EPDM Rubber Roofing › Pontypridd › Guide
EPDM is a tough rubber membrane, and when something goes wrong on a Pontypridd garage, extension or dormer roof, owners often ask whether it can be mended. Often it can. This guide explains what a repair involves, what limits it and when we would advise covering the roof again. Local conditions are used lightly, as every roof differs.
What usually goes wrong
Most EPDM faults are local rather than widespread. A puncture from a fallen branch or a dropped tool, a lifted edge, a failed seam or a poorly sealed corner can all let water in while the rest of the sheet remains sound. Because the membrane is laid in one piece, water can travel under it, so the leak and the damp patch inside may be some distance apart.
How a repair is done
We clean and dry the area, then bond a patch of matching material over the damage using the right adhesive and cure. Edges and corners are re-formed carefully, and trims or upstands are refixed if they have lifted. Small repairs are practical and can be done in a short visit, as long as the surrounding membrane is in good condition and the weather allows. We keep the explanation plain and tell you what we see on your own roof.
- Damaged area cleaned and dried before patching
- Patches and cures bonded with the right adhesive
- Lifted edges, trims and upstands refixed
- Surrounding membrane checked for further faults
When repair is not enough
If the deck is soft or rotten, a patch on top will not hold. The same is true if water is ponding because the falls are poor, or if the membrane is split widely or bonded poorly across much of the roof. In those cases we say so and explain what a re-cover would involve, including any deck repair, rather than patching for the sake of it. Ask for the reasoning in plain words, and expect a straight answer.
Local conditions
Valley rain, falling leaves from nearby trees and moss in the shade all affect flat roofs in Pontypridd. Outlets that clog hold water on the roof, which stresses seams and edges. Dormer flats and extension roofs against taller walls collect debris at the upstands, so we check these first. Our Flat Roofing South Wales section covers other coverings if your roof is not EPDM. We keep the explanation plain and tell you what we see on your own roof.
What to ask before agreeing to a repair
Ask what caused the damage, whether the deck has been checked and what happens if the patch fails. A fair answer covers the cause as well as the patch. We would rather tell you honestly that a roof has had its day than patch a roof that will fail again.

Common Questions
Can a small tear in EPDM be fixed?
Usually yes. We clean and dry the area, then bond a patch over the tear with the proper adhesive and cure. It works well where the surrounding membrane and the deck are sound, and we check both before starting.
How do I know if my EPDM roof is beyond repair?
Widespread splits, a soft or rotten deck, persistent ponding and poor bonding across large areas point to a re-cover. We look at these and tell you whether repair is worthwhile or whether covering again makes better sense.
Can I patch the roof myself?
We would rather you did not. It means going onto the roof, and the wrong adhesive or a poorly prepared surface will fail. From inside and the ground you can note where damp appears, and then call us for a proper look.
