What’s new for the installer in 2018?
ROOF ASSURED BY SARNAFIL
Jason Orme, Editorial Di-
rector at Future Publishing plc,
chose the Sarnafil single ply
membrane as the flat roof solu-
tion for his personal renovation
project. East Midlands based
Roof Assured by Sarnafil installer,
Manuka Roofing Ltd, installed
the membrane on this complex
but exciting and prestigious
project.
Jamie McNeill, Director, Ma-
nuka Roofing Ltd said: “We were
very pleased to work with the
homeowners on this project.
We had a few site meetings and
although there were some delays
along the way; changes of de-
sign, additional roof areas added,
revisions to drawings and neces-
sary technical alterations to suit
the changes, it was good to be
part of the renovation team and
everyone is extremely pleased
with the finished result.”
Jason took the decision to
maximise the insulation of the

’
roof and go all out on reliability
by opting for ‘a first rate cov-
ering system’ with the Sarnafil
single ply membrane flat roofing
solution. It was also important
that the membrane could not be
ripped or ruined, as an area of
first floor cladding would need
light treatment every few years,
so accessing the roof without
compromising the membrane
was key. Another factor in the
decision making process was
that the membrane has a special
lacquer coating that protects it
from air pollution.
For this project the Sarnafil
system consisted of a loose laid
polyethylene vapour control
layer, 120mm rigid foil face PIR
board, mechanically fixed (into
deck) Sarnafil single ply mem-
brane and hot air welded (no
naked flames on site) at joints
and side upstands.
The challenges for Manuka
Roofing were to work around the
actual on-site building alterations
as they progressed and they
worked closely with the builder
synchronising works with the
roof lantern and the renewal of
the existing tiled roof to blend
the new roof with the old.
Jamie adds: “The weather was
kind to us (mostly) even though
the area is pretty rural and ex-
posed. By using the mechanically
fixed system meant our reliance
on good weather for progress
wasn’t required, which is a key
benefit of the Sarnafil single ply
membrane system over other
systems which are dependent
on having good, dry weather for
installation”.
Installation took Jamie and his
team seven days in total which in-
cluded complex detailing around
upstands, rooflight and gutter
runs. Jason said: “Progress was
amazingly swift as we worked
towards getting the house weath-
ertight. It’s important to get flat
roofs right – particularly in our
situation where there’s roughly
120m2 of it to go wrong!”.
