Why choose EPDM rubber roofing in Carterton?

Rubber is a sensible pick in Carterton where a roof sits close to bedrooms or a kitchen and you would rather avoid hot works. It suits porches, bays and dormers too, where the small area means a single sheet can cover the whole roof with no joins at all.

In a town like Carterton, flat roofs are commonly found on bungalows with flat-roofed side extensions and dormers or terraced streets with flat-roofed rear kitchens and bathrooms. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.

How much does an EPDM rubber roof cost in Carterton?

For Carterton we use South East rates: £1,750–£3,100 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.

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?

  • Deck check and replacement of soft or rotten boards
  • EPDM membrane fully bonded, in one sheet where the roof size allows
  • Written workmanship guarantee, plus manufacturer guarantee registration where available
  • New drip and kerb trims, outlets and upstand details

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

EPDM rubber roofing in Carterton: questions

Do you cover Carterton?

Who checks building regulations for a flat roof in Carterton?

Where the work needs approval it goes to West Oxfordshire District Council building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

How much does an EPDM rubber roof cost in Carterton?

£1,750–£3,100 for a typical 18 m² garage roof in EPDM, at South East guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Can a punctured EPDM roof be repaired?

Usually, yes. The area is cleaned and primed, then an EPDM patch or cover tape is bonded over the damage. If water has reached the deck, a survey first is sensible.

Can an EPDM roof be fitted in winter?

Yes, as long as the deck is dry. The adhesives are affected by cold and damp, so very cold or wet days can delay bonding, and the roof is kept temporarily weathertight between dry spells.
