One-piece fibreglass roofing done properly

A fibreglass (GRP) roof is laid as one seamless, waterproof layer, so there are no joints or seams for rain to find. It bonds tight to the surface and cures into a hard, hard-wearing finish that shrugs off the British weather. That makes it an excellent choice for flat roofs, garage roofs, dormers and porches where you want a clean, reliable result.

GRP is also walk on strong, so it stands up to foot traffic and works beautifully for balconies and roof terraces. Because the finish is smooth and continuous, it is ideal for fitting roof lanterns and skylights, letting you flood a room with light without worrying about leaks. Our family run, CORC accredited team installs it neatly and tidily right across Surrey and South West London.
