GRP Fibreglass Flat Roofs In Welwyn Garden City
In Welwyn Garden City, GRP fibreglass is a good fit for flat roofs that get walked on or have complex details. Dormer roofs on garden city houses, extension roofs with lanterns, and small balconies all benefit from a surface laid wet that cures hard and seamless. It is equally at home on the post-war estates.

Where GRP works in Welwyn Garden City
Dormers are a feature of many original garden city homes, and their small flat tops are ideal for GRP, as the resin wraps neatly around edges. Rear extensions on post-war houses, especially those with roof lanterns, are another common job. We fit a new deck first, then lay glass fibre matting into wet polyester resin and roll it out until it bonds into a solid laminate. After curing, a pigmented topcoat seals the surface. Edge trims are bonded in for a neat finish, and an anti-slip topcoat can be added where the roof will be used for access.
Every job starts with a free survey and a written quote. Call 01438 870485 or book online.

On homes covered by the Estate Management Scheme or in the conservation area, a dormer's appearance matters. We can finish GRP in grey or lead-effect colours to suit. Any change to the outside may need consent, so we check first. GRP needs dry weather to cure. A new GRP roof comes with our 10-year guarantee.
