About Sutton
Sutton town centre is surrounded by established residential streets of 1930s and post-war family housing. Common work: full re-roofs on ageing 1930s semis, garage roof replacements, and ongoing maintenance for local landlords.
What we offer in Sutton
GRP (Glass Reinforced Polyester) fibreglass is a cold-applied liquid system that cures to form a completely seamless, hard-wearing roof surface. It's the premium choice for walkable flat roofs like balconies and terraces.
What is GRP fibreglass roofing?
A two-part system applied cold directly to an OSB deck:
- Resin and mat layer — chopped strand glass mat saturated with polyester resin, applied by hand
- Topcoat — pigmented, UV-resistant, wear-resistant finish
The system cures chemically to form a fully-bonded, seamless surface with no joints or weak points.
Where GRP excels
- Walkable surfaces — balconies, terraces, roof gardens, step-out areas
- Complex shapes — valleys, upstands, intricate details
- Premium installations — when you want the best finish possible
- Colour matching — topcoat available in any RAL colour
Where GRP isn't ideal
- Large simple roofs where EPDM is more cost-effective
- Garages and outbuildings where budget matters more than finish
Installation process
- Strip existing roof covering
- Inspect and repair deck — must be 18mm OSB or plywood in good condition
- Install insulation if needed (warm roof construction)
- Apply resin and mat to upstands, edges and details
- Apply main field of resin and mat
- Apply coloured topcoat (with optional non-slip aggregate)
- Cure time: 1-2 hours per coat, walkable same day
- Register 25-year manufacturer warranty
Anti-slip options
For balconies and terraces we can broadcast fine quartz aggregate into the topcoat to create a Class 3 anti-slip surface — meets building regulations for outdoor walkable surfaces.
Warranties
- Material warranty: 25 years (with approved installer scheme)
- Expected service life: 25-30+ years
- Workmanship warranty: 10 years from us
