EPDM Rubber Roofing › Caerphilly › Guide
EPDM is a tough membrane, but it is not immune to punctures, lifting edges or failed details. Many Caerphilly flat roofs on garages and extensions can be repaired without being replaced. Whether a repair is worth doing depends on the condition of the membrane and, just as importantly, what lies underneath it.
When a repair makes sense
If the main sheet is sound, flexible and well bonded, a local fault can usually be repaired. Typical cases include a puncture from a fallen branch, a lifted seam, a failed corner or a poorly sealed pipe or rooflight upstand. Local weather makes this more of a concern than people expect.
Such repairs are common on garage roofs and rear extensions under trees, where debris and branches fall. We aim to fix the actual fault and not just cover the symptom. We would rather tell you straight than sell you something unnecessary.
How we repair it
The area is cleaned and dried, and a patch of compatible material is bonded over the damage with the proper adhesive or cure. Edges are rolled down firmly and checked so water cannot track underneath. It does not take long to check, and it saves guesswork.
Where the problem is at an edge trim or upstand, we may refix or renew that detail. Repairs need dry conditions, so on a wet valley town like Caerphilly we wait for a suitable window. We look at this on site rather than guessing from the road.
- Clean and dry the damaged area
- Bond a compatible patch or apply a cure
- Refix or renew lifting edge trims
- Check upstands, corners and penetrations
- Test that water drains away from the repair
When the membrane needs replacing
If the membrane is brittle, widely lifted, damaged in many places or the adhesive has failed over large areas, patching only delays the problem. In those cases a new membrane is a more honest recommendation. Every roof in the area behaves a little differently.
We also look underneath. If the deck is soft or water has been getting in for a long time, boards may need replacing first. We tell you plainly when a repair is not the sensible route. We explain what we find in plain terms before any work starts.
Finding the real cause
A leak that shows on a ceiling is not always above it. Water can run along the deck before dripping, so the visible stain can be some distance from the real fault. We trace it properly before repairing anything. It is worth getting it looked at before the next wet spell.
Poor falls and blocked outlets cause ponding that stresses details. We check drainage as well as the membrane, because a perfect patch on a roof that ponds may just fail again. That is the sort of detail we check on every visit.
What you can do safely
From inside, look at ceilings for stains and note whether they appear after rain. From the ground, check gutters and outlets for overflow. That is all you need to gather for us. Local weather makes this more of a concern than people expect.
Please do not climb onto the roof or cut at the membrane yourself. Call us for a proper look and we will say whether a repair is enough. Our Flat Roofing South Wales section covers other flat roof work if needed. We would rather tell you straight than sell you something unnecessary.

Common Questions
Can a small hole in EPDM be patched?
Yes, if the surrounding membrane is sound. The area is cleaned, dried and a compatible patch bonded over the damage. We also check why it happened, such as overhanging branches, so it does not recur. It does not take long to check, and it saves guesswork.
Does a repair mean the roof is failing?
Not necessarily. A single puncture or lifted corner on an otherwise good roof is a straightforward repair. Widespread damage or a soft deck suggests a bigger problem, and we say so honestly. We look at this on site rather than guessing from the road.
Can you repair it in the rain?
Not properly. Adhesive and cures need a dry surface, so we wait for suitable weather. If water is coming in, we can advise on temporary steps you can take from inside. Every roof in the area behaves a little differently.
