Why choose EPDM rubber roofing in Gosport?

Where an older flat roof in Gosport has a sound structure but a tired covering, EPDM is a straightforward upgrade: strip, check the deck, add a warm-roof build-up if the room below is heated, and bond the new membrane. It also makes a good base for a sedum green roof.

In and around Gosport, flat roofs are typically found on terraced streets with flat-roofed rear kitchens and bathrooms, 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 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
  • Strip-out of the old covering, with waste taken away
  • New drip and kerb trims, outlets and upstand details
  • EPDM membrane fully bonded, in one sheet where the roof size allows

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.

£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.

Does an EPDM roof need maintenance?

Very little. Clear leaves from outlets and gutters, look over trims and upstands once or twice a year and after storms, and keep foot traffic to a minimum.

Can you put a green roof on top of EPDM?

Yes. EPDM is often used under sedum, with a protection layer, drainage and growing medium laid on top. The structure must be able to carry the extra weight, which we check before quoting.
