiers.<br />

Designed by architects Morgan 2 Hayman, for<br />

developer JR Smart, the speculative office<br />

building adds to the existing 200,000ft² of office<br />

space already occupied at Capital Quarter,<br />

providing high calibre accommodation for<br />

occupiers.<br />

Prestige & performance<br />

Conveniently, located close to Cardiff’s railway<br />

stations and within easy reach of both the city<br />

centre and Cardiff Bay, Number Three Capital<br />

Quarter is part of a major investment in the city’s<br />

Central Business District. The specification of the<br />

office building not only needs to reflect the<br />

prestige and quality required to attract occupiers<br />

today, but also needs to withstand the test of<br />

time to provide an extended service life for<br />

continued high calibre accommodation in the<br />

future.<br />

As a critical element of the building envelope, the<br />

roof build up had to be aligned to this<br />

specification philosophy and the decision to use a<br />

RubberGard EPDM membrane from Firestone was<br />

driven by the developer.<br />

Gary Foster from JR Smart explained: “We had<br />

used Firestone’s RubberGard EPDM membrane on<br />

previous schemes on the Capital Quarter<br />

development and had been very pleased with how<br />

quickly and easily it could be installed with a neat<br />

Images show Number Three Capital Quarter project. Project details: <strong>Total</strong> Roof Area: 1,300m² • Products Used: Firestone<br />

RubberGard EPDM waterproofing membrane • Firestone QuickSeam FormFlash • <strong>Contractor</strong>: Envirotek • Client: JR Smart •<br />

Length of Programme: 2 years<br />

“The team had to<br />

interface the<br />

membrane with<br />

abseiling hooks”<br />

finish. The service life of the roof is very<br />

important for these high calibre office schemes<br />

as it will reduce maintenance requirements and<br />

ensure the building retains its Grade A<br />

performance.<br />

“We’re confident the strength and durability of<br />

RubberGard EPDM will give us a fit and forget<br />

solution, which, as the membrane will be<br />

obscured by the paved overlay, was a vital factor<br />

in the specification.”<br />

The RubberGard EPDM membrane was installed<br />

by Firestone Licensed contractor, Envirotek, on<br />

the main roof area at 7th floor level along with the<br />

terraces at 6th and 1st floor level. The contractor<br />

was involved in the project at design stage to<br />

ensure that sufficient provision was made for<br />

drainage in terms of the number and size of<br />

drainage outlets to maximise roof performance<br />

and avoid any risk of standing water.<br />

Envirotek began the installation by priming the<br />

concrete roof with a bonded vapour control layer.<br />

To further aid drainage to the outlets designed<br />

into the roof, a tapered insulation scheme was<br />

then installed, creating a fall to the drainage<br />

points. This was installed as a two layer<br />

insulation system, with flat insulation board<br />

followed by the tapered board to deliver the<br />

required U-value.<br />

With the insulation in place, the RubberGard EPDM<br />

could be adhered to the roof. Firestone worked with<br />

Envirotek to develop the specification for the<br />

membrane, assisting with wind loading<br />

calculations and optimisation of the membrane<br />

material to support a safe installation process with<br />

high standards of integrity for the finished roof.<br />

44 TC MARCH 2018

Neil Jones from Envirotek explained: “We have<br />

used RubberGard EPDM on many projects but the<br />

technical support and training provided by<br />

Firestone help to ensure that we deliver the<br />

highest standards of quality and workmanship on<br />

every scheme, with a team that are confident<br />

with even the most complex of details.”<br />

The detailing required for the fully-adhered<br />

RubberGard EPDM membrane at Number Three<br />

Capital Quarter was said to be considerable. The<br />

Envirotek team had to interface the membrane<br />

with abseiling hooks around the perimeter of the<br />

seven storey roof, which will be used for window<br />

cleaning purposes, along with steel columns that<br />

support maintenance gantries, structural<br />

steelwork installed on the roof to create visual<br />

shielding for rooftop plant and support steelwork<br />

for a solar PV installation.<br />

For all the penetrations, Envirotek used<br />

Firestone’s QuickSeam FormFlash, an uncured<br />

EPDM flashing laminated to cured seam tape. The<br />

tape was used to fully-encapsulate any details<br />

and regular site visits from Firestone’s technical<br />

support team ensured that all elements of the<br />

installation were fully compliant to the<br />

manufacturer’s guidelines. The building has been<br />

designed with a 1.3m parapet wall around the<br />

perimeter of both the main roof area and the<br />

terraces, and the roofing scheme required a<br />

solution that could be taken up and over the top<br />

of these walls with a metal capping termination.<br />

On the main roof area, Envirotek took the insulation<br />

up the wall, followed by the fully adhered<br />

RubberGard EPDM membrane. For the terraces, the<br />

RubberGard EPDM was adhered directly onto the<br />

concrete face of the parapet wall and terminated at<br />

the top of the wall with a metal capping, before<br />

being obscured by a 50mm cement particle board,<br />

which was mechanically fixed to the internal face of<br />

the wall to provide a decorative finish, visible to any<br />

occupant standing on the terrace.<br />

Indeed, with the installation now complete, none<br />

of the RubberGard EPDM membrane is visible.<br />

Both the roof and terrace areas have been<br />

finished with 600 x 600 x 50mm paving slabs,<br />

which have been mounted onto support pads to<br />

protect the membrane from abrasion and aid<br />

drainage. For the terrace areas, adjustable<br />

support pads enabled the paving to be laid as a<br />

flat walking surface level with access to the 6th<br />

and 1st floor doorways, despite the falls created<br />

by the tapered insulation.<br />

Rolled Lead Sheet<br />



Darren Tutt, Lead Sheet Association Technical Officer, offers some top tips to assist<br />

contractors when working on projects which involve Rolled Lead Sheet.<br />

The Lead Sheet Association has been<br />

providing technical advice and training for<br />

decades across the construction industry.<br />

Using that expertise, we have put together the top<br />

ten issues and queries we deal with on a day-today<br />

basis to help contractors get the most out of<br />

this material.<br />

All the advice and guidance provided here is in<br />

relation to Rolled Lead Sheet manufactured to BS<br />

EN 12588 and conforming to the Standard set out<br />

in BS 6915. More detailed information about the<br />

following issues can be found in the LSA’s<br />

Complete Manual, or if you want a handy guide to<br />

basic information when you are out and about, on<br />

our new App – search LSApp – it’s available for<br />

Apple and Android.<br />

We are also on the other end of the phone to<br />

support contractors with more complex enquiries<br />

where we handle thousands of calls a year<br />

through our technical enquiry line. We know that<br />

contractors have to contend with many aspects of<br />

roofing and often bring in lead or hard metal<br />

specialists, but by sharing the following we hope<br />

to give you some guidance on the things to look<br />

out for.<br />

1. Ventilation<br />

The consequences of installing lead sheet on an<br />

unventilated substrate can be detrimental to the<br />

expected longevity of the roof in question. All lead<br />

sheet should be laid on a thoroughly ventilated<br />

substrate. That means that under the decking<br />

the lead sheet that actually sits on there should<br />

be a minimum 50mm through-ventilated path<br />

with no stagnant air pockets. Even vertical<br />

applications should be ventilated although here<br />

the ventilated path can be reduced to 25mm.<br />

“All lead sheet must be<br />

laid on a minimum fall<br />

of 1:80 which equates<br />

to a little under 1<br />

degree”<br />

2. Neoprene expansion joints<br />

Traditionally, lead gutters incorporate steps or<br />

‘drips’ in their design. These are intended to break<br />

up the lengths of lead sheet used to ensure that<br />

thermal expansion is within guidelines for<br />

individual pieces of lead. In many instances this<br />

works wonderfully well, but in others there simply<br />

isn’t the height to allow for them. Our advice is<br />

simple really – wherever possible stick to<br />

traditional tried and tested methods and only use<br />

neoprene expansion joints as a last resort. With<br />

46 TC MARCH 2018

new-build design, the inclusion of drips should<br />

always be considered first.<br />

3. Lead sizing<br />

Getting the thickness of the lead sheet right for a<br />

particular application is essential. Lead comes in<br />

a range of codes (thicknesses) yet so many times<br />

we see the wrong codes of lead used or the<br />

individual pieces of lead sheet installed in too<br />

large a piece. Lead sheet is a metal of low<br />

strength but provision for this is made by sizing<br />

and fixing within certain parameters so that the<br />

risk of fatigue cracking or ‘creep’ is minimised.<br />

Check the Manual – or App – to make sure you<br />

get the right code and the right length, lead is<br />

incredibly reliable if you get these things right and<br />

will last an incredible amount of time.<br />

4. Underlays<br />

When asked what underlay – if any – is required<br />

the answer is quite simple. If exterior quality<br />

plywood, penny gap softwood boarding, penny<br />

gap oak boarding, stone, concrete or brick is<br />

used, a building paper to BS 1521 Class A should<br />

be used. It is only with penny gap softwood<br />

boarding that geotextile fleece can be used as an<br />

alternative. In all cases there must be throughventilation<br />

present.<br />

5. Flashing lengths<br />

Lead flashings should nearly always be installed<br />

in 1.5m lengths, however there are exceptions.<br />

Lead flashings to asphalt, bituminous felt, or<br />

single ply roof coverings are continuously bonded<br />

along one side, therefore it is essential to limit the<br />

lengths to 1m so that the thermal movement of<br />

the lead sheet is not affected when exposed to<br />

long periods of summer sun.<br />

“We see lead flashings<br />

or other edges of<br />

roofing, cladding and<br />

weatherings missing<br />

any form of restraint to<br />

their free edges”<br />

6. Falls<br />

All lead sheet must be laid on a<br />

minimum fall of 1:80 which<br />

equates to a little under 1<br />

degree. Anything less may<br />

encourage ponding water and<br />

a build-up of debris and dust<br />

or staining of the lead sheet<br />

which should be avoided.<br />

7. Clipping<br />

There are so many instances where<br />

we see lead flashings or other edges of<br />

roofing, cladding and weatherings missing<br />

any form of restraint to their free edges. All such<br />

edges must be adequately clipped to prevent<br />

lifting and distortion in high wind conditions, and<br />

it is amazing to see how often these are missed<br />

out or not considered at all. Clipping of lead sheet<br />

varies considerably in both material used and the<br />

distances that they are set apart – this is covered<br />

in detail in the LSA Manual.<br />

8. Laps<br />

A lot of enquiries we get assume that a flashing<br />

should lap over a pitched roof covering by 150mm.<br />

This is true for a 30 degree slope, but what a lot of<br />

people don’t realise is that the lap length is wholly<br />

dependent on pitch and can vary considerably. We<br />

usually end up referring clients to the 75mm lap<br />

diagram that we show in the manual. Laps can<br />

vary between 75mm to 395mm on pitched roofs or<br />

even more if the exposure of a particular building<br />

is considered severe. It is also worth noting that<br />

the lap should always be taken from the lowest<br />

row of fixings in whatever it is covering.<br />

9. Fixing<br />

The fixing of lead sheet is carried out in many<br />

different ways, all of which are dependent on<br />

the particular application. For instance, a lead<br />

roofing bay on a roof with a small pitch of up to<br />

3 degrees differs in the arrangement and<br />

position of its fixings when compared to the<br />

same roofing bay on a higher pitch. These<br />

differences are very important to ensure correct<br />

installation and future longevity.<br />

Above: Lead is a contemporary building product that has<br />

been used by architects in many different scenarios<br />

“The consequences of<br />

installing lead sheet on<br />

an unventilated<br />

substrate can be<br />

detrimental to the<br />

expected longevity of<br />

the roof in question”<br />

10. Damp Proof Courses (DPCs)<br />

Lead DPCs and trays are designed to prevent<br />

moisture that penetrates brick or stonework<br />

finding its way into the building. Many of the<br />

calls we receive regarding these centre around<br />

mysterious staining appearing. In nearly all<br />

cases this is caused by failure to treat the lead<br />

that is built into the walls with bituminous<br />

black paint on both sides prior to fitting. This<br />

coating prevents free alkali in fresh Portland<br />

cement mortar and sulphuric acid vapours that<br />

are contained in the moisture in chimneys from<br />

corroding the lead sheet.<br />

Opinion<br />



By Mark Hibberd, National Field Manager – Roofing at Sika<br />

If I was a school leaver considering my career<br />

options ahead of me, why would I choose to<br />

take a job in the roofing industry? At face<br />

value, it’s a decision that would see me spending<br />

the best part of my working life out in all<br />

weathers, doing a physically demanding role that<br />

can be dirty and unsafe.<br />

Most roofers when asked would probably not say<br />

they always aspired to be a roofer from a young<br />

age. Most roofers have fallen into the roofing<br />

industry by accident or default. So how can we<br />

encourage younger generations to embark on a<br />

career in roofing?<br />

Manufacturer training has improved significantly<br />

and is backed up by Trade Associations and<br />

national industry training boards to give each<br />

roofing operative a qualification, meaning<br />

recognition in the industry and the chance to<br />

progress however far they wish. Once an<br />

operative has a qualification and gains<br />

experience in the installation of different roofing<br />

systems, they become a prime target for<br />

manufacturers looking for Field Technicians to<br />

train in the use of their systems, products, and<br />

inspect installations to maintain high<br />

workmanship standards.<br />

Some may move into site<br />

supervision, contract management<br />

or chance their arm at starting up their<br />

own contracting organisation. Experienced<br />

installation operatives are much sought after – they<br />

do say you can’t teach experience.<br />

Working practices<br />

We can’t change the weather but we can change<br />

working practices. Health and safety protocols<br />

are at the forefront of any company’s strategy.<br />

Sites now have excellent welfare facilities,<br />

stringent PPE and place the emphasis on the<br />

safety of workers at all times. Products also have<br />

to meet or exceed strict guidelines, particularly<br />

when it comes to installation.<br />

“We can’t change<br />

the weather but<br />

we can change<br />

working practices”<br />

Left: Mark Hibberd, National Field Manager –<br />

Roofing at Sika<br />

Manufacturers, such as ourselves,<br />

are constantly reacting to<br />

feedback from operatives and<br />

changing installation techniques and<br />

products to mitigate the stress on the<br />

applicator. New products are designed to be far<br />

less demanding and cleaner to use than<br />

traditional methods.<br />

Spray technology has made major in-roads into<br />

most manufacturers’ portfolio of products which<br />

negates the need for site operatives to spread<br />

adhesives with rollers, brushes or squeegees and<br />

saving from future exo-skeletal problems. Selfadhered<br />

membranes are seen as a progressive<br />

way of installing single ply membranes for the<br />

same reasons, again with Sika leading the way.<br />

All this, combined, gives me such hope for the<br />

future of the industry.<br />

Long-term career opportunities<br />

The roofing industry is now safer, cleaner and<br />

less physically demanding than ever before and<br />

also offers more long-term career opportunities<br />

for young professionals than we’ve ever seen.<br />

This has helped draw more talented professionals<br />

into roofing, something we’re personally seeing<br />

through the Sika apprenticeships, industrial<br />

placements and internships. With more high<br />

quality roofing professionals using high quality<br />

products, the roofing industry will continue to<br />

deliver high quality roofing results for projects of<br />

all shapes and sizes up and down the country for<br />

many years to come.<br />

A new batten end clip, designed to make it easier for roofers to install dry verges in<br />

accordance with the new BS 8612 Standard, has been launched by Marley Eternit.<br />

Marley Eternit says its new c-shaped clip is a quick and easy way of complying with BS 8612<br />

and provides a strong fix. The clip is designed to fit securely onto the end of the batten, with a robust metal plate for the dry verge to be fixed into, keeping the nail<br />

locked into place. Alex Gill from Marley Eternit, explained: “Our new clip requires no nails and has sharp teeth which grip into the batten, making it extremely secure,<br />

as well as being very quick to hammer into place.”<br />

The new batten end clip also features a larger metal face plate, with multiple holes, to make alignment much simpler. Alex added: “There are many different dry verge<br />

products on the market, with varying levels of performance. The new British Standard addresses some of the concerns the industry had not only about inconsistencies<br />

between the quality of products, but also ensuring the systems are easy to fix correctly and securely.” www.marleyeternit.co.uk<br />


Crammond Select Homes renovated the Powis Mains Farm in the village of Blairlogie, one of<br />

Scotland’s first conservation villages, using CUPA PIZARRAS’ Heavy 3 slate due to its close<br />

resemblance to the traditional highland slate from Ballachulish that is no longer produced.<br />

Derek Waters of Derek Waters and Sons, the roofing contractor for this project, said: “We use<br />

CUPA PIZARRAS frequently, as the slates are solid and can stand up to any powerful weather.<br />

When we complete each house, it appears to have a perfect aesthetic every time and this is<br />

thanks to this high quality product.” www.cupapizarras.com/uk<br />


A revamped website has been launched by SR Timber as part of the batten<br />

manufacturer’s drive to stay at the top of its game.<br />

Shaun Revill, Trading Director, explained: “Websites are the public face of most companies,<br />

ours included, and businesses in this day and age can’t afford to stand still, so it was<br />

important that we refreshed the look of the site and improved the experience of using it. We’ve<br />

had really good feedback from the people who have used it, and they especially like it when<br />

they access it from their smartphone or tablet.” www.sr-timber.co.uk<br />

Guarantees<br />



Here, Dave Cooper, Customer Technical Services Manager at Tata Steel, explores what<br />

makes a good guarantee and explains the importance of really understanding them.<br />

According to the Cambridge Dictionary, the<br />

definition of a guarantee is ‘a promise that<br />

something will be done or will happen,<br />

especially a written promise by a company to<br />

repair or change a product that develops a fault<br />

within a particular period of time’.<br />

Guarantees are a great way to boost customer<br />

confidence. In fact, they are one of the most<br />

“This often involves<br />

navigating the supply<br />

chain to determine the<br />

outcome”<br />

powerful commitments that a business can make<br />

to demonstrate confidence in their products.<br />

For example, a well-established company, which<br />

has a strong track record, will provide end users<br />

peace of mind that they will be around long<br />

enough to honour a guarantee if required.<br />

As such, when it comes to choosing your product<br />

– especially pre-finished steel products – it is<br />

important to understand what guarantees<br />

manufacturers provide.<br />

Indeed, for most building owners, discovering<br />

whether the products used for their roof and wall<br />

systems will be rectified within the parameters of<br />

the guarantee is a time-consuming and laborious<br />

task.<br />

This often involves navigating the supply chain,<br />

from contractor to contractor, right back to the<br />

manufacturer of the product, to determine the<br />

outcome.<br />

For pre-finished steel products, this can be<br />

especially frustrating if during the lifespan of the<br />

Guarantees<br />

The details<br />

Therefore, it’s important to delve deep into the<br />

details of guarantees to ensure you and your<br />

clients are getting the real deal when it comes to<br />

promises. And there are a few items you should<br />

keep an eye out for:<br />

• Factory cut edges being covered for the entirety<br />

of the guarantee.<br />

• Cover under photovoltaic (PV) modules for the<br />

full guarantee period.<br />

• Fully transferable should building ownership<br />

change.<br />

•Flashings included, if registered for at the same<br />

time as the roof and / or wall.<br />

•Full rectification in the unlikely event of a claim.<br />

“Delve deep into the<br />

details of guarantees<br />

to ensure you and your<br />

Guarantees offered direct to the building owner<br />

present fundamental advantages. Creating a<br />

contractual relationship between the<br />

manufacturer and the building owner will ensure<br />

that if any problems do arise, they can be<br />

rectified quickly and efficiently.<br />

At Tata Steel we offer the Confidex Guarantee. The<br />

guarantee continues to provide the most<br />

comprehensive protection for branded pre-finished<br />

steel products used in roof and wall cladding<br />

applications. It also provides peace of mind for the<br />

building owner, as well as the supply chain.<br />

The Confidex Guarantee is the product performance<br />

guarantee for Colorcoat HPS200 Ultra and<br />

Colorcoat Prisma. It offers up to 40 years of<br />

protection when used in external conventional<br />

building envelope applications – namely roof and<br />

wall cladding – using single skin, built-up or<br />

composite panel construction in industrial and<br />

commercial buildings.<br />

a claim. And for projects<br />

around coastal areas, the Confidex Guarantee has<br />

also been increased from up to 25 to up to 30<br />

years for walls with Colorcoat Prisma.<br />

Requiring no maintenance and inspection to<br />

remain valid, the guarantee also removes the<br />

need to go onto the roof of a property, reducing<br />

maintenance costs and improving safety.<br />

Furthermore, the Confidex Guarantee ensures full<br />

rectification in an unlikely event of a failure,<br />

including factory cut edges, which are covered for<br />

By Jason Wood, Contracts Director at Fixing Point.<br />

Using double skin or twin skin steel<br />

insulated cladding applications is a costeffective<br />

way of improving the efficiency<br />

of a building or renewing a roof covering. The<br />

system usually consists of a profiled metal liner,<br />

a layer of insulation, a spacer system and an<br />

external metal sheet.<br />

The application of this method does, however,<br />

require consideration of a number of different<br />

factors, all of which can impact the overall<br />

stability and effectiveness of a building.<br />

Understanding the installation procedures and<br />

type of roofing and cladding system is essential in<br />

ensuring a building is secure and performs the<br />

way it should.<br />

Getting this wrong could result in multiple<br />

problems further down the line and may even<br />

require the involvement of an additional<br />

structural engineer to create<br />

a solution at more cost.<br />

Spacer systems<br />

explained<br />

The purpose of a spacer<br />

system is to provide<br />

support to the external<br />

sheet at specific points from<br />

the liner sheet.<br />

It therefore needs to be strong enough to<br />

transfer sufficient loading through to the<br />

purlins.<br />

The most common spacer system is the bar and<br />

bracket, which creates a platform for the external<br />

sheet by using steel bars.<br />

These are then supported by steel brackets<br />

attached to the purlins through the liner.<br />

Insulation<br />

Double skin roofing and<br />

wall cladding panels<br />

with a layer of<br />

insulation in between<br />

can provide additional<br />

strength and efficiency<br />

to a building.<br />

The minimum thickness of<br />

insulation for energy use compliance<br />

has, however, increased considerably over the<br />

last 30 years. This means that ensuring you have<br />

the correct insulation at the right thickness is<br />

essential for obtaining the optimum U-value.<br />

It is also very important to realise that different<br />

depths of liner sheets impact the U-value<br />

calculations. For example, installing a 32mm liner<br />

will mean thicker depth of construction is<br />

required to achieve a particular U-value than<br />

using a 19mm liner. The purlin centre spacings on<br />

a building will also affect a U-value calculation,<br />

for example 1.8m vs 1.4m.<br />

Vertical vs horizontal cladding<br />

When planning for your cladding application for<br />

roofing or walling, the most important detail to<br />

understand from the outset is that horizontal and<br />

vertical cladding require different approaches for<br />

their application.<br />

<strong>Contractor</strong>s often think they can use a standard<br />

support system for any type of cladding, but<br />

horizontal cladding is, in fact, much more<br />

complicated than vertical.<br />

With vertical cladding for walls, the steel bars are<br />

fixed horizontally and in line with the purlins<br />

underneath and the profile sheet is then fitted<br />

vertically. Horizontal cladding, however, requires a<br />

56 TC MARCH 2018

Images show the Logistics City project Fixing Point worked on with Deane Roofing, at Motherwell Way, West Thurrock, which demonstrates the use of double-skin horizontal cladding<br />

different approach as the bars must be fixed<br />

vertically, which can be a cause of confusion at<br />

the application stage.<br />

The reason for using vertical bars that span<br />

across the purlins below is so the building can<br />

handle the wind load more effectively. Although<br />

the external weather sheet is designed to<br />

protect the building from adverse weather<br />

conditions, it does also play an important role<br />

in the overall structure of a building. It is,<br />

therefore, essential that it is fitted with the<br />

appropriate support.<br />

The corners of buildings are often more exposed<br />

to higher wind loads, so when using vertical bars<br />

the spacing between them is particularly<br />

important for horizontal wall cladding sections.<br />

At Fixing Point, we recommend the use of the<br />

Gridtite General Purpose (GP) lightweight bar and<br />

bracket system for horizontal cladding. It is<br />

designed to provide a controlled space between<br />

the inner and outer metal sheets that make up<br />

twin skin site assembled roofing and walling<br />

“<strong>Contractor</strong>s often<br />

think they can use a<br />

standard support<br />

system for any type of<br />

cladding, but horizontal<br />

cladding is more<br />

complicated than<br />

vertical”<br />

systems and is strong and stable when sheeted<br />

over.<br />

Using specialist systems for horizontal cladding<br />

might seem like an unnecessary expense at<br />

design stage, but it could ultimately save much<br />

more money in the long run. Because the bars are<br />

fitted vertically, a standard support system is<br />

unlikely to provide a sufficient level of security for<br />

the building and would have less spanning<br />

capabilities.<br />

A system like Gridtite GP also provides the option<br />

of pre-assembled bars, which removes the risk of<br />

misalignment of fixed brackets, and uses a single<br />

layer of quilt insulation. <strong>Contractor</strong>s should,<br />

however, always take note of the capability of any<br />

GP system to accept wind suction and wind<br />

pressure loads. Thermal and structural values<br />

will also vary with every application.<br />

Health & Wellbeing<br />

THE 3 RS: MIND HOW YOU GO...<br />

<strong>Total</strong> <strong>Contractor</strong> takes a look at how Willmott Dixon has been tackling ‘mental fitness’ on its<br />

construction sites through its All Safe Minds initiative.<br />

Willmott Dixon has a long and wellestablished<br />

track record for<br />

safeguarding the physical health of its<br />

employees across the nation’s construction sites.<br />

But as a result of some unsettling figures that<br />

have emerged from the industry over recent<br />

years, they are now also leading the way in<br />

raising awareness of the mental health issues<br />

affecting the sector.<br />

2017 saw the launch of All Safe Minds – a<br />

campaign to encourage mental fitness across the<br />

UK construction sector, particularly amongst<br />

young men who historically have found it difficult<br />

to talk about their problems.<br />

Recent studies commissioned by Public Health<br />

England (PHE) found that certain groups of male<br />

construction workers were at greatest risk of<br />

suicide, with figures at a staggering 3.7 times<br />

above the national average.<br />

As one of the UK’s largest contractors, Willmott<br />

Dixon forged ahead with the All Safe Minds<br />

campaign to ensure that everyone working on its<br />

many project sites across the UK is fully aware of<br />

the support network available.<br />

All Safe Minds aims to instil a 3-step process –<br />

the Three Rs – into daily work culture,<br />

encouraging all employees to:<br />

1. RECOGNISE. Be aware if you or someone you<br />

know is struggling to cope.<br />

2. REACH OUT. Start the conversation. If you are<br />

struggling, talk to someone you trust. Or if you<br />

know a colleague is struggling, offer your support<br />

– simply lending an ear can make all the<br />

difference.<br />

3. REBUILD. Use the resources available to you<br />

to start taking back control.<br />

The All Safe Minds infographic<br />

As part of the All Safe Minds campaign, a hardhitting<br />

infographic has been released, laying bare<br />

some frightening statistics.<br />

Mark French, Head of Health, Safety and<br />

Environment for Willmott Dixon Group, explained:<br />

“Although the way we deal with mental health in<br />

the workplace is improving fast, our industry still<br />

presents some of the most upsetting statistics.<br />

The figures make uncomfortable reading, but we<br />

need to break the taboo and start talking about<br />

how serious this problem is. The infographic<br />

immediately caught the attention of the UK trade<br />

media, who helped it reach hundreds of<br />

thousands of construction personnel within just a<br />

few days of its release.”<br />

As a direct result of the infographic, Mark was<br />

invited to appear on a ground breaking 24-hour<br />

non-stop broadcast for mental health hosted by<br />

Radio City in Liverpool. The major event took<br />

place on Monday 15th January, aka Blue Monday,<br />

and featured contributions from many of the<br />

region’s most respected healthcare professionals.<br />

Mental Health First Aiders<br />

To support the public face of All Safe Minds,<br />

Willmott Dixon is working tirelessly behind the<br />

scenes to increase the routes to support. All<br />

operatives across project sites nationwide receive<br />

an introductory presentation on mental health in<br />

which they are made aware of the help available.<br />

In addition, hundreds of Mental Health First Aiders<br />

(MHFAs) are being trained and deployed to site. The<br />

MHFAs will provide a network of support across the<br />

entire organisation, encouraging employees and<br />

colleagues to seek help if they have existing<br />

problems or realise that they’re starting to struggle.<br />

Every site office will clearly display a new<br />

campaign poster raising awareness of the MHFAs<br />

and making it easy for personnel to contact their<br />

local first aider quickly and discreetly if needed.<br />

All Safe Minds Z-Cards<br />

The latest addition to the campaign is a new Z-<br />

Card, which is issued to everyone attending the<br />

initial mental health session. The discreet<br />

business-card sized aide has been designed to fit<br />

easily into a pocket or wallet, offering a subtle<br />

source of reference, which can be accessed easily<br />

if the need arises. Hundreds of Z-Cards have<br />

already been issued, with thousands more ready<br />

to be handed out over coming months.<br />

Mark French concluded: “Our long-term aim is<br />

for All Safe Minds to become a natural mind-set<br />

for men to seek help if they become overwhelmed<br />

by their personal situation. The Z-Card will be<br />

handed out across our business both internally<br />

and externally. The logo and ethos are already<br />

commonplace across Willmott Dixon sites and<br />

throughout 2018 we will continue to roll the<br />

campaign out to a wider construction audience<br />

until All Safe Minds becomes engrained into our<br />

everyday culture.”<br />

Skyline Fascia, Soffits and Copings – part of Alumasc Water Management Solutions<br />

new entrance and frontage for a major office refurbishment in Spitalfields, London.<br />

For further info on all these cladding updates and more, visit www.total-contractor.co.uk<br />

The project, known as 45 Folegate Street, was led by Tatehindle Architects, who worked<br />

closely with contractor Tetraclad to install the new window and door surrounds. Matt<br />

Swaffer, Tetraclad Contracts Director, explained: “The drawings requested an aluminium<br />

cladding panel which included specific detailing. I was tempted to steer away from it at<br />

first as I had never attempted anything like it before. Some of this detailing was quite<br />

complex but I knew Skyline would produce good fabrication drawings – a service which<br />

other manufacturers don’t offer. It worked out very well.” www.alumascskyline.co.uk<br />






Contour North and South, two luxury housing projects located just off Chircombe Lane<br />

near the river Torridge in Bideford, Devon, have utilised Catnic’s SSR² roof because of<br />

its aesthetic appeal and performance capabilities.<br />

Due to the buildings’ unique curved roof design, Catnic manufactured bespoke curved panels to<br />

ensure an easy to assemble and flexible installation. Martin Riley, Director at Building Firm Riley<br />

& Guy explained: “The SSR² system is extremely flexible in its design, however we had to ensure<br />

that the panels fitted the curvature of the buildings without distorting them.” www.catnic.com<br />

The manufacturer says it has made the film to emphasize Magply’s superiority over other<br />

manufacturers’ boards, in terms of its strength, breathability and low carbon footprint and crucially<br />

its low chloride content which negates any moisture related problems. Importantly, to ensure low<br />

Hackitt review<br />


The Hackitt Review is set to help bring change to the construction industry, and that change<br />

should be for the better, but what does it really mean for contractors operating in the roofing<br />

and cladding sectors? Roy Weghorst, Head of Regulatory Affairs – Fire at Kingspan, gives<br />

<strong>Total</strong> <strong>Contractor</strong> his thoughts...<br />

Ever since the terrible fire at Grenfell Tower<br />

claimed the lives of 71 people in June<br />

2017, there has been a hunger for real<br />

change. It is hoped that the Independent Review<br />

of the Building Regulations and Fire Safety, led by<br />

Dame Judith Hackitt, will help to bring about that<br />

change. The full Review is due to be published in<br />

the next few weeks, but the construction industry<br />

is looking for clear guidance now.<br />

The Interim Report, which was published in<br />

December 2017, highlights six areas where<br />

change needs to happen:<br />

• Regulation and Guidance<br />

• Roles and Responsibilities<br />

• Competence<br />

• Process, Compliance and Enforcement<br />

• Residents’ Voice and Raising Concerns<br />

• Quality Assurance and Products<br />

Each of these will have an impact on contractors<br />

to some degree, and it is important to understand<br />

what that might be.<br />

Regulation and guidance<br />

The first point to be raised is that the rules for<br />

high-rise and complex buildings should be made<br />

more risk-based, in proportion to how great the<br />

risks are, and that people responsible for those<br />

buildings should be more accountable. There is,<br />

of course, already additional guidance for some<br />

high-risk buildings such as hospitals and schools,<br />

but this recommendation would take much more<br />

account of how buildings in general are going to be<br />

used and who is going to be using them.<br />

A possible knock-on effect from this<br />

recommendation could be better levels of<br />

insurance premiums, because the balance of risk<br />

is being managed better.<br />

The next point is a call to action to the<br />

construction industry to take more responsibility<br />

for the identification and specification of safe<br />

solutions that meet the Government “functional<br />

standards”, rather than relying on Government<br />

guidance being kept up to date, or on overprescription<br />

within that guidance. This would be<br />

an important shift – it makes the industry more<br />

accountable, at the same time allowing for<br />

innovative solutions, provided they meet the<br />

requirements.<br />

The last, and probably the most important point is<br />

that “Regulations and guidance must be<br />

simplified and unambiguous”. Nobody would<br />

argue against the claim that aspects of the<br />

current guidance are complicated and that this<br />

may have been a factor in many of the problems<br />

now coming to light. Making the guidance clearer<br />

is the first step towards healing our broken<br />

system.<br />

Roles and responsibilities<br />

We’ve already talked about the industry as a<br />

whole taking more responsibility. This section<br />

looks at the part that individuals must play. The<br />

report states that the main responsibility rests<br />

with “those who commission, design and build<br />

the project”. In other words, if you are a<br />

contractor on a project, you are responsible for<br />

the quality of the build. This may seem like an<br />

obvious thing, but especially on big projects with<br />

complicated supply chains, it is all too easy to<br />

BS 8414 test to assess system performance<br />

assume that somebody else is checking that<br />

nothing is being missed. It is stressed, therefore,<br />

that this responsibility must rest with “clearly<br />

identifiable senior individuals”. Of course, it is not<br />

just the build stage that is coming under scrutiny,<br />

and the next recommendation is that who is<br />

responsible for what should be made clearer over<br />

the whole life of the building.<br />

Competence<br />

Fire prevention in buildings is a complex thing.<br />

Understanding how all the different elements<br />

interact and being able to construct them<br />

correctly requires specialist knowledge and skill,<br />

especially for something like a high-rise building.<br />

The suggestion is that we need to raise the<br />

levels of competence for those involved in fire<br />

prevention, whether it’s design, construction,<br />

inspection or maintenance, and to have a<br />

system of accreditation to demonstrate that<br />

competence.<br />

Hackitt review<br />

Process, compliance and enforcement<br />

Making sure that a building is safe in the event of<br />

a fire doesn’t end with the original design and<br />

construction. Most buildings are expected to last<br />

for decades, and over that time are likely to be<br />

altered in some way or may even undergo a<br />

change of use. They also need maintaining. The<br />

report talks about having a “golden thread” for<br />

high-rise and complex buildings – a means of<br />

keeping a record of any changes and any reviews<br />

of the building to check whether it is still safe and<br />

fit for purpose.<br />

The proper use of BIM at the right level could<br />

potentially be a way of supplying that “golden<br />

thread” – a comprehensive log of every detail<br />

from design to construction, which is then handed<br />

over to the building manager to be updated<br />

throughout the life of the building.<br />

Secondly, these processes need to be enforced<br />

much more rigorously than under the current<br />

system, with proper sanctions for “the few who<br />

do not follow the rules”.<br />

Residents’ voice and raising concerns<br />

All too often, the people who live in these<br />

buildings are not consulted or listened to when<br />

they raise concerns. Yet they are most likely to be<br />

able to spot problems and identify risks. They<br />

should also be able to have peace of mind that<br />

their homes have been constructed safely. The<br />

other steps highlighted above should help to<br />

provide that assurance, and the report also<br />

states that there should be a “clear, quick and<br />

effective route for residents’ concerns to be<br />

addressed”.<br />

Quality assurance and products<br />

Specifiers and contractors rely on manufacturers<br />

to supply good information about the performance<br />

of their products. It is essential that this<br />

information is based on proper testing and<br />

certification. One of the issues highlighted in the<br />

report is that individual products are being used<br />

as part of systems, when those systems have not<br />

been fully tested. In other words, the<br />

performance of individual components should<br />

Changing the way that health and safety is managed on site has greatly reduced risks to construction workers<br />

The installation of the system is every bit as important as the<br />

product performance<br />

not be taken in isolation, but in relation to how<br />

they are installed and how they interact with<br />

each other – something that can only be<br />

assessed through large-scale system testing<br />

such as BS 8414.<br />

From a contractor’s point of view, the<br />

installation of the system is every bit as<br />

important as the product performance, with the<br />

report stating that:<br />

“The integrity and efficacy of product and system<br />

classifications are highly dependent on correct<br />

installation by competent and knowledgeable<br />

persons”.<br />

The report therefore calls for products to be<br />

marketed in a way that is “clear and easy to<br />

interpret” – there must be no ambiguity. It also<br />

highlights the need for the quality of the<br />

“In other words, if you<br />

are a contractor on a<br />

project, you are<br />

responsible for the<br />

quality of the build”<br />

installation work to be overseen. Even the best<br />

performing products and systems can fail if<br />

they are improperly installed.<br />

A call to action<br />

The summary of the report concludes “this is a<br />

call to action for an entire industry”. The<br />

responsibility to bring about real change rests<br />

with all of us to step up and play our part.<br />

Dame Judith reminds us that we have made<br />

such a major shift in culture before; for<br />

example, changing the way that health and<br />

safety is managed on site has greatly reduced<br />

risks to construction workers over the last<br />

decade. Now it is time to make our buildings<br />

safer for those who live and work in them.<br />

We know the direction of travel. The next step is<br />

to look at how we go about transforming the<br />

regulatory system and delivering the quality of<br />

buildings we know we are capable of.<br />

By Tim Vincent, Head of Technical at ROCKWOOL.<br />

Back in July 2017, the Government<br />

announced an independent review of<br />

Building Regulations and fire safety and a<br />

final report is expected no later than Spring 2018.<br />

As we await these findings, it’s important and<br />

helpful to establish clarity in language and<br />

definitions, specifically, the terms noncombustible<br />

and combustible and how these<br />

apply to building materials such as insulation and<br />

cladding.<br />

We can start with basic definitions. Here’s what<br />

the Oxford English Dictionary has to say:<br />

Non-combustible: Made of material that does not<br />

burn if exposed to fire.<br />

Combustible: Able to catch fire and burn easily.<br />

But, how do these terms combustible and noncombustible<br />

relate to building materials?<br />

The European Reaction to Fire classification system<br />

(Euroclasses) is the EU harmonised standard for<br />

assessing the qualities of building materials in the<br />

event of exposure to fire. This standard is a legal<br />

requirement for CE marked construction products<br />

and relevant for both the United Kingdom and the<br />

Republic of Ireland.<br />

As the name suggests, this classification system<br />

assesses and rates the ‘reaction to fire’<br />

performance of construction products, providing a<br />

clear and simple method for comparing the<br />

performance of products when exposed to fire.<br />

When products are tested according to the<br />

Euroclass system, a range of factors are<br />

investigated: ignitability, flame spread, heat release,<br />

smoke production and propensity for producing<br />

flaming droplets / particles. The Euroclass system is<br />

accepted by all European Union States (and is<br />

mandatory where there is a Harmonised Product<br />

Standard) and includes seven classification levels,<br />

from A1 to F.<br />

Understanding these Euroclass classifications is<br />

vitally important.<br />

The Euroclass system states that products<br />

achieving A1 classification are defined as<br />

non-combustible under these Regulations.<br />

Products achieving an A2 classification are<br />

recognised as products of limited<br />

combustibility, offering “no significant contribution<br />

to fire growth”.<br />

Products achieving a rating of B-F are deemed to be<br />

combustible. Where a product has not been<br />

measured for fire safety under the Euroclass system<br />

then it will be classed as F, meaning no<br />

performance declared (NPD).<br />

So, in short, non-combustible equals non<br />

combustible.<br />

Other terms typically used by the industry to<br />

describe product performance, such as, fire safe,<br />

fire proof, fire retardant or flame proof do not<br />

necessarily define that the product is noncombustible.<br />

“Non-combustible” is a legally defined<br />

term within the Building Regulations.<br />

So, how can you determine the Euroclass rating of a<br />

product’s combustibility? In the case of thermal<br />

insulation, all products should be CE marked<br />

against the appropriate harmonised standard. The<br />

Harmonised Product Standard for mineral wool is<br />

BS EN 13162:2012.<br />

Whichever harmonised standard is applicable, by<br />

law, all manufacturers must have their products<br />

independently tested to verify performance claims.<br />

Once a product has been CE marked, the<br />

manufacturer must make publicly available a<br />

Declaration of Performance (DoP). The DoP is a legal<br />

document in which the manufacturer identifies the<br />

product and its intended use, indicating compliance<br />

in relation to the relevant Harmonised Product<br />

Standard and performance in relation to specified<br />

“essential characteristics”.<br />

It’s in the DoP that<br />

you can determine a<br />

product’s Euroclass<br />

rating. The declared<br />

value on the DoP will<br />

match one of the<br />

Euroclasses. For<br />

ROCKWOOL stone wool<br />

insulation, you will find an A1<br />

rating, meaning non-combustible.<br />

So, how is this information of use when considering<br />

building products?<br />

When we consider the fact that more than 95% of<br />

buildings screened and covered by the recent<br />

Government BS 8414 testing program failed to meet<br />

current fire safety standards, it’s clear that<br />

ambiguity, complexity, and confusion exists. This<br />

leaves many people asking: “is there a simple way<br />

to ensure a high rise building is compliant?”<br />

An “obvious solution” was stated by the DCLG on<br />

the 2nd August 2017 in their Advice to Landlords:<br />

“to ensure that the cladding system adequately<br />

resists external fire spread…replace the system<br />

with one where all of the elements of the wall are of<br />

limited combustibility. For example, a wall system<br />

which includes an ACM panel with limited<br />

combustibility filler (category 1) and limited<br />

combustibility insulation, such as, stone wool.“<br />

ROCKWOOL stone wool insulation withstands<br />

temperatures of up to 1000°C and has achieved the<br />

highest possible Euroclass rating: A1 noncombustible.<br />

The Rainscreen DuoSlab, designed<br />

and manufactured specifically for this kind of<br />

application, is already an established choice within<br />

the market and installed on many high rise projects.<br />

Rafter Level<br />



Chris Roughneen, Technical Manager at Isover, explains the importance of finding the<br />

balance between the acoustic and thermal performance of building insulation – especially<br />

when it comes to installing it within pitched roof rafters.<br />

Over the last decade, there has been much<br />

scrutiny on the energy efficiency of<br />

homes, with the focus being placed highly<br />

on the thermal performance of insulation.<br />

However, as the agenda shifts towards achieving<br />

a deeper understanding of how our environment<br />

affects our health and well-being, the emphasis<br />

is starting to be placed on how products can<br />

actually enhance the lives of building occupants.<br />

As such, when it comes to choosing insulation for<br />

any application, you must take into account all of<br />

its properties, including its thermal conductivity<br />

and acoustic performance, as well as its ease of<br />

installation to ensure you can complete the job<br />

quickly and with minimal waste.<br />

Everyone knows that the thermal performance of<br />

insulation is important, but not many people<br />

understand the impact of installing poorly<br />

performing acoustic insulation.<br />

In fact, according to the World Health Organisation,<br />

being exposed to excessive noise can seriously<br />

harm human health and interfere with people’s<br />

daily activities at school, work and at home.<br />

Therefore, when it comes to rafter-level insulation<br />

for pitched roofs, it is important to ensure that not<br />

only is it Building Regulations compliant, but that<br />

it also enhances the general comfort of<br />

occupants. After all, a quarter of the heat in a<br />

building can be lost through an uninsulated roof,<br />

while unwanted outside noise can disturb those<br />

that use the space.<br />

For these applications, I feel a high-performance<br />

glass mineral wool is the best option as there are<br />

many benefits to installing it within the rafter<br />

zone of a pitched roof.<br />

Firstly, it is a very cost effective solution<br />

compared to other materials and some products,<br />

such as our Metac range, can provide an<br />

excellent thermal conductivity of 0.034 W/mK and<br />

possess impressive acoustic properties.<br />

What’s more, it’s also quick and easy to install,<br />

as it’s lightweight and can easily be friction-fitted<br />

between the rafters when cut accurately, which<br />

will result in no slumping or air gaps. If you do<br />

decide to install insulation within the rafters of a<br />

pitched roof, you’ll also have to install a vapour<br />

control layer. However, as many UK properties have<br />

become better insulated and more airtight, moisture<br />

management has risen as a key area of concern<br />

across the market.<br />

If not managed correctly, moisture build-up within<br />

the building fabric can give rise to damp and rot,<br />

potentially damaging the structure of the building<br />

and affecting the day-to-day comfort levels of the<br />

building’s occupants.<br />

As such, a smart vapour control layer (VCL)<br />

should be chosen. Vario XtraSafe is the latest<br />

development in airtightness and moisture<br />

management from Isover. It reacts to changes<br />

within the internal environment, allowing the<br />

membrane to permit trapped moisture to escape<br />

from the structure in summer, whilst preventing<br />

moisture accumulation over the winter months.<br />

With the above in mind, it is vital that you liaise with<br />

a reputable manufacturer to ensure that the correct<br />

insulation is chosen for pitched roofs – or any<br />

application – to not only comply with Building Regs,<br />

but to provide occupants with a warm, comfortable<br />

and peaceful environment to enjoy.<br />

A quick guide to installing Metac, a range designed specifically for pitched roof rafters:<br />

1) Measure and record both the vertical depth of the rafters and the horizontal widths of the gap<br />

between the rafters.<br />

2) Measure and cut the Metac roll with an insulation saw or knife to fit the horizontal width of the<br />

gap between the rafters – adding an extra 10mm width to the measurement to allow for a snug fit.<br />

3) Slit the packaging on the cut section to allow Metac to unroll and wait for the full thickness to<br />

recover. Measure and cut the roll to the required length with a straight edge and sharp insulation knife.<br />

4) Push and friction fit Metac between the rafters, keeping the lower face of Metac flush with the<br />

bottom edge of the rafters.<br />

EWI: Q&A<br />



Chris Kendall, Field Engineer for Baumit, answers <strong>Total</strong> <strong>Contractor</strong>’s questions on his role,<br />

the market in general, training and funding for the energy efficiency sector<br />

TC: Could you tell us a bit about Baumit<br />

and its offering for contractors and<br />

installers…<br />

CK: Baumit offers a wide range of innovative,<br />

tested products from external wall insulation<br />

systems to façade renders, paints and healthy<br />

living indoor plasters. Our brand was created in<br />

1988, following collaboration between two<br />

Austrian building materials companies. Since<br />

then we’ve become one of Europe’s leading<br />

brands with a presence in more than 30<br />

countries.<br />

Images: Baumit has recently opened an EWI training facility in Kent. Email: contact@baumit.co.uk for more information<br />

TC: You’re a Field Engineer at Baumit, can<br />

you describe what this role involves...<br />

CK: Dealing with customers and helping them<br />

overcome on-site installation issues and offering<br />

support where necessary.<br />

TC: What was your path into construction<br />

and your current position?<br />

CK: I was introduced to construction through my<br />

father’s business. I went to Germany in 1991 and<br />

worked there for nine years on external wall<br />

insulation and internal renders and plasters.<br />

When I returned to the UK, I branched-out into<br />

site management, then after a number of years<br />

moved into contract management. From there, I<br />

was offered a field engineer’s position at Baumit.<br />

TC: There still seems to be some outdated<br />

perceptions regarding a career in<br />

construction; how have you found your<br />

time in the construction sector?<br />

CK: Construction is a fantastic trade to be in. It’s<br />

given me a great career path and I’ve always<br />

been in work. I’ve met a lot of wonderful people at<br />

all levels, and no two working days are the same<br />

- there’s always something to learn.<br />

TC: Baumit has recently opened a new<br />

training facility in Kent – what prompted<br />

this decision? Was it because the market<br />

is buoyant, or is it to bridge the skills gap<br />

when installing EWI?<br />

CK: A bit of both, really. With the Government<br />

focused on improving the UK’s energy-deficient<br />

housing stock, the EWI market is undoubtedly<br />

buoyant. Yet, according to contractors, architects<br />

and the like in response to a recent industry-wide<br />

survey, a lack of insulation installation experience<br />

is seen as a major obstacle in bridging the<br />

current skills gap.<br />

TC: Who are you looking to attract to the<br />

new training facility?<br />

It’s open to those within the industry who are<br />

looking to gain further theoretical and practical<br />

experience in a range of EWI systems and<br />

practices. Our experts are fully-equipped to<br />

ensure clients come away better informed of the<br />

processes and systems involved.<br />

TC: How easy is it for someone operating<br />

in the construction sector to diversify into<br />

EWI installation? What sort of skills will<br />

they require?<br />

CK: Anyone with a plastering skillset who wants<br />

to move from internal to the external method<br />

should be able to diversify. A bit of building<br />

knowledge and some trowel skills are a perfect<br />

base from which to branch out into EWI.<br />

TC: What are some of the challenges that<br />

contractors and installers face on EWI<br />

projects?<br />

CK: The challenge is to be as focused on the<br />

minor details as you would the major ones. I’ve<br />

seen many an EWI project fail in the hands of an<br />

experienced installer because they failed to<br />

address a seemingly minor issue.<br />

TC: How is the EWI market performing<br />

currently?<br />

CK: While it is extensively used in Europe, EWI is<br />

still a relatively little known technology in the UK<br />

but the market is growing gradually as architects,<br />

clients and homeowners start to better<br />

understand the benefits. In the mid-2010s, the<br />

market was driven almost exclusively by funding<br />

but became overstretched, and the quality of<br />

workmanship dropped as some companies saw<br />

an opportunity to make a quick buck. Now that<br />

funding has reduced to a much lower level, the<br />

market has contracted but as a consequence,<br />

quality has increased in the main.<br />

contractor working on<br />

top of a 30ft-high<br />

pitched roof without<br />

It was terrifying to<br />

watch”<br />

TC: Is the Government doing enough to<br />

incentivise the market and drive take-up<br />

of energy efficiency measures?<br />

CK: Funding is a very delicate topic. As we have<br />

seen with the Green Deal, good ideas can fall<br />

foul of bad execution and the main challenge<br />

with funded work is making sure that the work<br />

is not only completed, but completed to the<br />

right standard. We are trying to help with this<br />

by what we are doing with the academy. My<br />

personal opinion is that the Government could<br />

do more but some clear structure is required<br />

about what energy efficiency measures should<br />

be used and when. The ‘fabric first’ approach<br />

is a simple concept to understand – i.e.<br />

upgrade the thermal performance of the<br />

building so you need to put less energy in in the<br />

first place – but when there are more pressing<br />

needs such as a dilapidated boiler, and funding<br />

is limited, priorities often change.<br />

TC: How do you feel the construction<br />

sector is shaping up in 2018? Are there<br />

reasons to be positive?<br />

CK: The Government’s pledge to address the UK’s<br />

energy-deficient housing stock through subsidies<br />

and the like gives us very good reason to be<br />

positive.<br />

TC: Can you describe some of the more<br />

interesting projects or jobs you’ve worked<br />

on…<br />

CK: Our products supplied a 230mm thick render<br />

for the building of a ‘hyper-modern country<br />

pavilion’ in rural Kent. It looks as spectacular as<br />

it sounds, and we were delighted to be involved in<br />

the creation of a house that stands as a<br />

testament to modern architecture and interior<br />

comfort.<br />

TC: What about some of the funnier or<br />

perhaps alarming things you’ve seen on<br />

site?<br />

Karen Everitt at RAVATHERM UK – manufacturer of POLYFOAM XPS insulation –<br />

explains the key considerations to make during installation of ground floor insulation.<br />

During the construction on any new build or<br />

major refurbishment project, careful<br />

attention must be paid to the ground floor<br />

insulation. Understanding the correct installation<br />

methods and why a certain insulation material<br />

has been specified ensures the correct thermal<br />

efficiency of the finished building, whilst providing<br />

a durable and robust solution.<br />

The insulation market<br />

The recent shortage of polyisocyanurate (PIR)<br />

insulation has impacted many construction<br />

projects. Caused by insufficient supply of<br />

Methylene Diphenyl Diisocyanate (MDI), the main<br />

constituent of PIR, severe production delays have<br />

resulted in a market-wide shortage and extended<br />

lead times – not to mention price increases –<br />

leading to contractors and specifiers seeking<br />

viable alternative insulation products.<br />

Extruded polystyrene (XPS) insulation is one of<br />

those alternatives, and there are some key<br />

considerations for installers to make if XPS is<br />

specified. In housing projects for instance, slightly<br />

thicker XPS board will likely be required, meaning a<br />

little more digging out at the start of construction.<br />

As when using any unfamiliar construction<br />

product, it is recommended that contractors and<br />

specifiers liaise with a reputable XPS<br />

manufacturer with a knowledgeable technical<br />

team to ensure the key differences of an<br />

alternative material against the original<br />

specification can be explained.<br />

Insulation specification<br />

On some projects, contractors may need to be<br />

aware why a certain insulation product has been<br />

chosen, as factors such as the applied floor loading<br />

and the position of the installed insulation need to<br />

be taken into consideration prior to installation.<br />

Ground bearing floors, for example, can include<br />

insulation either below or above the concrete slab.<br />

Insulation installed below the slab increases the<br />

thermal capacity of the building, helping to<br />

maintain steady internal temperatures. If insulation<br />

is installed above the slab, the building responds<br />

more quickly to an intermittent heating system.<br />

Compressive strength of insulation<br />

Insulation materials used under slabs, screeds<br />

and chipboard should be capable of<br />

accommodating the applied loads with the<br />

minimum of compression. The loads in a<br />

domestic property, for example, are not likely to<br />

be significant compared to the requirements for a<br />

warehouse or factory whereby the floor will<br />

endure heavily trafficked areas on a daily basis.<br />

In housing developments, however, some<br />

circumstances such as basement constructions or<br />

swimming pools do impose greater loads, and<br />

benefit from the insulation being laid directly on the<br />

ground. Basement projects are increasingly<br />

popular in London where many people are<br />

‘building down’ due to space restrictions to build<br />

around the home.<br />

In these instances, XPS insulation really comes<br />

into its own and delivers a durable solution<br />

thanks to its compressive strength and low<br />

moisture absorption.<br />

Our floorboard range, for example, has a moisture<br />

absorption of 0.6% by volume when tested in<br />

accordance with EN 12087, and can be laid in<br />

standing water or up against wet concrete with<br />

negligible impact on the performance of the<br />

product.<br />

The material is also available with both 200 and<br />

300 kPa (Kilopascal) compressive strength –<br />

ideal for domestic projects requiring high<br />

compressive strength.<br />

The position of the insulation<br />

As briefly mentioned earlier, the position of the<br />

insulation in the floor has an influence over the<br />

thermal characteristics the floor brings to the<br />

building. Ground bearing floors can include<br />

insulation either below or above the concrete slab,<br />

and there are factors when choosing either method.<br />

Where the insulation is below a slab, screed or<br />

timber boards for example, the entire load is<br />

acting on the insulation. Point loads are spread by<br />

the layers above the insulation so that the load<br />

acting on the insulation is lower than the load<br />

applied to the floor surface.<br />

For instance in most domestic projects, an ‘over<br />

slab, under screed’ insulation solution is ideal for<br />

intermittent heating regimes, where a homeowner<br />

may only turn on the heating twice a day. In this<br />

scenario, the insulation should be installed with a<br />

vapour control layer over it. Ideally, the insulation<br />

should be positioned above the damp proof<br />

membrane. Yet in some circumstances this is not<br />

always the case. However, if installation doesn’t<br />

accord with best practice, the durable qualities of<br />

XPS insulation means it is resilient enough to still<br />

perform as expected.<br />

The versatility of XPS insulation means it’s ideal<br />

for a wide range of projects including domestic<br />

properties, and even when installed below a damp<br />

proof membrane, it can still offer its declared<br />

thermal performance, which is reassuring for<br />

specifiers and contractors considering switching<br />

specifications for future projects.<br />

Payment Issues<br />



The collapse of Carillion left thousands of suppliers and subcontractors owed money. Jackie<br />

Biswell, of Apex Roofing, examines how late payment practices have exacerbated the<br />

damage experienced by these small businesses.<br />

Small suppliers have always suffered at<br />

the hands of big businesses – but when<br />

those giants go under, the fallout can spell<br />

utter disaster.<br />

As the news spread over the past weeks of<br />

Carillion’s £1.3 billion debt, work on many<br />

construction sites across the UK came to a<br />

standstill and analysts warned that many<br />

businesses were unlikely to be paid, throwing<br />

their viability into doubt.<br />

Carillion is holding up to £800m in retention<br />

payments – the commonplace practice of holding<br />

back part of a contractor’s payment as security to<br />

ensure work is carried out.<br />

It had also failed to pay on time for a number of<br />

contracts – perpetuating the unacceptable levels<br />

of slow payer ethic commonplace in our industry.<br />

“With the aftermath of<br />

the Carillion collapse<br />

causing widespread<br />

devastation, we need<br />

to ensure that late<br />

payment is seen as<br />

totally unacceptable”<br />

All contractors would prefer to be paid within a<br />

month of invoicing but, when dealing with large<br />

companies, they are rarely in a position to argue if<br />

they don’t like the terms on offer.<br />

In the current climate, many large firms demand<br />

60-day payment terms. But almost 20% of<br />

specialist building contractors admit to paying<br />

between 60 and 90 days after invoices have been<br />

received, and some admit to pushing this beyond<br />

120 days.<br />

As a result, contractors and sub-contractors –<br />

which represent the backbone of our economy –<br />

are always battling to make ends meet.<br />

In December 2008, the Prompt Payment Code was<br />

established to help small suppliers recover the<br />

£30.2 billion owed to them by some of the UK’s<br />

largest companies.<br />

Jackie Biswell, Apex Roofing<br />

But the scheme was blasted as a failure after many<br />

firms ignored the terms and suppliers were cut out<br />

of future business dealings if they kicked up a fuss.<br />

In January, Richard Beresford, chief executive of<br />

the National Federation of Builders, released a<br />

statement saying that late payment was still a<br />

huge problem. He said: “When you factor in some<br />

main contractors imposing 120-day payment<br />

terms, £10.5 billion withheld in retention<br />

payments, and around £22 billion in annual SME<br />

turnover is paid late, it becomes clear why so<br />

many SMEs are in a precarious situation.”<br />

With the aftermath of the Carillion collapse causing<br />

widespread devastation, we need to ensure that<br />

late payment is seen as totally unacceptable. We<br />

should start by ensuring that public sector<br />

contracts are not awarded to companies known for<br />

their poor payment practices.<br />

We also need the Construction Leadership<br />

Council, which has promised to launch a<br />

construction payment charter introducing 30-day<br />

payment terms by 2025, to ensure this is<br />

monitored and enforced properly.<br />

<strong>Contractor</strong>’s Day 2018<br />

coming soon!

Van Insurance<br />



Van insurance premiums reportedly hit a three-year high in 2017, so <strong>Total</strong> <strong>Contractor</strong><br />

decided to take a look at some of the simple tips that might help contractors cut their<br />

insurance costs...<br />

In its October 2017 Van Insurance Index,<br />

Consumer Intelligence, an insurance market<br />

analyst, found that average premiums were<br />

at a three-year high of £1,214 after prices had<br />

risen 31.7% in the year to September.<br />

There are a number of reasons for this rise –<br />

an Insurance Premium Tax hike, a cut in the<br />

Ogden rate (which governs pay-outs for major<br />

personal injury claims), rising claims and<br />

fraud, the post-Brexit weak pound and the cost<br />

of repairing more technologically advanced<br />

vans.<br />

With this in mind, the natural question for most<br />

is how to cut insurance costs?<br />

“Look at the miles you<br />

drive because you<br />

should only pay for<br />

those driven, and the<br />

more you insure for,<br />

the higher the<br />

premium”<br />

1. Don’t make a claim!<br />

The most obvious solution is to not make a<br />

claim and the more years of no claims bonus<br />

(NCB) acquired, the greater the discount<br />

applied to the insurance. Only claiming for<br />

catastrophic losses that you cannot afford to<br />

cover or protecting your NCB at extra cost are<br />

the only options.<br />

2. Safety in numbers<br />

For those with more than one van, a thought<br />

might be fleet insurance; it’s easier to<br />

administrate and policyholders will benefit from<br />

the effect of multi-buy.<br />

3. Appropriate action<br />

Next comes insuring vehicles appropriately.<br />

Anything other than third party fire and theft, or<br />

third-party cover is wasted on an old van, while<br />

clearly comprehensive insurance should be<br />

78 TC MARCH 2018

taken for more valuable vehicles. Third party is<br />

the legal minimum but some form of<br />

commercial van insurance to cover either<br />

carriage of own goods (tools and materials<br />

between jobs), carriage of goods for hire or<br />

reward (for those delivering goods), or haulage<br />

(‘single’ deliveries over long distances) should<br />

be taken; always confirm if the contents are<br />

covered.<br />

4. Added extras<br />

Consider also the optional extras. Do you need<br />

breakdown cover, legal expenses insurance,<br />

trailer insurance, courtesy van cover or<br />

overseas cover?<br />

5. Mile markers<br />

Look at the miles you drive because you should<br />

only pay for those driven, and the more you<br />

insure for, the higher the premium. Be realistic<br />

– if there’s a claim, insurers can seek proof of<br />

mileage through servicing and MOT documents.<br />

6. Excess baggage<br />

Also, be careful when setting the excess. The<br />

higher the excess, the lower the premium, but<br />

set it too high and you’ll never make a claim.<br />

Ensure that the policy and claims are<br />

affordable. You could also make drivers pay the<br />

excesses, but this requires them to agree to<br />

this beforehand or you risk a claim for<br />

unauthorised deductions from wages.<br />

7. Training and gaining<br />

Is additional driver training an option to lower<br />

the odds that your insurer will have to pay out?<br />

If so, the key will be to find training that is<br />

provided by a firm approved of by your insurer.<br />

8. Monitor your progress<br />

Look also at fitting trackers and on-board<br />

cameras; these devices effectively put drivers on<br />

notice that their activities are being monitored<br />

while providing defence backup in case of a<br />

claim. Also look at offering bonuses based on the<br />

driving record of employees.<br />

Vehicles are an essential tool of any contractor’s trade, but insurance can prove costly<br />

“The higher the<br />

excess, the lower the<br />

premium, but set it too<br />

high and you’ll never<br />

make a claim”<br />

9. Size matters<br />

How big is your van? The larger the vehicle the<br />

greater the premium, so if you don’t need a<br />

large vehicle, trade it down for something<br />

smaller. Not only could it release capital, it’ll<br />

have a smaller engine and will be cheaper to<br />

run and may cost less to insure.<br />

10. Parking practice<br />

And just as with your car at night, where you<br />

keep a van after hours will have a bearing on<br />

the premium. Garaged, on a drive or behind<br />

locked gates will lower the risk and therefore<br />

the premium. By the same token, keeping the<br />

van empty at night will help reduce the risk of a<br />

claim. At the same time, consider retro-fitting<br />

security devices such as an immobiliser,<br />

tracker, alarm, or stronger door locks which<br />

have been approved by insurers.<br />

11. Modify your behaviour<br />

Lastly, vehicle modifications increase<br />

premiums so make sure you steer clear of<br />

those that boost performance or alter the<br />

aesthetics. That said, van wraps or logos<br />

appear to be cost neutral as they make a<br />

vehicle more readily identifiable and so perhaps<br />

less attractive to thieves. Also, insurers believe<br />

liveried van drivers to be more careful because<br />

they can be identified and complained about.<br />

Material Prices<br />



The issue of rising material costs is becoming an even thornier one than usual for roofing<br />

contractors according to Simon Smith, Divisional Director at Bracknell Roofing. In the first of<br />

a new, regular column, Simon says he sees a growing gulf between price rises that are<br />

justified and ones that feel like they are a step too far.<br />

Brexit, currency fluctuations and global<br />

demand for raw materials are just some of<br />

the reasons why we have seen price rises<br />

across all of the staple materials we need to<br />

construct a roof.<br />

In the last couple of years, we know that some of<br />

our suppliers have worked really hard to manage<br />

costs at their end and in turn to minimise price<br />

increases to their customers. For that they should<br />

be applauded because it demonstrates the<br />

importance placed by some on trust and positive<br />

working relations between contractors and<br />

suppliers. So, when prices have gone up, we know<br />

that these suppliers have made all reasonable<br />

endeavour to prevent this. Whilst nobody likes<br />

price rises, sometimes fair and reasonable<br />

increases are unavoidable.<br />

A double-whammy<br />

However, what does stick in the throat is the fact<br />

that there are some sections of the supply chain<br />

that are hitting us with a double-whammy. In<br />

some cases, prices are rising well above historical<br />

trends experienced over the past ten years and<br />

beyond, yet without reasonable validation of the<br />

input cost impacts driving this approach. The<br />

effect of this is compounded for contractors,<br />

particularly in slating and tiling, where the<br />

availability and service level in some product<br />

sectors has been acutely strained over an<br />

extended period, resulting in significant impact to<br />

resource and material costs.<br />

I know everyone is in business to make money but<br />

there’s a fine line between putting prices up<br />

because you have to, and putting them up to<br />

capitalise on market conditions. Of<br />

course that’s a matter of opinion,<br />

but it doesn’t sit well with me to<br />

know that we have suppliers that<br />

work with our customer base to<br />

get their products specified (fair<br />

enough) to the point of agreeing prices<br />

with them for extended periods, only to leave it to<br />

the last minute to advise us of significant price<br />

increases agreed with our customers without<br />

reference to us, which we are usually expected to<br />

start paying immediately and left to absorb the<br />

increased costs for weeks or months, until our<br />

contract next permits price renegotiation. To say<br />

this practice is unfair on contractors would be a<br />

massive understatement. This leaves me with the<br />

question: “do some manufacturers view roofing<br />

contractors as a valued customer, or merely a<br />

transactional link within the supply-chain?”<br />

Notwithstanding my previous point, our business<br />

understands that the prices of some commodities<br />

like timber and metals are much more volatile<br />

and, as much as we are able to, we factor this<br />

volatility into our forecasting and projections. We<br />

also have a good bellwether on insulation and<br />

waterproofing – but roof tiles is one product<br />

segment that confounds me.<br />

The supply of some roof tiles over recent-times<br />

has been worse than the market has seen at any<br />

other point in my 30-something years in this<br />

industry. The availability of materials such as<br />

concrete roof tiles has been severely stretched,<br />

with supply lead times reaching up to six-months<br />

in some cases. Although there appears to have<br />

been some improvement over the past few weeks,<br />

it’s too early to say whether this<br />

will be sustained and whilst I<br />

hope it will, the fact remains that<br />

contractors will continue to suffer<br />

the cost effects of this period of<br />

dysfunctional supply-chain<br />

performance for some time to come.<br />

Rock and a hard place<br />

I think the most galling part is that roofing<br />

contractors are stuck between a rock and a hard<br />

place. Yes, we can express our dissatisfaction but<br />

ultimately we have to work with these suppliers<br />

because of specifications, third party supply-chain<br />

agreements or due to the simple reality that we have<br />

projects that need completing to time and budget.<br />

What about passing on these rising costs? As<br />

most contractors will appreciate, this is a<br />

completely different ball game because in most<br />

cases our hands are tied under contractual pricing<br />

periods. We don’t have the luxury of continually<br />

renegotiating terms with builders and<br />

housebuilders. They just won’t stand for it.<br />

For us, reviewing our costs is like a military<br />

operation because we may only get one chance a<br />

year to negotiate with our customers – so every<br />

aspect of our costs are scrutinised and justified. And<br />

no matter how prepared and well organised we are,<br />

we have to work very hard to ensure we are not left<br />

to absorb the burden of the pricing strategies and<br />

performance of the roofing material supply chain.<br />
