Flat Roofing, Fibre Glass & Liquid Systems

Trace the real entry point first, then repair to match the existing system. Water can travel before it shows indoors, so a patch over the ceiling stain's position may miss the fault. We check the deck and outlets too.

A flat roof is never truly flat. Falls are typically designed around 1:40 to achieve a finished fall of about 1:80, so water runs towards outlets. The required design depends on the system and deck; sagging can reduce the finished fall.

Felt is usually cheapest up front but has the shortest life. GRP and EPDM cost more initially and generally last longer. Compare deck condition, roof details and the expected life rather than the covering price alone.

Common coverings are GRP fibreglass, EPDM rubber, liquid-applied systems, torch-on felt and single-ply membranes. They sit over a supporting deck, with insulation included where required. Follow the system links below to compare their uses.

A correctly installed GRP roof typically lasts 25+ years. We only use trade-grade materials.

Yes — GRP and liquid systems can be installed year-round provided conditions are dry. We plan installations around the weather to ensure proper curing.

Yes. We handle leak repairs, patching, full replacements and re-coats on extensions, garages, dormers and commercial buildings.

Both are excellent. Liquid systems are ideal for complex shapes, refurbishments and roofs with lots of detail; GRP is best for new, accessible flat roofs.
