EPDM Rubber Roofing › Cwmbran
Cwmbran's 1950s to 1970s housing came with a lot of flat roofs: integral and attached garages, porch canopies, rear kitchen extensions and flat-topped dormers. Many were finished in felt, and felt that has cracked or opened at the joints is a common reason people ring us. Often the answer is simply a better covering.
EPDM is a single-ply synthetic rubber membrane, laid in one sheet where the size allows and bonded to a sound deck with adhesive. With fewer joints than felt, the weak points are limited to the edges and details, which we do slowly and by hand. That gives you a flat roof that looks tidy and sheds water.

Flat Roofs on Cwmbran Houses
The garages attached to the semis around Llanyrafon, Henllys and Thornhill often have flat roofs that are now decades old. Water sits in the dips, the felt blisters and splits, and the deck underneath starts to soften, so the first job is always checking the boards. Rubber on a soft deck only hides the trouble for a while.
Small porches and flat-roofed extensions in Pontnewydd and Croesyceiliog suit a single sheet of EPDM well, because there are few seams to fail. Upstands at the wall and a neat trim at the drip edge are what keep rain out, and we spend time on those. Neat detailing here is what separates a good roof from a leaky one.
Rain comes off the hills above Upper Cwmbran harder than you might expect, and a flat roof with poor falls will hold it. Where the drainage is poor we tell you, and where insulation is missing we say so, because those are decided before the membrane goes down. There is no point laying rubber on a roof that cannot drain. Honest advice first.
EPDM Jobs We Do in Cwmbran
- EPDM garage roofs — A single-sheet rubber membrane on a garage roof, bonded to a sound deck with trims and upstands formed properly at every edge.
- Extension and porch roofs — Rubber roofing for small flat-topped extensions and porches, where one sheet keeps joints to a minimum and the edges stay neat.
- Dormer flat roofs — EPDM over a dormer cheek and top, with upstands and flashings detailed around the awkward corners that tend to fail first.
- Replacing failed felt — Stripping cracked or blistered felt, checking and repairing the deck, then laying new rubber so the roof is sound again.
- Deck, fall and insulation work — Renewing soft boards, correcting falls so water drains away, and adding insulation where the roof allows it before the membrane is laid.
- Patch repairs on sound EPDM — Locating and curing a puncture or failed detail on a membrane that is otherwise in good order, without renewing the whole roof.
How We Approach an EPDM Roof Here
We look at the existing covering, press the deck from above to find soft areas, check how water leaves the roof and measure up for a single sheet. If the roof is larger than a sheet allows, we explain where a joint will go and how it is made. Everything is explained before the job starts.
We tell you what we have found before we agree the work, including the state of the boards, the falls and the insulation. For larger commercial-scale or complex roofs, our Flat Roofing South Wales section covers the wider range of flat roof work we do. Larger or more complex roofs can be quoted separately.
EPDM Rubber Roofing Guides for Cwmbran
EPDM Rubber Roofing in Cwmbran — Common Questions
Is EPDM suitable for my Cwmbran garage roof?
For most garages, yes. The deck has to be sound and water has to drain away properly. We check the boards and falls first, and tell you if repair is needed before rubber goes on. Most garage roofs in the area are a sensible size for a single sheet.
How is EPDM different from felt?
EPDM is a rubber sheet, usually laid in one piece, so it has far fewer joints than felt. Felt relies on lapped layers and sealed seams, which are where many old flat roofs begin to leak.
Can you lay EPDM over my old felt?
Sometimes, but it depends on the condition of what is underneath. Wet or blistered felt and soft boards usually need stripping and renewing first, otherwise the problems come up through the new membrane.
Can a leaking EPDM roof be repaired?
If the membrane is sound apart from a puncture or a failed detail, yes. We find the source, clean the area and patch or cure it. A membrane that is generally worn out is better replaced.
Do you do bigger flat roofs as well as garages?
We cover small to medium flat roofs in EPDM, such as garages, extensions and dormers. For other types of flat roofing please see our Flat Roofing South Wales section. We will talk through the options with you.
