GRP Fibreglass Roof
Glass Reinforced Plastic (GRP) fibreglass is a seamless flat roof system applied as a liquid that cures to a hard, rigid surface. It offers excellent durability, a lifespan of 25–40 years, and can be shaped around details and upstands without seams. GRP is slightly more expensive than EPDM but provides a very clean, maintenance-free finish popular on high-specification extensions.
