GRP Fibreglass Roofing
Seamless, strong fibreglass roofing — ideal for balconies, walkways, and flat roofs.
GRP (Glass Reinforced Polyester) creates a seamless, rigid shell over your flat roof. Unlike sheet membranes, GRP has no joints or laps — it's applied as a liquid and sets to form a continuous waterproof surface.
GRP is particularly strong and can be walked on without damage, making it ideal for balconies, roof terraces, and areas that need regular access. It can be finished in any colour and provides a clean, attractive appearance.
We apply GRP using the resin and mat system, building up layers to create a strong, durable finish. Every detail — upstands, drip edges, outlets — is formed as part of the continuous shell, eliminating weak points.

Frequently Asked Questions
Can I walk on a GRP roof?
Yes. GRP is rigid and strong enough for regular foot traffic. We can add anti-slip aggregate to the finish for safety.
How does GRP compare to EPDM?
GRP is rigid and walkable; EPDM is flexible and self-healing. GRP suits balconies and accessible roofs. EPDM suits standard flat roofs. Both last 20+ years.
What colours are available?
Any colour. The topcoat is mixed to your specification. Grey is most popular, but we can match any RAL colour.
