Glass Reinforced Plastic (GRP), commonly referred to as fibreglass roofing, is a durable composite made from polyester resin reinforced with glass fibres. A typical fibreglass roofing kit contains resin, catalyst, chopped strand mat, topcoat, and all necessary tools—everything you need to create a seamless, watertight roof.
1. Exceptional Durability ✔️
A well-installed GRP roof can endure for 20–25+ years. For instance, the 35 m² Cromar Pro GRP Fibreglass Roofing Kit – 450 g from Roofing Kits Direct offers a high-quality, fire-retardant finish that resists foot traffic and impact, providing peace of mind for homeowners and tradespeople alike roofingkitsdirect.co.uk
2. Seamless Waterproof Membrane
Unlike felt or tiled systems, GRP forms a one-piece waterproof layer directly on the roof surface. No overlaps, no joints—just solid defence against rain and leaks.
3. Low Maintenance
Once cured, fibreglass roofs are essentially maintenance-free—no rewiring, no re-bonding. An annual clean and inspection are typically sufficient, saving you hassle and cost in the long run.
4. Flexible Application
GRP’s fluid resin-based application allows it to conform to any shape—flat roofs, domes, curved extensions, balconies—you name it. This adaptability makes a fibreglass roofing kit ideal for challenging projects.
5. DIY-Friendly Installation
Roofing Kits Direct offers GRP kits designed for both DIYers and professionals. Complete kits include all materials plus detailed guides, making them easy to follow. The Cromar Pro kit even supports cold-weather installation, curing effectively in lower temperatures .
