EPDM and fibreglass flat roofs in Peterborough

Flat Roofing & EPDM FAQs

Can you overlay the existing felt?

Only if the deck below is dry and sound, and we'll lift a section to check. Overlaying a soft deck buys a year or two and costs the whole job again.

How long should a new flat roof last?

A well-installed EPDM or GRP roof on a sound, correctly falling deck should give decades of service. What kills flat roofs early is ponding water, poor upstands and being laid over a wet deck — all avoidable.

Do you insulate at the same time?

We can build a warm deck with insulation above the structure, which usually makes sense if the roof is coming off anyway and the room below is cold or prone to condensation.

EPDM, fibreglass or felt — which should we choose?

It depends on the deck, the traffic it takes and the budget. EPDM suits most extensions and garages, GRP suits balconies and anything walked on, and felt still makes sense on larger or awkward outbuildings. We'll set out the options at inspection.

Do we need permission from Peterborough City Council?

Most like-for-like roof work doesn't need consent, but listed buildings and conservation areas can. If your property looks like it falls into that, we'll say so at inspection so it's dealt with before work starts.
