GRP Fibreglass Questions Answered

Expert guidance on fibreglass roofing specifications.

GRP creates a single continuous membrane with no seams — the primary failure point of felt systems. GRP withstands thermal movement without cracking, tolerates foot traffic without damage, and maintains watertight integrity for decades. Its monolithic nature means no joints to fail, no laps to delaminate, and no torch-on risks on flammable substrates.
Yes. GRP systems are cold-applied — no torches or hot bitumen required. This eliminates fire risk, making GRP ideal for thatched properties, timber-framed buildings, occupied residential blocks, and sites with fire precautions. We use low-odour resins for interior applications and ensure adequate ventilation during cure periods.
GRP is the go-to solution for podium decks and roof terraces. Its seamless nature prevents water ingress to the structure below. We can incorporate non-slip aggregate into the topcoat for safety and detail terminations at door thresholds and balustrade posts. Walkable, durable, and waterproof.
GRP excels on complex shapes — domes, barrel vaults, curved roofs, and tight junctions. The liquid application follows any form, creating a perfectly fitted membrane. This makes GRP ideal for architectural roofs on properties in areas like Notting Hill and Mayfair where roof geometries are often non-standard.
Factory-colour topcoats typically last 15-20 years before UV degradation necessitates reapplication. The underlying matting and resin layers remain functional for 25-30+ years. Recoating involves abrasion of the chalked surface and application of a fresh topcoat — simple and cost-effective.
Annual inspection of edges, penetrations, and trim joints. Occasional cleaning with mild detergent. Topcoat renewal every 15-20 years. The inherent strength of GRP means maintenance is minimal compared to felt systems.
