GRP Roofing

GRP roofing, often known as fibreglass roofing, is made of glass-reinforced polyester. GRP is a roofing material that combines polyester resin with glass fibre strands for added strength. Although the resin begins as a liquid, the application of a catalyst initiates a curing process that rapidly transforms the resin into a solid.

How a GRP flat roofing system is installed.

The first step is to apply a coat of catalysed resin to a new high-quality roof decking, preferably OSB boarding. A layer of fiberglass matting is then laid followed by a second coat of resin. When the resin has fully set, the final coloured topcoat is applied to give the roof an attractive finish.

This is a diagram of the buildup of the GRP system. The decking is made of 18mm OSB
Board laid drip trims and upstands are fitted around the perimitter and once thy are secured the liquid resin and fibre glass matting are laid. Once this has hardened the coloured top coat is applied.

As you can see the great thing about GRP is that there are no seams or joints to worry about. It is a completly sealed system.
