EPDM rubber roofing in Sandown

In Sandown and across Isle of Wight, our teams fit EPDM rubber roofing to homes and small commercial buildings. The old covering is stripped, the deck is checked and repaired, insulation is added where the regulations call for it, and a new rubber membrane is bonded down with properly formed upstands and trims.

Why choose EPDM rubber roofing in Sandown?

EPDM makes sense for a property in Sandown when the roof is a straightforward shape, such as a garage or rear extension, and nobody needs to walk on it. A single sheet leaves few joins to fail, and because it is cold-applied there is no naked flame near timber fascias or a lived-in home.

In and around Sandown, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, and on newer estates where the first extension roofs are now being replaced. 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 Sandown?

For Sandown 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?

  • Warm-roof insulation and vapour control layer where required
  • New drip and kerb trims, outlets and upstand details
  • Written workmanship guarantee, plus manufacturer guarantee registration where available
  • Deck check and replacement of soft or rotten boards

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.

How much does an EPDM rubber roof cost in Sandown?

£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 you walk on an EPDM roof?

Occasionally, for maintenance, yes, but EPDM is not designed as a regular walking surface. Where you need a route to plant or windows, walkway pads can be bonded on, or GRP may be a better fit.

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.
