What is the best material for a flat roof?
Felt, GRP fibreglass and EPDM rubber compared — and how to choose for your building.
Built-up felt
Modern torch-on felt systems are widely used and can be repaired in patches.
GRP fibreglass
A seamless, hard-wearing finish well suited to smaller roofs, balconies and areas with foot traffic.
EPDM rubber
A single-sheet membrane that suits simpler roof shapes with few penetrations.
Choosing
Roof size, access, foot traffic, plant equipment and budget all play a part. We'll recommend the system that suits your roof.
