Roofing ventilation requirements
Regardless of the scenario, roof vents must meet
UK building regulation requirements. Market
leaders in the manufacturing of roof tile vents,
such as Klober, ensure products can achieve a
high level of ventilation, potentially without the
need for a breathable membrane. Klober
universal tile vents, for example, are perfect for
ventilating roof voids, by helping to reduce the
build-up of mould growth and structural damage
in the roof space, caused by damp and poorly
ventilated roofs.
It is equally important that components are
installed correctly, as mistakes here can
potentially lead to health risks for occupants and
damage to the property. After all, the benefits of
good products can only be realised if correct
installation is followed.
Fitting Universal or In Line roof tile vents
Individual product information will inform
contractors of the correct way to install their
chosen component, but these steps can be
followed as a guide to fitting Klober’s Universal or
In Line tile vents. Suitable for roof pitches as low
as 17.5°, depending on the profile of the roof tile,
both types of tile vent can be integrated with
most concrete interlocking tiles, with possibilities
for plain tiles as well.
Installation for Universal tile vents should
be approached as follows:
1. Position vent tile in desired location and mark
area of membrane to be cut.
2. Carefully cut the marked area to the bottom
and sides, fold back the flap and secure to tiling
batten above.
3. If using an adaptor for connection it is advised
to connect prior to installation.
4. Position vent tile, nail fix to upper batten and
secure the lower butyl strip on the skirt to a clean
dry and dust free tile below.
5. Continue tiling as normal then apply cap
ensuring this is firmly clipped into place.
“With such devastating health impacts, the
importance of well-ventilated living spaces is
critical”
Meanwhile, for Klober’s In Line tile vents,
these are the steps to follow:
1. First, determine the location of the tile roof
vents on the underlay. This must be in line with
the tile below.
2. Mark a 120mm x 180mm wide rectangle on the
underlay directly below the tile batten, where the
roof vent is to be fixed.
3. Make a star-shaped cut within the rectangle
from opposite corners and fold the four tabs
upwards. The top tab will then need to be secured
to the top side of the tiling batten.
4. Place and fix the vent tile in position, ensuring
the back spigot passes through the underlay. If
using an adaptor for connection, it is advised to
connect this prior to installation.
5. A subsequent visual check should be that the
fixing lug on the underside of the vent tile is located
under the left-hand interlock of the roof tile.
6. Proceed with roof tiling in the normal manner.
A common question that tends to arise is how
many roof tile vents do contractors need? If used
to provide high level ventilation in accordance
with building regulations, then one In Line tile
vent every two metres is required. However, this
will depend on the property in question and the
purpose of the tile vent. Plus, the type of roof tile
vents selected will depend on the roof type, such
as pitched roof ventilation.
There are also plenty of helpful step-by-step
videos that installers can follow when
approaching the fitting of a roof tile to ensure
effective ventilation can be achieved.
Roofing relevancy
Many homeowners, tenants, landlords and
roofing contractors will already be familiar with
the growing prevalence of, headline hitting stories
that focus on the problems associated with
mould and damp. With such devastating health
impacts, the importance of well-ventilated living
spaces is critical.
Industry professionals can answer many of the
questions posed by cautious consumers through
the explanation of roof tile vents’ purpose, as well
as ensuring they follow best practice when fitting
the components.
