FAQs

Flat roof questions.

How long does a flat roof last?

A properly fitted GRP or EPDM roof should last 20 to 30 years, far longer than old felt.

Can you fit it in winter?

Rubber can go on in most weather. GRP needs dry conditions, so we plan around the forecast.

Do I need planning permission?

Not for replacing an existing flat roof like-for-like. Adding a lantern usually doesn’t either.

Can you add insulation?

Yes. We can make it a warm roof, which keeps the room below warmer and meets building regs.
