Flat Roofing
Flat roofing has moved on from the old felt-and-bitumen approach. Many roofers now use EPDM rubber, GRP fibreglass or single-ply membrane systems, which are generally longer-lasting than traditional felt. Flat roofs typically last around 15 to 30 years depending on the material, installation and maintenance, and suit extensions, garages, dormers and contemporary designs where a pitched roof is not practical.
Why Choose Flat Roofing?
- Suits extensions, garages, dormers and outbuildings
- EPDM and GRP are generally longer-lasting than traditional felt
- Seamless or large-sheet systems mean fewer joints
- Can take roof lanterns and skylights
- Usually quicker to replace than a pitched roof

Frequently Asked Questions
Which flat roof system is best — EPDM or GRP?
Both are widely used. EPDM rubber is flexible and comes in large sheets, so it suits larger areas with few joints. GRP fibreglass cures to a rigid, seamless surface that suits smaller roofs and areas that will be walked on. The right choice depends on the roof, so ask the roofer why they recommend one over the other and what guarantee comes with it.
