Why choose EPDM rubber roofing in Colwyn Bay?
Choose EPDM in Colwyn Bay if you want a long service life without paying for a hard, walkable finish you do not need. With good detailing it typically lasts 25 years or more, and manufacturer material guarantees are available on many EPDM systems, registered for you where the system allows.
Colwyn Bay's flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms, with plenty on 1960s and 1970s link-detached houses with flat-roofed garages and porches too. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.
How much does an EPDM rubber roof cost in Colwyn Bay?
For Colwyn Bay we use Wales rates: £1,450–£2,600 is the guide for a typical 18 m² garage roof in EPDM, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), EPDM rubber | £1,450–£2,600 |
| Extension (20 m²), EPDM, new deck + insulation | £2,600–£4,500 |
| Porch or bay (4 m²), EPDM | £700–£1,150 |
How long does an EPDM roof last, and what guarantees come with it?
A well-specified EPDM roof typically lasts 25 to 50 years, and one BBA assessment of an EPDM membrane puts its expected life at 35 years or more. Problems usually come from poorly bonded upstands, damaged trims or ponding, rather than the rubber itself.
Three separate documents can sit behind an EPDM roof:
- Manufacturer material guarantee: covers the membrane and, on some systems, the wider build-up. Many need registration and a specified build-up, so we register it for you where the system allows.
- Our written workmanship guarantee: given on every re-roof, with the length set out in your quote.
- Insurance-backed guarantee: an option worth asking about if you want cover that does not depend on the contractor still trading.
A BBA certificate is an assessment of the product, not a guarantee. Our guide to flat roof guarantees explains the differences, and the lifespan guide compares EPDM with the other systems.
What's included?
- Written workmanship guarantee, plus manufacturer guarantee registration where available
- Deck check and replacement of soft or rotten boards
- Strip-out of the old covering, with waste taken away
- EPDM membrane fully bonded, in one sheet where the roof size allows
Building regulations in Wales
The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.
