EPDM and fibreglass flat roofs in Mildenhall

Flat Roofing & EPDM FAQs

Is the roof walkable?

GRP takes foot traffic and suits balconies and terraces. EPDM is fine for maintenance access but isn't intended as a walking surface — if you need a usable deck, say so and we'll specify accordingly.

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.

Why does water sit on our flat roof after rain?

Insufficient fall, a sagging deck or a blocked outlet. On Mildenhall extensions it's usually falls that were never set properly. We reset falls with firrings rather than lay new membrane over the same puddle.

Does the exposure here change what you'd specify?

Yes. Open fen exposure means wind uplift is the main enemy, so clipping patterns, verge fixing and adequate falls on flat roofs get more attention than they might in a sheltered street.

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.
