EPDM Rubber Roofing Specialists in Caerphilly
Rubber roofing has quietly become the best answer to the valleys’ oldest problem: flat roofs that fail. Across Caerphilly - from garages in Bedwas and Machen to extensions in Trethomas and Nelson - our rubber roofing Caerphilly team replaces tired felt with a single EPDM membrane that has no seams for water to find.
South Wales rain is exactly what EPDM was made for. Where felt blisters, cracks and peels after a decade of freeze-thaw, rubber stays flexible from minus forty to plus one hundred degrees, resists ponding water, and simply does not rot. It is why we fit more EPDM rubber roofs in Caerphilly every year.
Whether you need a new rubber roof installation, an EPDM repair, or a felt-to-rubber upgrade on a garage or extension, we measure, quote and fit with the same care as the roofer Caerphilly homeowners trust for every other roof in town.

Signs a Flat Roof Is Ready for Rubber
If your existing flat roof shows any of these, an EPDM upgrade is usually the smart money.
Recurring Leaks
Felt patched more than once will leak again - rubber ends the cycle.
Ponding Water
Standing water destroys felt in years; EPDM is unaffected by it.
Blistered or Bubbling Felt
Trapped moisture lifting the surface means the covering is finished.
Cracked & Crazed Surface
Sun and frost leave old felt brittle and full of hairline cracks.
Lifting Edges & Trims
Wind gets under failed edges and peels the whole covering back.
Felt Over 15 Years Old
At that age felt owes you nothing - replace it once, in rubber.

Frequently Asked Questions
Straight answers about EPDM rubber roofing in Caerphilly.
How long does a rubber roof last?
Properly installed EPDM has a life expectancy of 40-50 years – roughly three times longer than traditional felt – and it barely needs maintenance along the way.
Is rubber roofing better than felt?
For almost every flat roof, yes: EPDM is seamless, flexible in frost, unaffected by ponding water and does not blister or crack like felt. It costs a little more up front and repays it many times over.
What is the difference between EPDM and GRP fibreglass?
Both are excellent modern systems. EPDM is a flexible one-piece membrane, ideal for larger simple roofs; GRP is a rigid seamless laminate, great for complex shapes and walkways. We fit both and will recommend the right one for your roof.
Can you fit rubber over my existing roof?
EPDM needs a clean, dry, solid deck – sometimes the old covering can stay, but usually stripping back gives a far better, longer-lasting result. We assess honestly before quoting.
How much does a rubber roof cost in Caerphilly?
A typical garage costs less than most people expect, and extensions scale with size and insulation choice. Every quote is free, written and itemised.
