One of the most popular flat roofing solutions is a GRP flat roof, or Glass Reinforced Polyester, also known as a fibreglass roof. GRP is a composite material formed by strengthening plastic with fine glass fibres.
GRP flat roofs have been used a lot longer than you might think, well over 60 years in fact, although its popularity has increased significantly in the private sector over the last few years. It is has been used in the commercial sector, marine and transport applications for a longer period.
Installations of a GRP roofing systems are simple and safe, its lifespan easily outlasts that of a felt roof.
GRP flat roofs begin with a layer of catalysed resin being applied to good quality, completely dry roof decking, ideally OSB3 wood. A layer of fibreglass mating is then laid on top followed by another layer of catalysed resin to complete the system. Once cured, a fire retardant top coat resin is then applied to completely weatherproof the roof and give it an aesthetically pleasing finish.
