GRP Fibreglass Flat Roofs In Northstowe
Some of Northstowe's newer homes have flat roofs over dormers and porches, and walk-out extensions are a popular addition across CB24. GRP, or glass-reinforced polyester, is ideal where a roof will be stepped on or has awkward corners. It forms one hard, seamless surface that is laid on site.
Options for your roof
We install and repair across all major options to suit your home and budget.

Where fibreglass makes sense near Northstowe
We recommend GRP for flat roofs that double as a small terrace, dormer roofs with tight upstands against tile, and porches with several corners. In Longstanton and Oakington it's also a good replacement for tired felt on post-war extensions where the owner wants a tougher finish. On a new deck, we lay resin and glass matting wet, roll out the air and let it cure. A coloured topcoat finishes the job and gives a durable surface that takes foot traffic.
Every job starts with a free survey and a written quote. Call 01223 398097 or book online.

If you're turning a flat roof into a usable balcony or terrace, planning permission is likely, especially on a newer estate where permitted development has been removed. We check before quoting. GRP must be laid in dry, mild weather, so we plan around the forecast. New flat roofs carry our 10-year guarantee.
