Choices to weigh up in Bournville

GRP fibreglass roof

Glass-reinforced plastic laid as a liquid resin and matting over a board deck, which cures into a hard, joint-free, walkable surface. GRP works well on roofs with awkward shapes, roof lights and balconies, and comes in grey and other colours. It must be laid in dry conditions and needs a stable deck.

EPDM rubber roof

A single sheet of synthetic rubber bonded to the deck, often in one piece with no joints on smaller roofs. EPDM handles temperature changes well, is quick to lay and needs little maintenance. It's a good all-round choice for garages and extensions, though it has a plain black finish and needs care around complex details.

Flat roofing in Bournville: common questions

Which lasts longer, EPDM or GRP?

Both last far longer than old felt when properly laid, and the quality of the installation matters more than the material. EPDM is flexible and handles movement well, while GRP gives a hard, walkable, joint-free finish that suits complex shapes. Manufacturers' expected lifespans vary by product, and the guarantee terms for your roof are set out in your quote.
