EPDM Rubber Roofing › Caerphilly
EPDM is a single-ply synthetic rubber membrane. It is bonded to a sound deck, finished with edge trims and upstands, and has far fewer joints than felt, which is why it suits so many small and medium flat roofs. On a rainy valley town like Caerphilly, fewer joints and well-formed details matter, since water finds any weak spot in a flat roof sooner or later.
T & T Roofing South Wales, based in Port Talbot, lays EPDM across the Caerphilly area. Our Flat Roofing South Wales section covers the wider range of flat roof work if you are weighing up options. We lay it carefully and finish edges and corners by hand, so the membrane does what it is meant to for the building underneath.

Flat roofs around Caerphilly
Caerphilly has plenty of flat-roofed additions. Rear kitchen extensions on the terraces, garages beside the post-war semis and porches on the estates all tend to have flat tops that have seen decades of rain coming down off the hills. Older felt on those roofs often cracks and blisters, and by the time a stain shows on a ceiling the boards underneath may already be damp.
Persistent wet weather exposes weak points quickly. Ponding near a drain, a lifting edge or a cracked patch around a rooflight can all let water into the deck, so the condition of the timber below matters as much as the surface. We are careful to find out whether the problem is the surface, the deck or the drainage, because replacing only one of those can leave the leak in place.
Larger roofs in Bedwas or Ystrad Mynach, such as a long garage run or a dormer flat, benefit from a single sheet where we can manage it. Leaf fall from nearby trees can clog outlets, so we look at drainage too. A roof can look fine from the upstairs window yet have soft boards, so we always inspect the deck itself and not just the covering above it.
EPDM work we do in Caerphilly
- Garage roof renewal — The old covering is stripped, the deck checked, and a single EPDM sheet is bonded down with trims and neat corners.
- Extension flat roofs — Rear and side extensions get a membrane laid to suitable falls, with upstands against the house wall.
- Porch and bay roofs — Small roofs have detailed corners and edges, which we form carefully because the fiddly parts are where leaks start.
- Dormer flat roofs — The flat top of a dormer is recovered in EPDM, with the cheeks and upstands finished properly.
- Deck repairs and insulation — Damaged boarding is replaced and insulation added where appropriate before the membrane goes on.
- Patch repairs on sound membrane — Where the membrane is sound, small punctures and failed seams can be patched or cured without recovering.
How we approach EPDM in Caerphilly
We begin by looking at the deck, the falls and where the water goes. A flat roof that ponds will not be fixed by a new surface alone, so we explain what needs adjusting. From inside, damp patches or stained ceilings tell us a lot. Please do not walk on a flat roof you think may be weak. We then explain the order of work in plain language, including how the edges, upstands and any rooflight or pipe details will be handled.
Adhesive is applied to a dry, sound deck on a settled day, which on a hillside town like this means choosing our moment with care. Edges and corners are formed by hand. Work may need Building Regulations checks, and we advise before work starts. Afterwards we check that water drains away freely and leave the roof clean, with the gutters and outlets clear.
EPDM Rubber Roofing Guides for Caerphilly
EPDM Rubber Roofing in Caerphilly — Common Questions
What is EPDM?
It is a synthetic rubber membrane supplied in large sheets and bonded to the roof deck. Because it can be laid in one piece on many roofs, there are fewer joints than with felt, which is where leaks often start. We look at the roof first and advise honestly.
Will EPDM suit my garage roof?
Usually, yes. Garages are one of the most common jobs, provided the deck is sound and the water can drain away. We check the boarding and falls before quoting anything. Each roof is assessed on its own condition.
Can you lay EPDM over my old felt?
It depends on the state of what is underneath. We look at the old covering and deck and tell you honestly whether it can stay or should come off first. We can talk through the choices on site.
What if the deck is rotten?
Damaged boards are cut out and replaced before the membrane is laid. A membrane over a weak deck will not last, so we check this properly and show you what we find. It depends on the deck and the drainage, which we check.
Do you work outside Caerphilly itself?
Yes, including Bedwas, Machen, Llanbradach, Nelson and Ystrad Mynach. Flat roofs on garages and extensions are common in all of them, and we treat each roof individually. Call us and we will take a proper look.
