What is GRP Fibreglass Roofing?
GRP (Glass Reinforced Plastic) roofing, also known as fibreglass roofing, is a high-performance flat roofing system that creates a completely seamless, watertight finish. The system uses layers of glass fibre matting laminated with liquid resin to form a rock-hard surface.
Unlike rubber membranes (EPDM) which have seams that need welding, GRP creates a single continuous surface with no joints or weak points. The result is an incredibly durable, impact-resistant roof that can handle foot traffic and extreme weather conditions.
We install GRP systems using premium resins and fibre matting, with all edges and penetrations (pipes, vents, skylights) seamlessly integrated into the main roof surface. The finish can be left natural or topcoated in a range of colours to match your property.
