Material Technology: EPDM and GRP Specifications
- We install and repair the two best flat roofing systems: EPDM Rubber Roofing (e.g., Firestone RubberCover) and GRP Fibreglass Roofing (e.g., Cure It). EPDM is a highly flexible, single-ply membrane applied cold, ideal for minimising seams on large garage or extension roofs, typically finished in a dark slate grey. GRP is a liquid application that cures into a seamless, hard-wearing surface ideal for high-traffic areas or areas requiring a bespoke edge detail.
Flat Roof Configuration and Customisation
- We specialise in both Warm Roofs (insulation above the deck for maximum thermal performance) and Cold Roofs (insulation between the rafters). We ensure all new installations incorporate correct drainage falls and can integrate custom elements such as rooflights, perimeter trims in various colours, and reinforced sections for supporting air conditioning units or solar panels, tailored for homes in Norfolk, Suffolk and Cambridgeshire.
Frequently asked questions
For a standard garage roof in Norfolk or Suffolk, EPDM rubber is an excellent cost-effective choice — typically £1,500–£3,000 installed — offering flexibility and a 50-year lifespan. GRP fibreglass is harder-wearing and seamless, ideal for roof terraces or areas with foot traffic, usually starting from £2,500. We'll advise on the best system for your specific roof after a free, no-obligation survey.
A professionally installed EPDM flat roof from Norfolk Exterior Solutions is expected to last 50 years or more with minimal maintenance. GRP fibreglass systems typically offer a 25–30 year lifespan. Both systems are backed by manufacturer warranties and our 10-year workmanship guarantee, giving you complete peace of mind.
While we can patch a leaky felt roof temporarily, we strongly recommend converting to a seamless EPDM or GRP system for a permanent solution. Patching felt roofs is rarely cost-effective in the long run — a full replacement with a modern system typically costs only slightly more than repeated repairs and provides long-term protection.
Absolutely. All our flat roofing systems come with extensive manufacturer-backed material guarantees (up to 25 years on EPDM, up to 20 years on GRP) plus our own 10-year workmanship warranty. We are certified installers for leading brands including Firestone RubberCover and Cure It, ensuring your warranty remains fully valid.
Before applying GRP fibreglass, the deck must be clean, dry, and constructed from 18mm OSB3 board (or exterior-grade plywood) with all fixings countersunk and filled. We ensure any existing roof is stripped back, the deck is prepared to specification, and the weather forecast is suitable before application. Our team handles all preparation as part of the full installation service.
