Rental Unit
Single Ply Membrane
Completed
Our client had a large retail unit which totalled 15,000m2. He was looking to refurbish as large an area as possible within a fixed budget. The unit was suffering from water ingress and failing rooflights.
After speaking to a number of suppliers who all recommended a full strip back to the metal deck and the installation of a full waterproofing system at great expense he asked for the advice of NWIR Limited.
NWIR Limited immediately recommended a moisture mapping survey combined with core sampling to ascertain the condition of the roof and areas of wet or defective insulation. The survey highlighted that 90% of the roof build-up was dry and suitable for an overlay.
The majority of the trapped moisture was in the gutters. These areas were to be stripped and new insulation installed. After considering several different types of membrane taking into account the clients limited budget a new Polymeric Single Ply Membrane was used to overlay approximately 50% of the roof, this was combined with new triple skin GRP rooflights.
