Flat Roofs & EPDM in Henleaze
Rear extensions, dormers, garages and bay tops re-covered in single-piece EPDM rubber membrane, with the edges, upstands and outlets detailed properly.
The usual culprits
Ponding
A flat roof should never be truly flat. Water standing in dips speeds up wear and finds any weak seam. We correct falls with firrings where needed.
Edges and upstands
Most leaks start where the roof meets a wall or a trim, not in the middle. Upstands need to run up behind the flashing, not stop short.
Blocked outlets
Leaves from street trees and gardens silt up outlets and gutters, and water backs up under the edge.
Tired felt
Older mineral felt cracks and blisters. Patching felt that has reached that stage rarely lasts.
What a single-piece rubber roof gives you
One sheet, no field seams
On most domestic roofs the membrane goes down in a single piece, so there are no joints across the roof to fail.
No naked flames
EPDM is bonded with adhesive, not torched, which matters on a timber dormer or next to a neighbour’s extension.
Moves with the building
Rubber stays flexible through hot summers and freezing nights.
Neat to look at
Trims are dressed cleanly, which counts on a dormer that faces the street.
How we re-cover a flat roof
Inspect the deck
Old covering lifted and the boards checked. Soft or rotten decking is replaced and shown to you first.
Set the falls
Firrings added where water has been ponding.
Membrane and trims
EPDM bonded down, with upstands, drip trims and outlets formed around it.
Flashings
Lead or EPDM flashing tucked into the wall above the upstand.
Flat roof FAQs
Can you go over the old felt?
Sometimes, if the deck is sound and dry. Often it is not, and covering it hides the problem. We check before we quote.
Can a flat roof take a roof terrace?
Not without the right structure, membrane and permission. Ask us to look at it.
Do you insulate flat roofs?
Yes, where it is required or wanted. Building regulations can apply when a roof is renewed.
Flat roof leaking or worn out?
Send us a photo and we will tell you whether it needs a repair or a new covering.
