COURTESY OF VELUX
It’s fair to say most in the roofing sector will welcome in the new
year with cautious optimism at best, but thankfully a number of
contractors I’ve spoken to recently are slightly more optimistic,
with one even pointing out: “No matter how poor the wider sector
is performing, there’s always work out there.”
Perhaps that a little too simplistic – you’ve got to find that work after all,
and chances are once you do you’ll be up against more competition for
projects. But this feeling of optimism is echoed by Chic Scrimgeour of Aim
Developments in our Contractor’s Q’s on p.36. Chic stated: “Although I feel
that there are indicators that we are moving into a slow year, we remain
positive and feel that there are strong projects for us on the horizon.” Let’s
hope that’s the case across the board.
Scott Leeder of VELUX discusses the key considerations contractors should
make when working with rooflights on educational projects. See p. 44

Is price still the driving factor on construction projects? As anticipated
the overriding response was yes, but it did shine a light on some
interesting issues, with Ian Exall of Polyfoam XPS stating: “our
customers will continue to put price in the priority list but it’s no longer
just a numbers game. The whole industry is moving towards a more
forensic approach that shines the spotlight on quality, performance and
risk, and this will continue to affect purchasing decisions.” Similarly,
Richard Bishop of Wienerberger cautions against switching to cheaper
products as “a more expensive roof tile could include features that make
it easier to install than a lower quality tile, leading to a saving in labour
costs and the time taken to install.” Read the full feature on p.28.

Midland Lead is working with colleges throughout the UK.
Midland Lead says it is proud to support
seventeen colleges throughout the UK to
help develop future skills within the
construction and roofing industry.
The lead sheet manufacturer says it is fully
aware of the challenges that the sector faces
with a potential skills shortage in the future.
Recently they featured in the Parliamentary
Review where they outlined their commitment
of working to attract new talent and develop
a skilled labour force in the future.
This passion for developing new talent has
resulted in the company working with
colleges throughout the UK. Since launching
the initiative Midland Lead now support
seventeen colleges providing machine cast
lead, tools and ancillary products free of
charge. Midland Lead are also very hands on
and they send their team of experts to visit
many of the sites offering presentations
about best practice on how to handle, store
and work with lead.
Lynn Street, Sales and Marketing Manager at
Midland Lead, explained: “I have been
working within the roofing and construction
industry for twenty years and it is clear that
there is a real shortage of people choosing
this industry as a career – no matter what
age. Since working with a number of colleges
we have seen a real improvement in how
organisations are looking to recruit talent of
the future and the results are starting to
speak for themselves – but we have a long
way to go to maintain the momentum and we
are totally committed to making sure we play
a role in supporting young people.”
PREPARE FOR MORE HARSH WEATHER!
With recent long range weather forecasts
suggesting the UK could be facing the coldest
winter for almost a decade, roof systems
manufacturer Marley is urging construction
workers to get prepared for freezing winter
Bitterly cold weather, ice and shorter periods of
daylight mean there is a much greater risk of
accidents on construction sites during the winter
months. As well as the risk of slips and falls,
prolonged exposure to the cold can cause
construction workers to suffer from more colds,
bronchitis, asthma, painful joints and fatigue. In
extreme cases, workers outside for long periods,
So, how should construction workers
prepare for winter weather?
1: Make sure you are wearing the right PPE and
extra clothing suitable for the job and the
weather conditions. This usually involves using
several layers of clothing, as well as
waterproofs or wind resistant fabrics where
necessary. Also, choose water resistant
footwear, with enhanced slip resistance or ice
grips if required.
2: Wear gloves when fine manual dexterity is not
required and the temperature drops below 4°C.
3: Cold weather increases the risk of hand-arm
vibration syndrome, so keep your hands and
arms warm when using vibratory equipment
such as drills, nails guns and even hand tools,
such as hammers.
4: Choose hats that work with safety headgear
without the right protection, could even suffer
hypothermia and frostbite.
Pete Flynn, Health and Safety Advisor at Marley,
explained: “While heavy snowfall usually brings
work to a standstill, even the smallest amount of
snow or ice can create major hazards and health
risks on building sites. It is important that all
construction workers understand the hazards of
working in winter and know what precautions to
take when cold weather sets in. Builders and
sub-contractors must carry out their own
thermal risk assessments and take appropriate
action to protect their employees.”
See below for more from Marley:
and don't compromise any eye or hearing
5: Be aware of the symptoms of cold exposure
– heavy shivering, uncomfortable coldness,
numbness, aching, severe fatigue, confusion,
drowsiness and / or euphoria.
6: With reduced daylight hours, visibility can be
a problem, so wear reflective PPE.
7: Take breaks in heated areas and drink plenty
of fluids, including water and warm beverages.
8: Report any hazardous areas to the site
manager and do not put yourself at risk just to
complete a job.

goodies, To apply for one of 500 free flasks,

THE BEST ALL ALUMINIUM LANTERN ROOF
The Charles Godfrey Memorial Award for Innovation is given every
year to a product that has brought significant innovation to the
The Korniche Aluminium
Roof Lantern has been
awarded this prestigious
award for 2018.
Roger Bisby who tested the Korniche earlier
in the year commented: “The first thing
I saw was the packaging. Every builder
knows the frustration of having items arrive
on site with damage. It slows the job down
and causes hassle for the manufacturer -
and the customer. Often there is a knockon
effect because other trades are unable
to get on. With the Korniche Roof Lantern,
everything arrived in perfect condition.
The next thing is the instruction booklet,
which deserves as award on its own. A huge
amount of thought and design has gone
into this. Every stage is clearly shown with
intelligent use of colours to show you the
Then there is the engineering. It all fits
perfectly, and, when I say fits, I mean no
gaps or misalignment, and no need for
packers, shims or sealant.
The whole installation process went like a
dream and I said at the time that I couldn’t
wait until I had the chance to fit another.
It didn’t take long. Without the slightest
rush I fitted three on a roof in less than a
morning and each one was perfect. More
importantly, the customer was delighted”.
Made For Trade are delighted to have
received this award, one that stands by
the very values on which the Korniche
was conceived - to deliver to builders and
installers a product that makes life on
site easier and more cost effective, whilst
providing a beautiful, architectural lantern
look that is contemporary whilst holding
on to traditional timber style fitting any
home. FITTED IN MINUTES, GLAZED IN
SECONDS, STRONGER than any other
lantern on the market with WARMER
construction and SLIMMER profiles.
Bradley Gaunt, Managing Director says “We
have been entered for many fenestration
awards over the last couple of years and
from my point of view in this industry
we often see these awards as the usual
suspects congratulating one another on
their endeavours, in many cases winning
could easily be based on the strength of a
Call: 01642 610799 | Fax: 01642 615854 | www.korniche.co.uk
PR budget?!. So I’m over the moon with this
independent award and Roger’s comments
as it puts the product, engineering and
design centre stage and applauds the
advantages these efforts deliver above
its competitors. In 2019 Made for Trade
continue the innovation delivered in the
Korniche Lantern with a new product launch
at the FITShow which we are all very excited
There is no greater proof that a product like
Korniche has made a mark on the industry
than seeing competitors scrambling to
catch up, looking to pick up on one or two
aspects of the design to try and differentiate
their own products and claw back market
share. However, the Korniche Aluminium
Lantern has already achieved an affinity
with both trade and homeowners which
will be hard to overturn. No other lantern
has the overall winning combinations
the Korniche delivers. From quotation to
delivery in as little as five working days
for a totally bespoke product and fitting in
under 30 mins on site – Korniche remains
the obvious solution for trades looking for
a lanterns to grace their flat roof extension
projects in 2019.
You may notice that BTS has been reserved in
2018 regarding statements relating to fire testing
of rainscreen systems. While other rainscreen
manufacturers have been using BS 8414 “system
testing” as a marketing tool to sell their products,
giving clients a misleading level of confidence.
At BTS we feel this type of message conflicts with
our professional and personal ethics. If you
deviate from what a “system house” has had
tested, then the test will be invalid. The fire
performance of a ‘system’ will react differently
when materials are substituted, removed or
dimensions are changed.
So, what does that mean? If you don’t use the
exact type cp board & thickness – test void; If you
don’t use the same brand & type of breather
membrane – test void; If you don’t use the same
specification of insulation or thickness – test
void; If you don’t use the same fire barriers,
thicknesses and position parts the same – test
void; If you don’t use the same depth of helping
hands, set out centers or rail profile – test void; If
horizontal top hats or channels are introduced to
the buildup but weren’t in the test – test void; If
the panel sizes or the panel orientation is different
from the test – test void.
We agree with the principle that projects above
18m are high risk. Due to recent events Scotland
have ruled this should apply to buildings up to
11m. We would recommend going one step even
further and including other buildings with high
occupancy rates i.e. student accommodations,
schools, hospitals, and offices regardless of height.
BTS is known for being a leader in the rainscreen
industry; we don’t just follow and do as others do.
This issue of “system tests” is just another
version of fire desk top studies which, as we
know, are in the process of being banned...
To be clear, BS 8414 testing is supposed to be an
exact prototype of the building, not a rough
So, what does BTS recommend? BTS believes that
the lowest risk option for facades is to use noncombustible
If BS 8414 testing becomes unavoidable, we will
recommend to clients that a project specific BS
8414 1-2 (part 1 is on block part 2 with SFS) test
should be completed. We recommend that a test
is designed and planned identical to the buildup
on a project.
The facade manufacturing industry must play its
part to ensure that customers are fully aware and
educated in terms of BS 8414 part 1 or part 2
testing. BTS won’t sell false assurances, just to
tick a box.

On Friday 30th November, IOSH co-presented the
No Time to Lose campaign’s focus on asbestos
and distributed co-branded pocket cards for
roofers during the first annual NFRC Contractor’s

IOSH Vice-President Louise Hosking spoke about
disturbing findings from an IOSH-commissioned
survey of construction workers for the NTTL
Asbestos phase launch in April 2018.
“Nearly one in four UK construction workers
believe they may have been exposed to asbestos
fibres, placing them at higher risk of contracting
terminal cancer later in life,” said Louise.
She asked for a show of hands from the audience
to identify those who thought they might have
been exposed to asbestos in the past.
Similar to the NTTL survey, around half answered
‘yes’, which is unsettling.
Above l-r: IOSH Vice-President Louise Hosking; Kirsty Phillips

wouldn’t be clear what to do.
Louise co-presented with Gary Walpole, Health and
Safety Officer at the NFRC and Kirsty Phillips from
Gully Howard Technical, who have developed a new
asbestos awareness e-learning course for roofers.
“Over 20 tradesmen die each week from
asbestos-related diseases. We have to find new
ways of engaging more,” said Gary.
“At the No Time to Lose Asbestos launch in April
this year, we talked about Gully Howard Technical
exploring the possibilities of developing an e-
learning asbestos-awareness course we could
use with our members.
“New information and advice on avoiding contact

Kirsty Phillips, Training and Marketing Manager at

fantastic and timely opportunity this was.
“Speaking to a room full of roofing industry
professionals, it was clear they were not fully
aware of where it might be found in an image of a

significant knowledge gap we need to bridge so
people can work safely.”
“These initiatives represent a great opportunity to
show the new e-learning course and NTTL

MIND THE ROOFING SKILLS GAP
There are an estimated 32 million unemployed people in the UK, yet the skills shortage
within the construction industry continues to increase each year. Simon Hall, Training
Manager at SIG Roofing, discusses why it’s crucial to start bridging the gap.
On the whole, 2018 was a positive year for
the construction industry, with output
recovering after a slow start with new and
RMI work driving businesses forward. So, while
the UK still faces an uncertain 2019 with the
unpredictability of Brexit, the construction
industry is still expected to remain strong.
However, one thing that has remained consistent
across the sector is the lack of new skills coming
into the industry and an ageing workforce
widening the gap. When new talent is joining, there
has also been a lack of quality training available
or even time to spend away from the job to upskill.
Difficulty recruiting roofers
The roofing industry is also feeling the stretch,
with The Federation of Master Builders’ State of
the Trade Survey revealing that in the first half of
the year a third of respondents had difficulty
recruiting skilled roofers. It also revealed that the
workload for construction SMEs has been on the
rise for more than five years, which further adds
to the workload pressures faced by the industry.
While there are no quick fixes, there are
measures that can be taken to reduce the longterm
impact. Recently, the NFRC and CITB have
announced a pledge to take steps in upskilling the
workforce and are exploring new ways to attract
new talent through its RoofCERT initiative. SIG
Roofing has backed the accreditation with the
hopes that it will help diversify the sector whilst
The Government is also doing its bit to help
secure new contractors into the roofing industry.
The new apprenticeship levy launched in 2017
means businesses with a pay bill of less than £3
million per year (approximately 98% of UK
businesses) will have 90% of their
funded by the
levy. It will be
paid by those
with a pay bill
of more than £3
million, at 0.5% of
their total annual pay bill per
year. This means that affording apprenticeships is
now much more feasible for businesses of all sizes.
The new schemes combine classroom study with
time spent on site with a roofing company,
providing the practical and theoretical knowledge
required for achieving the relevant qualification.
Apprenticeships are run through colleges all over
the country in partnership with employers keen to
take on young apprentices and train them up
through their ranks. The colleges offer ongoing
support for both apprentices and employers and
are responsible for awarding the final

The young and the old
Currently it appears younger people are simply
not joining the roofing profession as, shockingly,
less than 3% of construction workers are
currently aged between 16-19 compared to over a
third being over 50. There is a job to be done to
educate young talent about the opportunities
roofing can offer to them.
One of the main benefits of getting into the
there will be no
work over the
coming years with
housebuilding on the
rise. However, in order to
entice new people into the industry, the offer
needs to be exciting, provide opportunities for
growth and above all offer good earning potential.
Alarmingly lower than industry average
Training is a key barrier as it has been reported
that, on average, only £743 per worker is being
invested in training in the roofing sector. This is
alarmingly lower than the industry average, which
comes in at £4,090 per worker per year. When
recruiting an apprentice consider formalising a
training programme for them which will show
where their career could potentially take them.
There are also wider opportunities with
manufacturers to undertake training schemes,
sometimes free of charge, which not only
enhances their knowledge but also expands your
company’s skill set.
On the whole, it may seem like a time-consuming
process bringing in and training a new member of
the team, especially when output continues to
increase. However, it is crucial that the
construction industry acts sooner rather than
later in order to future-proof the roofing sector,
but also allow businesses to grow and thrive
while the work continues to remain strong.

FAQS ON WIND UPLIFT
The experts at A. Proctor Group answer some of the
frequently asked questions on issues around wind uplift.
What is ‘wind uplift’?
Wind uplift is a force that is applied to roofs due
to wind pressure. Roofs should be designed to
resist this force.
Why is it important?
Roofing underlays play a part in this resistance
and will share the loads applied by the wind with
the primary covering (tiles, slates etc.). These
pressures can create a suction effect on the roof
that can cause a ballooning of the underlay
which, under extreme cases, can lead to slates /
tiles being dislodged. This is an issue to the longterm
durability of the roof, to health and safety of
passers-by, with potential risks increasing during
extreme weather and if lighter weight underlays
The detailing debate: overlaps? battens?
While British Standard BS 5534:2014+A2:2018
provides guidance on slating and tiling, there are
still different viewpoints on correct detailing of
roof membranes in order to mitigate the effects of
BS 5534 states: Underlay laps should be covered
by a batten and, where necessary, the lap of the
underlay adjusted to coincide with the nearest
slating or tiling batten.
When tile battens are used, it is accepted
practice to lay out the membrane so the laps fall
below a batten. If the tile gauge does not allow
this, then either the lap can be increased to
ensure it is below a batten or an additional batten
(sometimes called a “fly batten”) should be
installed to cover the lap. Many roofers consider
additional battens trip hazards and opt to
increase the depth of the lap instead, despite the
increase in membrane material costs this results
BS5534 offers further guidance stating: Laps may
also be sealed using proprietary means in

An Inspector Calls
MAKE SURE YOUR PROJECT RUNS
SMOOTHLY: 11 KEY CONSIDERATIONS
In a regular monthly column – ‘An Inspector Calls’ – Total Contractor has teamed up with the
flat roofing experts at BMI Icopal to help you achieve roofing success and avoid the
common pitfalls that can often cost you both time and money.
This month the Inspector offers up some
tips to ensure you have a successful
roofing year ahead.
A number of common issues and industry myths
have been addressed throughout last year that
hopefully offered some useful information and
guidance. As we enter 2019 and the winter period
(and the inevitable construction slow down that
follows), we thought it would be prudent to
reinforce some of that advice to help you all work
safely and ensure that projects, still in their
infancy, are prepared for the months ahead.
1. Stay safe
Wear the correct PPE at all times. Working
surfaces are naturally more slippery during this
period so ensure appropriate footwear is worn
and extra care is taken when working on roofs. Do
not put yourself at risk unnecessarily, and ensure
the appropriate risk assessments are completed
before carrying out the work.
2. Check the weather
The British weather has the ability to destroy a
project in a matter of minutes. Whilst the industry
as a whole is frequently challenged by the
weather, ignoring those forecasts for the sake of
early completion could lead to more expensive
consequences in the long term.
3. Keep materials warm and dry
The success to any project is storing those
products properly. Keep them covered, keep them
off the ground and keep them somewhere dry.
Defective materials quite simply will lead to a
Snow on the roof: Snow and frost can hide sharps and fines which could puncture the waterproofing system under foot.

4. Plan ahead
Larger projects may require phased installations,
so ensure night joints are sealed properly and
temporary protection is considered to any areas
of incomplete work.
5. Keep all working surfaces clean and
free of debris.
Snow and frost can hide sharps and fines
which could puncture the waterproofing system
under-foot. Winter light also reduces visibility
so ensure the roof is swept clean at the end of
each day, well in advance of the drawing
6. Be careful when drying out the roof
If surfaces are frozen in the morning, take
extreme care when thawing the roof out with gas
torches, refraining from any hot work if
combustible materials are present. Furthermore,
check with material manufacturers when using
salts to ensure chemical compatibility is not a
concern. Coarse salts can also damage the
waterproofing so protection boards should be
considered as a means of temporarily protecting
against both the weather and foot traffic.
7. Clean all outlets and gutters
Maintenance and housekeeping is key throughout
the winter period as leaves and moss will have
congregated around those outlets and gutters

Cover flashings are essential in protecting
upstands from water ingress. Any loose items
should be fixed and any missing areas replaced

watertight. Heavy snowfall may raise the water
level above the flashing heights and it is therefore
critical they offer the protection intended.
10. Do not use liquid compounds below 5°
Liquid applied systems require a minimum

The Big Question
IS PRICE STILL THE DRIVING FACTOR
ON CONSTRUCTION PROJECTS?
Ian Exall, National Sales Manager for
A: Fundamentally, price remains the driving factor
on construction projects, but priorities
have shifted. The focus is no longer on
specifying or purchasing the
cheapest products. The priority for
most of our customers is value for
money. They want affordable
products, but which can still perform
to high standards and are seeking
assurances through third party guarantees and
certifications such as BBA before purchasing.
Cost certainty is another key consideration which
is being fuelled by Brexit and fears of the
unknown. We are getting lots of requests for longterm
pricing for projects, especially for larger
schemes which could take two years or more to
complete. Many contractors are worried about the
risk of product and labour inflation, so want the
assurance that prices will remain stable despite
potential changes to market and / or economic
Andrew Hayward, MD, Russell Roof Tiles.
Absolutely price remains the overriding factor in the
vast majority of situations though manufacturers’
guarantees and environmental credentials are
gaining more and more importance.
Labour shortages are also a major concern for the
construction and many other industries. Currently,
a huge portion of the workforce are from the EU
and the final outcome of Brexit could ultimately
result in more red tape for those and a massive
shortage in labour on construction projects.
The other labour challenge is the aging workforce,
there are figures which suggest that over 20% of
the workforce is aged between 50-60; we’re
losing skilled workers to retirement. The problem
which we have talked about but is not being
addressed is that we are not attracting young
people to replace them. Construction and
conditions. Whilst this is understandable, it simply
moves the risk along the supply chain where
margins may be insufficient to withstand potential
At the same time, we have noticed a
big crackdown on specification
switching and so has our
distribution network. This is a
trend which follows the
recommendations in the Hackitt
Review and the push for more competency
across the construction industry.
Long-term, this will have a positive impact on our
sector as switching specified insulation during
construction can lead to inaccurate U-values and
potential non-compliance with Building
However, following the Grenfell tragedy,
minimising risk is another priority for construction
professionals and this is affecting all aspects of
the industry, including specification. As a result,
manufacturing careers are simply not appealing to
We’ve done a huge amount over the past 18
months working with schools and colleges local to
our sites – but the sectors as a whole need to
Lack of available skilled workers is a big
challenge waiting to happen and is not being
sorted! Brexit is a major concern to all businesses
at present but construction ploughs on regardless.
Within the housing sector it appears that
consumer confidence is the biggest challenge and
that more house buyers are concerned about the
uncertainty of the market and this is delaying new
home some sales.
We expect that Brexit will slow down construction
temporarily, but when taking into consideration
the rising population, immigration, people now
we are seeing some insulation specifications
being held even if there is a better product
available both in terms of cost and performance.
This suggests that roofing contractors, main
contractors and other specifiers are reluctant to
take on the responsibility of any liability that may
come with such a change.
Uncertainty won’t go away in 2019 and inevitably
that means our customers will continue to put
price in the priority list but it’s no longer just a
numbers game. The whole industry is moving
towards a more forensic approach that shines
the spotlight on quality, performance and risk,
and this will continue to affect purchasing
For manufacturers of construction products, this
underlines the ever growing need to provide
assurances, advice and support which help
contractors and specifiers make more informed
living for longer, the increased divorce rate and
homelessness, the rate of construction will
undoubtedly increase again.
Brexit will be resolved in, I suspect, a much more
orderly fashion than the current mass hysteria is
predicting, because it’s in everyone’s interest
both business and consumer alike.
Price at times can slow projects as builders look
for equivalent products at lower costs which
therefore has an impact on production planning
and stock availability. Price will still remain as the
primary driver, but quality and the standards of
products will still play a huge part.
As sales volumes grow, inventory and speed of
supply will overtake price as happened previously

Price is always a driving factor on any
construction project and it always will
be. A project with an unlimited
budget is a very rare thing, so
naturally cost will strongly affect
the choices made by the
responsible Project Manager and site
The challenge for any project team is striking the
correct balance between the cost of a build, the
time it takes to construct and the quality of the
finished result. When a client’s brief stipulates a
limited budget, strict timescale and product
specification, the project team must figure out
how best to work to these criteria without
compromising the successful completion of the
Switching to an alternative product is an easy way
to reduce costs for building materials and the
overall project. However, by choosing a less
expensive and lower quality product for budgetary
reasons, Project Managers run the risk of
compromising the quality of the whole project.
When considering a product swap,
remember that a higher quality
product with a higher price tag
might be more cost-effective than
a cheaper alternative. For example,
a more expensive roof tile could
include features that make it easier to
install than a lower quality tile, leading to a saving
in labour costs and the time taken to install.
Project teams and clients should also consider the
future lifespan of the building, as a choice to work
with lower quality building materials in a bid to
reduce costs could lead to expensive repair and
maintenance work later down the line. This could
also be said for how much a project team is
willing to invest in high quality workmanship from
contractors with the skills required and a good
Recent events have sparked fears over switching
out specified products and the liability issues this
brings, leading to a desire to deliver to the letter of
the project specification.
The simple act of switching out a product can
impact fire performance, thermal resistance or
structural strength, without the project team being
aware of the differences between products that
appear so similar. Therefore, project teams need
to be cautious of the subtlest of variations
between products when considering a product
switch and its potential implications. Architects
and contractors can establish relationships with
trusted manufacturers so they are well informed
about the products available in the market.
Although price will never cease to be a major
driving factor on construction projects, the safety of
site staff and future building users should always
be paramount. Better quality products may incur a
cost, but the cost of potential repercussions due to
an incorrectly specified product, or an attempt to
cut corners, are much greater.
Dean Weldon, National Accounts Director
While cost is undoubtedly still the biggest concern
in most construction projects, minimising
exposure to risk has become an increasingly
important factor, particularly in the public sector.
This is largely being driven by clients, such as
local authorities and housing associations, who
are looking for peace of mind and reputable
contractors and manufacturers, with a trusted
For this reason, full pitched roof systems from one
manufacturer are likely to become more widely
used, as they are invaluable when it comes to
reducing risk and managing liability. As well as
having one point of contact in case anything does
go wrong, all of the components have been
manufactured and tested to work together, offer
guaranteed compliance with British Standards
and our roof systems have the further
reassurance of a 15-year warranty.
We are also seeing housebuilders moving more
towards a roof system approach because of the
peace of mind and guarantees, however, cost and
time saving are the real driving factors in this
sector at the moment. In a pre-Brexit world,
where there is a great deal of uncertainty, people
don’t want to overspend and this is certainly
having an impact. With signs of the market
slowing down as we head towards the March
2019 deadline, some housebuilders have had to
react in the short term by reducing purchase
prices and starting to cut cost from some product
Downgrading roofing specifications can be risky,
particularly when it comes to components such as
battens and dry fix systems. It may save money in
the short term, but could prove very costly further
down the line – both in terms of finances and
reputation. For example, using a cheaper dry ridge
system will provide an immediate cost saving –
but value engineering means there could be a risk
of product failure and the added cost of repairs.

One way to cut cost from a roofing project, without
reducing quality, is to look at time-saving
products that could help to reduce the length of
the roofing programme, making significant
financial savings on labour time.

KEY QUESTIONS REGARDING
Tom Woodhouse, Site Services Manager at Marley, answers contractor questions about
Since the recovery in the housing market and
escalating skills and time pressures, there
has been a huge surge in demand for
interlocking concrete slates.
Offering a middle ground between the top and
bottom of the roofing price range, thin leading
edge, interlocking concrete slates are a quick and
affordable way to create a stunning slate effect
roof. They can be used for both new and
refurbishment projects and, unlike traditional
slates, they don’t require specialist skills and can
be installed by any roofer.
If you’re thinking about upgrading your concrete
tiles to give your roofing project a premium finish,
below we answer some frequently asked
questions about interlocking slates…
1: How much do they cost?
As a cost-effective alternative to both natural and
fibre cement slates, interlocking concrete slates
are the most economical way of achieving a slate
aesthetic. While they are a bit more expensive
than a standard flat interlocking concrete tile, it is
a relatively small difference in cost.
For a premium look interlocking concrete slate,
like our Edgemere product, the difference can be
as little as 3% extra on the total cost of a
standard domestic roof. The average cost of a reroof
is around £3,500, so you are only paying just
over £100 to upgrade from a standard tile to a
premium look slate.
2: What min pitch can they be used at?
The minimum pitch will vary according to which
type of interlocking slate you buy, but usually they
can be used at a lower pitch than natural slate.
Above: Marley offers the Edgemere interlocking concrete slate.
For example, our Edgemere slates can be used
down to a low minimum pitch of 17.5 degrees.
3: Will the tiles be accepted by planning
as a natural slate replacement?
This will depend on what type of interlocking slate
you are using and where you are installing it. In
many cases our Riven Edgemere slate, which is
designed to more closely resemble a natural
slate, is accepted by planning departments.
However, you will need to check with the local
planning office as it will depend on the proposed
There is also a new Anthracite colour in our
Edgemere range, which is designed to provide a
closer aesthetic match to both natural and fibre
cement slate. This gives you a cost-effective
easy-to-fix option when a slate appearance is
required by planning.
4: I’ve been told fibre cement slates are
too light, so can I use concrete slates to
replace a natural slate roof?
When changing a roofing material for one that is
lighter or heavier, we always recommend
consulting a structural engineer to give you
appropriate advice on load bearing. It is true that
on some refurbishment projects, fibre cement
slates may be unsuitable to replace an existing
natural slate roof. However, at around 44kg/m²,
our Edgemere concrete slates are not that
different in weight to a natural slate, so they
could be a suitable replacement but it would
depend on the structure of the building and
5: What is the coverage rate?
Interlocking slates are designed to be very quick
and easy to install, with a high coverage rate –
ours is 9.7 tiles per square metre. Like all
interlocking tiles, they should be fixed to BS 5534
recommendations, both for new build and
6: How can I install them to BS 5534
Since BS 5534 was revised in 2014, all
interlocking tiles are subject to more stringent
fixing specifications, which means there is an
element of clipping on all roofs laid in single lap
Traditionally, these clips and nails come in
separate bags and need threading together prior
to installation, which is fiddly and adds extra
labour time to the job. To save time, you can use
the SoloFix one-piece clip and nail. It’s
comparable in price to a standard aluminium
clip but can save as much as 30% on roof

MORTAR IN MODERN ROOFING
Roofing consultant and pitched roofing expert John Mercer – writing on behalf of Edilians –
talks all things mortar.
Ihave written many articles advocating the use
of dry fix products such as ridge, hip and
verge systems, with all the benefits they bring
to modern roof construction. However, we must
not forget that mortar has been used in roofing for
a very long time. Middle Eastern builders used a
material similar to concrete around 1300 BC in
coating their buildings with burnt crushed
limestone, which set hard as it reacted to gasses
in the atmosphere. Cement, as we know it today,
was patented in 1824 by Joseph Aspdin – he
called it Portland cement because it resembled
With the right mix of sand aggregate and cement,
mortar can produce a very strong
bond between building
components. But the reason
mortar fails in roofing is its
inability to cope with differential
movement between components;
even a well installed mortar-bedded
roof junction, using the correct mortar mix, can
fail very quickly if any slight movement in the
building structure takes place.
Since 2014, BS 5534 recommends that all
mortar-bedded roof components, such as ridge
tiles, hip tiles and verges, be mechanically
secured to the roof structure using fixings such as
“The reason mortar fails in roofing is its
inability to cope with differential movement

nails, screws or clips. Of course,
in many cases designers, roofers
and clients decide to use a dry fix
system and omit mortar altogether.
However, there are still many roofs where
mortar bedding is desirable for aesthetic and
traditional reasons. For example, Edilians has
some traditional clay tiles in its range, such as its
Phalempin plain tile and classic clay pantile
ranges in many popular colours, that look equally
good with mortar as well as with dry fix systems.
A great example of combining traditional mortar
bedding with mechanical fixing is the Edilians
710 clay angle ridge system; ridge and hip tiles
can be installed by mortar edge-bedding
combined with a hidden screw and clip fixing into
a ridge or hip timber. Equally, Edilians 710 ridges
can be used without mortar, with a ridge or hip
What makes a good mortar mix?
The strength and durability of mortar is
dependent on the type of sand used and even the
cleanliness of the water. Sharp sand, also
referred to as ‘rough’ or ‘coarse’ sand, tends to
give a stronger mix than soft sand; i.e. the type
used by bricklayers. The disadvantage of sharp
sand is that it is more difficult to work with and to
form smooth, neat finishes. Soft sand, often
called ‘building sand’, is easier to work with, but
it does not achieve the same strength as sharp
sand. For these reasons, BS 5534 now
recommends a mortar mix using a blend of sharp
and soft sands. In a typical three-parts sand to
one-part cement mortar mix, the sharp sand
32 TC JANUARY 2019
should make up at least one-third of the sand
content. Alternatively, a building sand can be
used that has a distribution of particle sizes
similar to blended sand. As a definition, 70% to
90% of the sand should be able to pass through
a 0.5mm sieve. There is also the difficulty of
defining exactly what sharp and soft sands are,
as they vary from region to region. For further
guidance, BS EN 13139: 2002; Annex B,
categorises sand as coarse, medium or fine and
has tables to define each type.
Hydrated and hydraulic limes are often used in
conservation and historical restoration roofing
work. Mixed with sand, the lime improves
workability and gives a softer, more porous
mortar which can be an advantage when working
with some softer building materials such as
natural stone and terracotta.
Pigments are sometimes added to colour the
mortar, though too much will reduce the mortar
strength. Generally, colour additives should not
“There are still many
roofs where mortar
bedding is desirable
for aesthetic and
exceed one part pigment to sixty parts mortar.
Proprietary admixtures are also available that
improve specific properties of the mortar. For
example, plasticizers improve the frost resistance
and workability of the mortar. These should be
used strictly in accordance with the admixture
Except for certain historically or architecturally
important old roofs, mortar should always be
supplemented with mechanical fixings when
bedding ridges, hips and verges. Baby ridges
installed on small roof details, such as porches or
bay windows up to a height of 3 metres, can be
mortar-bedded without mechanical fixings,
provided the self-weight of the ridge tiles is
sufficient to resist local wind loads.
Use the correct sand to cement mix and always
use clean, potable water. Use admixtures and
pigments in accordance with the product

TO DO LIST: QUICK QUALITY CHECK
FOR YOUR ROOFING BATTENS
SR Timber gives a quick guide to genuine roofing batten, as roofing contractors have a duty
of care to make sure that every piece of timber roofing batten used on a roof meets the
current British Standard (BS 5534:2014 + A2:2018). Here are a few things for contractors
to look out for when working with batten...
Check your delivery details
Before you check the batten, check the
paperwork. Deliveries of BS 5534-compliant
graded batten will come with documentation that
will state five things:
1. Name of the supplier
2. Origin – imported or British grown and / or
3. Graded in accordance with BS 5534
4. Batten size or sizes
5. Type of preservative and method of treatment
If deliveries of batten don’t come with
documentation, ask the supplier.
Check the markings
If the paperwork is in order, the next thing to
check is the batten for stamping. The stamping
can be on the side (edge) or the face, and there
should be five pieces of information stamped on
the side of every length of batten, giving
contractors key information.
The first and most obvious thing to say is that no
matter what colour the batten is, if there’s
nothing marked on it, then it’s very unlikely to
have been produced in accordance with the
In order from left to right, the markings are:
Q – certification such as the Q Mark, denoting
independently assessed third-party quality
assurance, shows that our grading, preservative
treatment, product marking and management
processes have all been independently audited
and verified by a good third-party body that is
UKAS accredited. Ask who supports the third
company management processes.
TX TTB-012 – TX is the sawmill identification
mark. TTB-012 is the certificate number for the Q
Mark issued by BM Trada.
GRADED BS 5534 – the batten must have been
pre-graded to the British Standard.
WPPA – the species code of the timber: WPPA
refers to pine and spruce – which is a mixed
25 x 50 – the dimensions of the batten in
millimetres. The other standard size is 25mm x
Get your tape measure out
Batten comes in two dimensions: 25 x 38mm and
25 x 50mm. The British Standard states an
allowed tolerance of +/-3mm on the width and a
tolerance on the thickness of -0/+3mm. These
dimensions are supposed to be measured when
at a ‘reference’ moisture level of 20%, but, in
reality, the 25mm thickness is the most important
one, and this will barely alter at the range of
moisture levels that are encountered in batten
production and on building sites. So, 25mm
minimum is what to look for in a good batten.
50mm and 38mm width batten offers superior
quality, as it is produced full size in both
thickness and width.
Check the size of knots
The rules on knots can be quite complicated, but
essentially, any large knots should not be bigger
than half the width of the batten, should they
appear on both sides of the face (width).
More than half
width of batten
Knots smaller than 5mm in diameter (which are
usually referred to as ‘pin knots’) may be allowed
anywhere, but knots over 5mm that appear on
the edge / thickness are not permitted to run
across the batten from edge to edge.

Having worked on many remote sites we were
equipped to deal with the environmental

shy of the challenge. We had to install a roofing
system that had the ability to withstand winds in
excess of 150mph. We worked closely with our
product manufacturers to ensure that we solved
this high wind loading, as at that time the BS
wind loading calculations did not cover this area
of the UK.
A lot of forward planning was required as all
materials, equipment and tools had to be shipped

Bonding to Roof Decks
BEST PRACTICE: BONDING TO
CONCRETE ROOF DECKS IN WINTER
By Shaun Lotay, Technical Director, Danosa.
It’s the most wonderful time of the year – a
time when the rain falls more frequently than
usual (if that’s possible) and temperatures
drop sharply. Yet, we are a hardy bunch and the
programme must go on.
However, whilst focussing hard on meeting the
programme demands may seem noble – and may
strengthen friendships with contracts managers –
the integrity of the system you are installing
should not be compromised.
For example, many waterproofing system
technologies are installed onto concrete decks
during these unfavourable conditions, with
systems accompanied by guarantees or
warranties on average of 20 years or more. With
this in mind, it is of key importance that the
system you are installing is appropriately
attached, and for that, it is important to continue
with a considered and methodical approach.
When planning to bond any product to any
structural deck, whether it be an air and vapour
control layer, the principal waterproofing system
or another component, there should first be a
bond (adhesion) test to the structural substrate.
Typically, a 500 x 500mm test square will suffice
comprising of the appropriate primer where
applicable, ensuring it has sufficient time to cure,
followed by any bonding compounds and the

product which is due to be bonded. Once the
components have fully cured, the components
can then be pulled to confirm whether an
effective bond has been achieved. Whilst some
prefer to pull the corner of their square test patch
or instead cut a triangle in the centre to pull from,
it could be argued that a more representative test
would be to ensure there is an unbonded edge of
the product so that the full product width can be
pulled when assessing the quality of the bond.
These bond tests described above, in accordance

anticipation of a
Above: A primed roof and air and vapour control layer installation.
Whilst it may seem that the most organised
approach is to schedule all materials and labour
resources before the bond tests have been
completed, there is a risk that works may proceed
without the proper checks being undertaken. We
have seen this happen when labour resources
have targets to meet, or presume that pre-checks
have already been completed by others. However,
skipping these important control checks is equally
likely when there is a collective focus to achieve
maximum productivity in anticipation of a looming
If for any reason a problem with the attachment
to a structural deck is discovered during the
installation, inevitably there is a strong pressure
to attempt to continue with the same materials
and / or primers already on site, which may not
be suitable. It could be reasonably argued that
whilst changing materials at this stage may
introduce delays, those delays are likely to be a
lot shorter (and less costly), than having to
resolve the problem post-handover.
So what are the risk conditions? Is it only in the
winter time that bond tests are required before
commencing? No. This should be standard
practise so that everyone involved can be
assured that the appropriate application method
has been determined. For those using structural
hot melt products, this practise of bond tests
before commencement of the work appears
engrained in our culture. It is commonplace to
arrive at most sites and see test patches of
structural hot melt systems accompanied with
detailed records of the tests completed. But, why
is this practise not as engrained with other
technologies? It should be standard practise
across the board.
By progressing your installation without these
bond tests it is often viewed by main contractors
that you are accepting the condition of the deck.
And they may have a point.
Beyond simply waiting for the deck to fully cure
(which is another topic in itself), here are few
other conditions to consider:
Sub 5°C Conditions: During these lowtemperature
conditions, there is a risk that surface
condensation may exist on the structural deck. This
is one of the reasons why many products advise
that they should only be applied in greater than 5°C
conditions, despite the products themselves
functioning in sub-5°C temperatures.
Screeds: Sand-cement screeds are often used for
levelling purposes or providing a suitable roof fall.
The problem is that these products are like
sponges and absorb water every time it rains.
Interestingly, whilst it may seem more expensive
on paper to consider tapered insulation, there may
be a saving on the overall project package if you’re
able to get your waterproofing completed quicker,
allowing internal works to proceed and scaffolding
and other attendances to be struck earlier.
Zero Falls (less than 1:80): A minimum fall on
your roof will ensure that it drains and BS 6229
advises that to achieve a minimum 1:80 finished
“It is important to
ensure that the deck is

fall, you should design at either 1:60 or 1:40 to
allow for tolerances during the construction
(depending on how much information is available).
However, how often do we see zero-falls designs
which are designed at zero falls, rather than say
1:80 to achieve a close to zero fall (after
tolerances)? In these conditions both the drying
time of the structural deck, and keeping the deck
dry after rainfall, are likely to be troublesome.
However, in the condition of a zero-fall design it is
likely that this problem may be further
exaggerated, due to the formation of back-falls.
In all of these conditions, it is important to ensure
that the deck is fully dried so that you are bonding
to the concrete deck itself, not a layer of water,
which is not known for its adhesive properties.

Single Ply Roofs
INSTALLING A SINGLE PLY ROOF:
WHAT YOU NEED TO KNOW...
The Technical Team at Bauder talk through the key steps to installing a single ply roof.
BS 6229 states that a minimum finished
fall at any point of 1:80 (1.25%) should
be achieved which includes any formed
internal gutters; this will reduce slip hazards and
deposition of fines leading to plant growth, as
well as minimising water ingress and damage if
there is a leak.
It is worth considering the guarantee required
on completion of the installation. If a Product &
Workmanship guarantee has been requested by
the client, then Bauder site technicians require
access throughout the period of installation to
ensure compliance with our design criteria and

Bauder’s key considerations when
installing a single ply roof:
1. Correct documentation on site
Before work commences it is important there is
a copy of the NBS specification available to all
operatives along with any tapered drawings,
technical drawings, adhesive and mechanically
fixed installation guidelines if required.
2. Air and vapour control layers
You need a self-adhesive or mechanically fastened
VCL. For polyethylene, you need the tapes (03 &
20) for sealing the joints of the VCL on the field
and upstand areas. All VCLs should extend up to,
but not beyond, the height of the insulation.
3. How is the insulation being installed?
If the insulation is adhered and the VCL is KSD Foil
or DBR then it has a foil finish; if the Insulation is
FA or FA-TE then you must use the Twin Cartridge
Insulation Adhesive. Ensure the board joints are
taped using a self-adhesive foil tape when using
Thermofol Contact Adhesive-Drum.
4. Fastener layout
This will enable you to ascertain the correct
fixing pattern for a mechanically fixed system.
5. Use the correct membrane adhesive
Refer to the adhesive suitability table in the
Bauder price list to ensure that you are using the
correct adhesive based upon the application,
membrane and substrate.
6. Thermofol PVC membrane laps should
be heat welded at a temperature of
between 450 & 500ºC
Heat welding is performed at temperatures
between 450 and 500°C and is a 3-stage
process for seams. The membrane should be
tack welded at 2m centres to assist with
tensioning and removal of any creases. A preweld
is created by performing a continuous weld
in the rear of the overlap so that an open pocket
with a width of approx. 40mm is formed for the
final weld. The final weld is created by leading
the pressure roller 20-30mm ahead of and
parallel to the 40mm weld nozzle. Indicators of a
good final weld are a strong shine next to the
weld and slight smoke build up.
7. Order accessories in advance
There is a vast array of single ply accessories
available to assist in reducing vulnerable detailing.
Pre-fabricated corners, outlets, un-reinforced
detailing membrane, lightning conductor clips etc.
8. Pre-fabricated metal and / or bar
When there is a change of direction on the roof it is
good practice that a hard angle is installed to
protect the insulation (in the case of a warm roof)
and to restrict the peel forces that are placed upon
the membrane in these locations. Pre-fabricated
metal should be employed at all exposed details
such as a drip or water check curb.
9. Carry out a weld check
Let the weld cool down sufficiently, then use a
weld tester probe. Place the probe on the weld
using medium pressure and move along the
weld. Do not use a scriber. Should capillaries or
open welds be found, carry out the necessary
Once the project is complete it is important that

LET THERE BE LIGHT: KEY
CONSIDERATIONS FOR ROOFLIGHTS
Scott Leeder, Commercial Director at VELUX Modular Skylights, looks at the key
considerations contractors should make when specifying and installing rooflights to
maximise daylight in educational facilities.
For many years, academics have carried out
a number of reports to determine the
impact that educational buildings have on a
student’s ability, attainment and aspiration.
Research conducted by Professor Peter Barrett
and his team of design experts at the University
of Salford, showed clear evidence that differences
in the physical characteristics of teaching spaces
explained 16% of the variation in learning
progress over a year.
The findings outlined in the HEAD Project (Holistic
Evidence and Design) also revealed that certain
elements, including the amount of daylight,
temperature and indoor air quality, are intrinsic to
improving learning in the classroom. The report
found that more daylight and fresh air, as part of
an optimised teaching environment, can increase
learning capacity by up to 8%.
These studies, amongst many others, have
resulted in specifiers and designers recognising
the importance of optimising the levels of daylight
and fresh air when developing a school, college or
university building. Critical to this is the amount
of glazing and rooflights or skylights which are a
very effective method of meeting daylight
Equally important is the position and orientation
of the rooflight and north facing installations are
often preferred because they provide a balanced
light source throughout the day that is not
“Equally important is
the position and
orientation of the
rooflight and north
facing installations are
affected by glare of the sun. The maximum
amount of light in a morning is provided by
installing rooflights on an east-facing roof,
whereas a west-facing installation will capture
sunlight from early afternoon onwards.
Rooflights also ensure a much more even
distribution of light compared to a vertical
window, particularly in larger commercial
structures. A window’s effective area for natural
lighting only extends a maximum of six metres
from the wall, whereas careful positioning of
rooflights can illuminate the whole area.
Quick and easy to assemble on site
Developed in collaboration with architects Foster
+ Partners, VELUX Modular Skylights feature a
minimalist design with super-slim profiles and
are fully prefabricated in a factory controlled
environment, so they are quick and easy to
assemble on site.
Fast becoming the preferred choice for
contractors and designers working on commercial
projects throughout Europe and created with both
installers and architects in mind; the striking
design of the skylights allows for more daylight
and fresh air, which is matched by their
performance and vastly improved installation.
Modern methods of construction
A good example of an education establishment
that benefits from high levels of natural light is
the new £12m University Technical College (UTC)
in Newcastle. The college specialises in IT and
Health Science courses for 14-19 year olds and
forms the latest part of the £200m Stephenson
Quarter in the city centre.

Based on the site of George Stephenson’s
Locomotive yard, where the Rocket was built in
1829, the college incorporates both a new build
element and renovation of a Grade II Listed
The existing roof on the Hawthorn building, which
had originally been fitted with basic linear slot
glazing, had fallen into disrepair and so it was
agreed that it should be replaced, while retaining as
much of the original timber structure as possible. It
was felt that maintaining the lines of the original
rooflights would enhance the internal space and
so the focus was on identifying a system that
would sit harmoniously with the roof aesthetic of
reclaimed slate and traditional lead work.
Gary Moss, Project Manager, Galliford Try, the
main contractor on site, commented:
“Refurbishing a listed building always creates
challenges, although the in-profile design and
slimline frames of the VELUX rooflights meant
that we were confident it would complement the
slate roof. We were impressed with how the
modular design of the rooflights resulted in a very
fast and efficient installation.”

rows of skylights linked together at the ridge,

frames and ridge top pieces further
complement the grey slate and leadwork.
VELUX Northlights were also installed on the
pitched roof of the grade II listed refurbishment,
again to replicate as much as possible the glazing
system used on the original warehouse building.
Over the last few years it has become
increasingly clear that the design of schools,
colleges and universities has a profound effect on
the health, wellbeing and academic attainment of
students. An integral part of creating a wellbalanced,

and natural ventilation.

NDC STEPS IT UP WITH WALK-ON
SOLUTION ON APARTMENT PROJECT
We take a look at how an Astroglaze walk-on rooflight helped transform limited outside
space in central London...
Architect Sara Bondia lived in a first-floor
apartment in central London with no outdoor
space. Right in front of her kitchen window lay the
roof of the ground-floor extension. Keen to spend
some time in the open air, Sara decided to
convert that roof into a terrace for her family. The
terrace would need to be stylish yet functional
and suited to their needs.
Sara applied for planning permission to renovate
the exterior space, incorporating new wooden
flooring and a combination of stylish glass and
wooden balustrades to preserve neighbours’
privacy. She would also replace an existing walkon
rooflight that occupied most of the terrace
Sara sought a supplier that could deliver a tailormade
rooflight that met the project’s exacting
requirements. A large walk-on solution was
needed, measuring 1550mm x 2132mm, which
would meet stringent Building Regulations.
Additionally, to maintain a flush surface with the
new wooden flooring, a minimum frame height
was required. Sara struggled to find suppliers
because it was a non-stock item. However, after
much online searching, she found NDC.
Adept at delivering bespoke solutions for a wide
variety of residential and commercial projects,
NDC supplied an Astroglaze walk-on unit for the
project in the specified size. To maintain privacy
for both Sara and her neighbours below, the
glazing was fully sandblasted and delivered with

maintenance. The textured finish also ensures

From a design perspective, a white border was
chosen around the glazing while the fixings were
delivered in a bespoke polyester powder-coated
finish of black/grey in RAL 7021.
The white border and grey / black fixings set off
the colour and texture of the wooden decking well,
with a standard black border considered too dark
and harsh, creating too much colour contrast to
be in keeping with the overall design scheme of

Regarding NDC’s involvement in the project, Sara
said: “The NDC team was extremely supportive.
As our requirements were very particular –
especially considering the size and weight of the
rooflight needed – I had a lot of questions. Due to
the large size and the resulting weight, a new
steel structure had to be created on top of the
roof as it couldn’t be supported by existing rafters
and joists. I was also struggling to find a solution
with the minimum frame size required to make
sure that there wouldn’t be a step between the
rooflight and the decked flooring. All of this had to
be taken into consideration and NDC was wellequipped
with the technical information and
know-how to answer these questions and
responded quickly to all my enquiries. The team
was proactive and very supportive, and the
quality of the solution is fantastic.”

LONE WORKING: STEPS TO
WORKING SAFELY AT HEIGHT
Matthew Bailey, Divisional Manager for Inspection and Certification at HCL Safety, explores
how to minimise risks for those working alone at height. Through the right training and
correct use of equipment, he says there are various ways to support lone workers to help
them remain safe.
The HSE defines a lone worker as someone
who works by themselves without close or
direct supervision. The number of lone
workers across the UK is on the rise. In fact, over 8
million people are estimated to be lone workers,
and not just within roles which involve work at
Is it acceptable to combine lone working with
work at height? If you are talking about the kind of
heights that call for fall arrest equipment, the
short answer from the experts is: never. However,
being alone while working at height, does not
automatically mean contractors are exposed to
new risks that they wouldn’t be in groups.
While the contract lead can mitigate the risks that
all contractors are exposed to in a given work
environment; the workers themselves have a duty
to take care of their own health and safety – as well
as of those which may be affected around them.
Before work begins at height, by law employers
need to ensure lone workers are not put at risk by
considering several factors. Key legislation that
employers need to adhere to include The Health &
Safety at Work Act 1974, as well as The
Management of Health & Safety at Work
By carrying out these steps below, you can help to
protect lone workers when working at height.
Contract leads should be looking at the level of
training needed for a worker to be able to carry
out their duties at height safely. With this, the
level of supervision required should also be
considered so that the contractor meets all
requirements for the job in hand and is
competent enough to work at height.
It is down to the lead contractor to also assess
any potential risks which may occur around
manual handling, medical stability, as well as
whether the working area itself presents a risk. It
is then important for them to take steps to
remove risks where possible and put control
measures in place to carry out the task in hand,
safely. For example, some tasks may be too
difficult for the worker to carry out alone and the
employer should therefore ensure the worker is
not left unaccompanied.
How lead contractors can identify the risks:
– Talk to their lone workers to understand what
potential risks they have identified.
– Previous incidents or near misses should be
explored so that the causes can be recognised
before any work takes place.
How lead contractors can better
understand who might be at risk:
– Consider the hazards which may affect the lone
worker and / or others around them.
– Factor in the training needed to ensure the
contractor can deal with potential hazards and
has the experience to operate equipment safely.
How an employer can reduce the risks:
– Study the likelihood of the potential risk
– Judge the level of harm that could come from
the potential risk and how this can be eliminated
– Work out the cost associated with eliminating
the potential hazard.

PROTAN BLUEPROOF – A ROOF FOR THE FUTURE
CAN YOU AFFORD TO LET
YOUR ROOF BE JUST A ROOF?
A roof represents exciting opportunities
for architects and property developers.
If you are on top of a tall building and looking out over the
urban landscape, you will see a lot of unutilised space.
Architects and property developers can no longer afford to
use the roof just to keep the rain and snow out and protect
Using the roof for other functions creates additional values.
These values not only allow for increased profits, but also
add value to society at large and for the people living in
and around these buildings.
The roof can be a place where people can spend recreational
time, grow flowers and encourage wildlife. The roof can
also be utilised to solve other tasks that could be profitable
for the building project, such as generating electricity with
solar panels or taking control of heavy rainfall.
Protan has developed a unique BlueProof roofing solution
to avoid creating dead space on top of a building, enabling
use that space for water attenuation. That is both smart
and sustainable. The BlueProof system works equally well
for new buildings and refurbishment projects, and can be
combined with recreational areas, eco-friendly features
and energy production.

The purpose of a risk assessment is to take
measures to reduce and control risks – this is
required by law.
The aim of a risk assessment is to:
• Identify the work task.
• Identify any hazards.
• Highlight threats posed to others.
• Identify what control method(s) are to be used.
• Record findings.
• Overall, reduce and control the level of

Dependent on the findings there may be a need to
review and revise the risk assessment.
Control measures could include:
• Are the correct tools / equipment available?
• What PPE is needed?
• Are there enough people carrying out the work?
• What are the potential risks and how can they
best be mitigated?
• How should the job best be carried out?
• Is there use of any of controlled substances?
• Is a COSH assessment needed?
• Will there be any manual handling?
• Is there enough time to get the job done safely?
• Is the work being carried out in the best order?
• What precautions are needed?

There is also
aspect to think
completing a risk
assessment as conditions on a
site change regularly. For example,
surfaces can become slippery due to a change in
weather and external factors therefore need to be
a key consideration.
Lone working isn’t a case of getting the right
training and carrying out a risk assessment
before being left to work completely alone.
Keeping the contractor safe requires more
communication which may include:
• Scheduled visits or contact with them by
phone, radio or email.
• Manual / operated warning devices which can
be used to trigger an alert if a signal is not
received from the lone worker in a certain
• Monitoring of contractors to check they are
following the right working procedures.
It is important to consider the level of experience
of the contractor and what additional training
should be undertaken to enable them to work
alone effectively. Training is designed to change
perceptions and improve standards – something
which is especially important when lone working
at height where the risks can be very high.
Training is a crucial part of lone working at height
as there is usually very limited supervision. Lone
workers should be trained in how to carry out a
risk assessment, working at height, rescue at
height as well as manual handling. Training is

What’s more, while
other contractors may be able
to ask more experienced colleagues for
support and guidance on a task, lone workers are
unable to do so. Extra training may be needed in
situations like this so that contractors fully

There are training providers out there that will
help deliver thorough training to all participants,

EPDM Lake Project
AN INTERESTING USE OF EPDM
Andrew Cooper, Lining Sales Manager at Firestone Building Products, discusses the lake
refurbishment and remodelling project at Weald & Downland Living Museum.
Weald & Downland Living Museum is a
collection of more than 50 ‘rescued’
rural buildings arranged in a 40 acre
landscaped setting near Chichester.
Amongst the Museum’s attractions is a working
flour mill, operated with the aid of a waterwheel
and a large man-made lake. When the Museum
decided to construct a new Visitor Centre, it was
clear that there was an opportunity to enhance
the lake at the same time, leading to a project to
remodel the lake, reduce its depth and replace
the existing lining system using an EPDM
(ethylene propylene diene monomer) rubber
The lake was built when the Museum first opened
in 1970 and the original lake lining system had
reached the end of its design life. Seepage due to
the failed lining had forced the Museum to top up
the lake using water extracted from bore holes.
Specialist contractor Fairwater, was contracted to
deliver the lake refurbishment and began by
draining the lake into a lower natural pond and
removing all silt and organic material. The
contractor’s team then removed the failed liner
and remodelled the existing lake, reducing the
depth from approximately four metres to around
two and a half meters, with the materials
excavated during remodelling works used as

Flexible and robust
Although the internal lake substrate had been
compacted to ensure a smooth, solid base, it was
vital to protect the lining from any damage, so the
contractor began by laying a 250g/m2 non-woven
polyester geotextile onto the prepared surface.
The lining element of the project required careful
configuration of the EPDM lining, which was taken
from extra wide rolls to optimise use of the
material and reduce on-site seaming.
While the large size of the EPDM membrane
supplied ensured minimal joints for the main
lake area, the more structured space of the mill
chase required increased detailing. For all joints,
sections of membrane were overlapped by 50mm
and sealed using the recommended Splice Tape
for the system. Stone walls were then built up the
vertical surfaces of the mill chase to completely
obscure the lining.
There was also a requirement to conceal the
lining around the margins of the lake itself to
combine the functionality of the new membrane
with the natural appearance of a lake and enable
reed beds to become established. The contractor
installed a second layer of geotextile membrane
around the margin of the lake, taking it beneath
the level of the waterline. This was then covered
with a layer of clay to protect and obscure the
lining material, helping to create the illusion and

habitat conditions of a natural lake.
For the areas of the lake below the terraces, the
lining installer worked with the main contractor to
enable the metal terrace supports to be anchored
to the concrete footings. This involved making
precision penetrations in the membrane to allow
the supports to be secured in place before
resealing the lining using a self-curing EPDM
rubber strip designed specifically for use on
irregular details. This was adhered around the
interface between the horizontal surface of the
lake lining and the vertical terrace supports,
encapsulating the join with a robust and

years but the track record of EPDM lining systems
suggests that this could be significantly longer.
The official unveiling of the scheme and opening of
the Visitor Centre was presided over by Downton

Museum, Hugh Bonneville, continuing the theme
of connecting people and history through the
buildings and people of different periods.

PROTECTION FOR UNI ROOF
The historic buildings of St Malachy’s College in Belfast have been fitted with an added layer of protection in the form of
Roofshield providing a pitched roof underlay, which is both air and vapour permeable.
The College, a Catholic Grammar School for boys, was opened on St Malachy’s Day 3rd November 1833. A major refurbishment
project to preserve the heritage of the buildings was led by Belfast-based Gregory Architects, with Derryleckagh Contracts of
Newry appointed as the roofing contractor for the project. Gregory Architects specified Roofshield for the roof refurbishment. The
roof structures of historic buildings can be complex in nature and demand careful consideration of moisture management and condensation control. Many
vapour permeable underlays use an airtight VP film layer to achieve their performance rather like a Gore-Tex jacket. While water resistant, they cannot
completely prevent condensation within the roof space; meaning additional ventilation has to be introduced in order to allow air to circulate.
Roofshield’s patented air permeable structure allows high levels of airflow, in addition to the transport of moisture vapour, making the formation of
condensation in the roof space virtually impossible and will still perform in conditions in which airtight alternatives will not. There is also no requirement for a
separate vapour control layer. The high performance of Roofshield, backed by two BBA Certificates & LABC / LABSS, has been successfully used in preserving
and protecting the fabric of a wide range of historic and listed buildings for more than 21 years. www.proctorgroup.com

IT’S TIME TO WORK TOGETHER
Adrian Storey, General Manager at Horbury Facades, looks at the low level of façade
inspections taking place within the private sector and explains why he feels it is
important for contractors and building owners to work together to carry out these checks
as soon as possible.
It is safe to say that events over the past 18
months have prompted almost everyone to
consider the safety of the UK’s buildings,
particularly multi-occupancy structures.
Improving the levels of safety within these
developments, especially in terms of fire risk, has
been a top priority for public sector organisations.
As such, many buildings up and down the
country, including hospitals and residential
blocks, have been undergoing thorough
inspections both inside and out to ensure they are
as safe as can be.
However, in some cases, particularly in private
housing and commercial buildings, landlords are
failing to carry out these reviews as a matter of
urgency, and as such could be putting the safety
of occupants and passers-by at risk.
In fact, James Brokenshire, the Communities
Secretary, has said that private sector landlords
have a ‘moral imperative’ to remove flammable
cladding, with the government considering
enforcement, which could result in owners being
‘fined or barred from accessing other government
schemes if they do not obey’.
The Guardian reported on Mr Brokenshire’s letter
to around 60 developers and building owners
‘including some of the UK’s biggest property
firms’, in which he explained ‘actions they must
take to avoid penalties’ concerning removing
Assessing the risk
Currently the Regulatory Reform (Fire Safety)
Order states that fire risk assessments for highrise
residential buildings must be carried out
‘regularly’. It is recommended that the
responsible person ensures these are undertaken
at least annually and when any significant
alterations are made to the building.
Many new and refurbished
buildings now feature exterior
cladding, therefore landlords
may not be aware that it is
not always possible to
establish the full fire
resistance of the building
visually. Contractors should
therefore be working closely with building
owners and specifiers to advise that an indepth
inspection is carried out quickly
and as soon as possible.
It is also worth communicating
that a site survey not only tests
for fire safety but will also ensure
early detection of any defects and

Polterm Max Plus is a non-combustible 1200 x 600mm stone mineral wool slab, which delivers excellent thermal and
acoustic performance, while achieving the best attainable A1 Euroclass fire classification according to EN 13501-1.
With a thermal conductivity of 0.035W/mK, Isover’s new range will help reduce heat loss within a building; the slabs can be tightly butted together, while the
inner face accommodates substrate irregularities, to maximise the thermal performance. In addition to its thermal performance, Polterm Max Plus will also
improve the acoustic performance of the external envelope, reducing the airborne noise from aircraft, vehicles, trains and weather. Polterm Max Plus contains
a water repellent additive to protect against moisture ingress during installation.
The black glass veil on the external facing side of the insulation contributes to the aesthetics of the installation, as it prevents unwanted sightings of the
insulation from behind a ventilated rainscreen façade system. Stuart Dumbarton, Isover, commented: “The launch of Polterm Max Plus demonstrates our

Insulation & Fabric First
VENTILATION & OVERHEATING ISSUES
High performance insulation and the fabric first approach holds the key to getting a building
airtight and meeting energy efficiency demands, but the IMA asks is enough attention being
paid to other aspects, including ventilation, heating, detailing and the quality of the installation?
Overheating and poor air quality has
received wide and often simplistic
coverage in the press, including even
suggestions of deaths caused by overheating.
This has led some to erroneously put the blame
on insulation. However, despite the fact that
overheating can be a problem, particularly in poorly
ventilated loft spaces, it is a more complex issue
than insulation alone, and well-installed insulation
could even help reduce overheating if a wholehouse
approach to building design is employed.
As is so often the case, an intelligent solution to
the problem will need to consider a range of
factors. It is a given that the more insulation you
have, the heat from solar gain will last longer, and
if you don’t have adequate ventilation and design
to limit internal and external heat gains, then of
course that heat will stay in the building. But it’s
not the fault of the insulation. Blaming insulation
for doing its job is a bit like blaming an oven for
global warming if someone leaves the door open.
An under-ventilated property can experience
condensation issues and problems with air
quality. An over-ventilated dwelling is usually less
efficient, as lost heated air is replaced with colder
unheated air from outside.
A good ventilation system will ensure the right
amount of air moves consistently through the
house and is vital in kitchens and bathrooms.
Excessive moisture in the air can lead to
condensation and mould growth where it
condenses on colder surfaces, not just in the
bathroom itself but throughout the rest of the
house. A ventilation system will remove and
dilute the odours and pollutants that can
accumulate so that the indoor environment
remains healthy for building occupants.
Often the only form of ventilation in older homes
is through natural leakage such as around doors
and windows, or by opening windows, but these
are uncontrolled with either too much, or too little,
ventilation. When a building is retrofitted with
insulation, the airtightness of a building may
increase through sealing up uncontrolled
ventilation pathways, so it is essential that
alongside any changes to the building fabric, an
adequate ventilation strategy be considered.
A 2016 study by The Fraunhofer Institute for
Building Physics IBP looking at mould and
dampness in European homes, concluded that
“Enabling easy natural, automated or mechanical
demand-related ventilation in buildings helps
prevent development of damp and mould.”
Mould-related damage was noted in the report as
being frequent in Germany (10% of building
damage being mould related), but levels were
noted as being better (lower) for modernised
buildings. The report noted that for those
modernised buildings (after 1995) 35% of damage
occurs due to insufficient thermal insulation; 33%
due to insufficient ventilation; 22% due to
defective installations and trapped moisture and
10% due to problems in sanitary / other areas.
So from the report, it is clear that adequate
insulation is the most important factor to help
reduce moisture problems, but close behind is
adequate ventilation provision.
But it is not only insulation and ventilation; house
design means taking the time on the details. For
example, ensuring junctions are appropriately
designed and constructed, as this makes a
significant contribution to reducing heat loss.
Thermal bridges occur at breaks in insulation at
junctions and openings causing heat loss which
ultimately leads to a drop in internal temperature
and an increased demand for heating. This can
increase the risk of surface condensation and
Good design and workmanship necessitates a
proper level of quality assurance throughout design
and construction and good detailing is particularly
important for new-build and retrofit alike.
The Government’s Fabric Energy Efficiency
Standard (FEES) has grappled with the issue and

Company Focus: IKO
INVESTING FOR A CHANGING FUTURE
New management has allowed for strategic alterations to IKO’s operating structure and below,
Anthony Carlyle, the new Managing Director at IKO, outlines the changes at the company and
the outlook for 2019.
Last year was an exceptionally positive year
for IKO, full of growth and investment into
vital areas of the business. The most
obvious sign of this investment was the opening
of our brand new PIR insulation factory at
Alconbury, Cambridgeshire, filling what many
customers saw as the gap in our overall offer.
This facility becomes IKO’s third insulation factory
in Europe, and the UK was selected as an
attractive place to invest thanks to the core
strength of the UK business.
However, we have seen substantial growth in all
business areas, from IKO Polymeric out of Clay
Cross, Chesterfield – now exporting to more than
20 countries in Europe – to hot melt and mastic
asphalt at Grangemill, Derbyshire where we are
seeing some great innovations in terms of both
new products and manufacturing efficiency.
Alongside major changes, there have also been
numerous examples – even just since I’ve been
in this role – where we’ve been asked to find a
solution for customers which involves putting
together a creative combination of our product
offering. With IKO’s resources, we should always
have a solution and we need to start thinking
outside the box more.
Over the years, I think it’s fair to say that IKO as a
business has been a little bit fractured. Much of
this comes down to having such a diverse product
offer which serves a very wide range of customers
who may appear to have little in common.
We need to start operating our business in a more
joined-up way and changes introduced over the
last six months have provided progressive steps
to ensure that IKO is in the best position for 2019
and beyond. We are restructuring in the true

Insulation Updates For further info on all these roofing updates and more, visit www.total-contractor.co.uk
Knauf Insulation has launched its new Solutions Guide to make specifying the right insulation for every
application quicker and easier than ever before.
The guide features the company’s extensive range of non-combustible, high-performance insulation ordered by
application. This means customers, including architects and specifiers, can identify which products are best suited
for roofs, walls, floors and fire protection. Product data detailing features and benefits are then listed in full at the
back of the Solutions Guide.
The Solutions Guide also includes information
about Knauf Insulation’s sustainability credentials.
Steve Smith, Knauf Insulation, said: “It has never been so important for architects and specifiers to specify the right insulation for the project. As the only
manufacturer of both Glass and Rock Mineral Wool, we are uniquely placed to recommend the best insulation solution for each application. Our new Solutions
Guide is designed to showcase which of our products is best suited for each of the different build elements of their designs. Within the product section, we
have added a handy dial rating system. This allows readers to see at a glance each product’s thermal and acoustic performance, Euroclass Reaction to Fire
classification and BRE Green Guide rating for sustainability.” www.knaufinsulation.co.uk/solutions-guide

Isover is rolling out new packaging for key product families found within its range.
The new design has been created to improve product identification and make selecting and picking easier for

backdrop, the new packaging is colour-coded by application, using a strong palette of five colours to help
customers find what they need faster. Órla Whelan, Marketing Director, said: “These changes are in response to
customer feedback; our priority was to overcome the issues customers were facing in relation to the packaging.
The updated design does just that.” www.isover.co.uk

PROTECTING YOUR BUSINESS
AGAINST CUSTOMER DEFAULT
Poor payment practices have plagued construction for decades and, unfortunately, will
continue to do so for many years to come. But what can contractors – who are often caught
in the middle – do to protect themselves?
2018 was not great for some of the UK’s
best-known businesses. Firms once
thought of as unassailable went out of
business; Carillion, Maplin and Toys R Us were all
high-profile names that faded.
It’s not hard to find examples of construction
firms that have failed – Galliford Try lodged a
counter-claim over a payment of nearly £3.5m
allegedly owed to a collapsed subcontractor, and
four Lagan Construction firms were put into
administration with 200 jobs threatened.
Mid November (2018) the BBC reported concerns
over construction and facilities management
company Interserve. One source told the BBC
that: "we could be looking at another Carillion. I
don't see how they can raise the £500m or so
needed." Other sources close to the company
denied the firm was close to bankruptcy and said
it was set to ask new investors for more capital.
Either way there are worries for those linked to
Although these failures will have had an
immediate impact on the employees of those
companies, a ripple financial effect will inevitably
also have been felt by the thousands of
businesses that contracted with them, whether
as suppliers, contractors or sub-contractors.
So how can businesses best protect themselves
against the financial failure of one of their

Recoveries at law firm VWV, knows that it's not
always apparent at the start of a business
“It's not always
apparent at the start of
a business relationship
whether a customer is

sound. This is why he says it's always prudent to

when entering into large or longstanding

However, even in a business that appears

quickly. Carillion is a perfect example. It’s 2016

before tax of £178m. But by April 2017 a new
Financial Director had found at least £170m
worth of accounting problems and the 2016
accounts had to restated. The rest is history.
Husband says that “because things can change
so quickly, the single most important thing to
have in place is an effective contract which
operates to protect your business from the
beginning of the legal relationship. There are
terms which can protect your business.”
He outlines them:
Effective payment terms: Is your bargaining
position strong enough to require payment before
delivery of your product or service, either in whole
or in part? If not, ensure that your credit terms
are short and are effectively policed.
He asks: “What are your rights in the event of
non-payment? Charging interest for late payment
should be a given, but what about your right to
terminate the contract or withhold services or
Contract termination: In what circumstances
can you bring the legal relationship to an end? As
well as for non-payment or breach of the
contract, Husband advises that “provision should
be made for other insolvency events, such as the
liquidation or administration of the customer or
even upon the preliminary steps taken towards
those insolvency events.”
Retention of title (ROT): perhaps most
importantly for suppliers of goods – less so for a
jobbing roofer, Husband says firms should ensure
that they have a clause by which they retain
ownership in the goods they supply until they
have been paid: “ROT clauses have long been
included in standard contractual terms and can
operate effectively to enable you to recover your
goods provided that they are properly
incorporated, worded right and that you enforce
those rights promptly in the event of nonpayment.”
There is a catch here though – ROT
only applies to goods, in a construction context,
that haven’t been used.
“All of these terms,” says Husband “are very
much a starting point, but it is also worth
remembering that you need to ensure that it is
your contractual terms that prevail, as a
customer's terms will invariably favour them.”
He says that which terms apply is not always
obvious, particularly where parties each purport
to operate on their standard terms (perhaps
64 TC JANUARY 2019
printed on purchase orders or invoices), so
having a signed agreement is always best. It’s
important to also note that changes to insolvency
legislation and processes mean that many older
contracts are often simply not fit for purpose, so
ensure that your terms are regularly reviewed.
“It’s important to also note that changes to
insolvency legislation and processes mean
that many older contracts are often simply not
fit for purpose”
As Husband can testify, it's rare for a customer to
fail without there being a number of warning
signs which would enable you to take preemptive
steps to improve or protect your position.
“Typical warning signs might include, most
obviously, slow payment or requests to extend
payment terms; unusual requests for price
reductions or discounts; a delay in filing accounts
or accounts that include a qualified report from
auditors; a change of accountants or auditors; the
resignation of directors; an increase in unfounded
complaints about the goods or services that you
provide; and market gossip.”
He says that keeping alert to these kinds of signs
will mean that you can act quickly to protect your
Of course, there is a limit to what can be
achieved in documentation, and if practicable any
party entering into a commercial contract should
ensure that a proper credit control system is in
place. From Husband’s point of view, “where the
sub-contractor or supplier has concerns as to
the financial position of the company it should
also consider reducing the period and / or
amount of credit allowed, obtaining alternative
forms of security (for example a bank guarantee
or letter of credit) and taking out credit
He also says that it is just as important to act
promptly to enforce your contractual rights “as
when a company goes into compulsory liquidation
or administration, any existing legal proceedings
are suspended, and a creditor cannot begin new
legal proceedings against the company unless it
has permission to do so from the court.”
However, even when faced with this, some
contractual rights can still be enforced without
needing to start court proceedings. For example, if
you have taken security to secure a debt, you will
stand first in line to recover any monies out of the
Offering a crumb of comfort, Husband notes that
if there are mutual debts owed between you and
the insolvent company, these will be
automatically set off in either a liquidation or
administration. This will mean that any monies
you owe can be set off in full rather than you only
receive a small dividend.
And lastly, and another point of note according to
Husband, “the ROT rights mentioned earlier will
survive insolvency, meaning that you will retain
ownership of your goods and be entitled to
recover them. If a liquidator or administrator sells
those goods, he or she can be personally liable to
compensate you.” However, Husband adds that
insolvency practitioners will scrutinise such ROT
clauses very carefully, so it is important to get
robust professional advice when faced with this
situation to maximise your prospects of a

HANDLING “DIFFICULT” CUSTOMERS
Successful businesses don’t just sell products and services; it’s often how they handle
customer relationships that differentiate them from their rivals. So what happens when a
customer is difficult to please? Industry expert Jackie Biswell explains how she boosts her
brand through respect, recognition and resolve.
We have all heard the expression
“customer is king”; and it is certainly
true that for any business – products
and services – your relationship with your
customer is your single biggest asset.
Concentrating on building successful
relationships creates loyalty, customer retention
and word of mouth recommendation.
But every now and then you come across
someone who is dissatisfied and who continues
to challenge you as the relationship progresses.
From picky people to know it alls, egocentrics to
fault finders and constant complainers to those
who feel they have been wronged, how you
interact with these individuals can have a lasting
impact on your business. So how do you handle
Understanding the problem

The first thing to do when dealing with a
demanding or angry customer is to listen.
This will help you understand the extent of the
problem and give you time to provide an
appropriate response. By listening, you also have
the opportunity to build trust.
The next thing to do is to show empathy.
It’s highly unlikely that you are the object of the
customer's anger. You are just getting the brunt
of it. So try to put yourself in the customer’s
shoes and see the situation from their
Try and solve the problem. Negotiation will allow
you to reach a solution where everyone is happy.
Be your brand
The way you handle customers says a lot about
your brand. So it is important to train your staff to
manage interactions in a consistent way.
In many businesses – and certainly in the world
of roofing – the typical customer knows very little
about the product he or she is buying.
This means that there is potential for difficulties
