GRP Fibreglass Flat Roof Installation & Replacement in South Lincolnshire, Cambridgeshire and West Norfolk
At The Roofing Group, we specialise in GRP fibreglass flat roofing. Whether you’re installing a new roof or replacing an old one, we offer a durable, seamless solution designed to withstand the demands of British weather — year after year.
Why choose GRP fibreglass flat roofing?
GRP (Glass Reinforced Polyester) is a tough yet lightweight material that’s ideal for flat roofs. It’s applied in layers using fibreglass matting and resin to create a single, watertight membrane with no joins or seams — making it far more reliable than older felt or asphalt systems.
Long-lasting performance – A well-installed GRP roof can last 20 to 30 years, making it an excellent long-term investment for your home or business.
Seamless protection – With no seams or joints, GRP dramatically reduces the risk of leaks, which are common in traditional flat roofs.
Lightweight structure – GRP adds very little weight, making it suitable for everything from garages and extensions to balconies and dormers.
Built for British weather – GRP is fully resistant to UV rays, rain, frost and even fire, offering year-round protection with no compromise.
Low maintenance – Once installed, GRP requires minimal upkeep. No annual patch-ups, no moss issues — just a clean, solid finish that stays watertight.
