Seamless, Hard-Wearing Flat Roofs
GRP, or glass reinforced plastic, is a fibreglass roofing system built up on site from resin and glass matting over a timber deck, then finished with a protective topcoat. The result is a hard, seamless surface that copes well with foot traffic and complex shapes.
We install and repair GRP fibreglass roofing in Bristol and Bath on extensions, dormers, balconies, porches and commercial roofs. GRP needs dry weather and careful mixing to cure properly, so installation is planned around the forecast.
Where GRP Fibreglass Roofing Works Best
GRP Fibreglass Roofing is a good choice for:
- Balconies and roof terraces
- Dormers and bay roofs
- Extensions with complex shapes
- Roofs with regular foot traffic
- Gutter linings on larger buildings
- Small commercial roofs
GRP works well where a roof is walked on or has lots of corners and upstands. For simple, larger domestic roofs, EPDM rubber is often quicker to fit, and on big commercial roofs liquid roofing or single ply may suit better. Compare them all on our flat roof repair page.
Expert Advice
Why GRP Suits Complex Roofs
Because GRP is formed on site, it can follow corners, upstands and awkward shapes without joints. Preformed trims at the edges and junctions give a neat, consistent finish, and the topcoat can be supplied in different colours. That makes GRP a strong choice for balconies, dormers and roofs with several levels.
Weather and Workmanship
GRP needs dry conditions and suitable temperatures to cure. Rain, damp boards or cold weather during installation can cause problems later, which is why jobs are planned around the forecast. The deck must be sound, dry and properly fixed, usually with OSB3 boards, because movement in the deck is the most common cause of cracking.
Repairing GRP
Hairline cracks, damaged topcoat and failed trims can usually be repaired by grinding back, re-laminating and re-coating the affected area.
Installation and Repair
How a GRP roof is installed:
- Strip the old roof and fit a new or sound deck, usually OSB3 boards.
- Apply resin and glass matting, then fit the edge trims.
- Apply the coloured topcoat in suitable weather.
- Check the finish and falls, then clear the site.
