How much does an EPDM rubber roof cost in County Durham?

Guide prices including VAT at North East rates. The fixed price comes after a free survey for new and replacement roofs.

Which flat roofs are common in County Durham?

Flat roofs in County Durham sit on low-rise post-war blocks of flats, shops with flat-roofed rear stores below flats and lock-up garage blocks on estates. England averages roughly 870 mm of rain a year; the North East is drier than the west but cold and windy near the coast, so wind uplift and freeze-thaw are in the specification. Approximate 1991–2020 regional averages based on Met Office data.

Building regulations in England

Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. Renovated roofs over heated rooms are insulated to around 0.16 W/m²K where that's feasible, and new extension roofs are built to 0.15 W/m²K. In County Durham the application goes to Darlington Borough Council, Hartlepool Borough Council, Stockton-on-Tees Borough Council and 1 other council. More on the rules.

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.

Do I need building regulations approval to replace a roof with EPDM?

Often, yes. In England, Wales and Northern Ireland, re-covering more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof should be insulated towards the renovation standard where that is feasible; in Scotland, the council's building standards service decides whether a building warrant is needed.

An unheated detached garage normally falls outside these rules, and a patch repair is treated differently from a full re-cover.

In practice that means a warm roof: insulation above the deck, a vapour control layer beneath it and the EPDM on top. The extra thickness lifts the finished roof, so at survey we check door thresholds, window cills, wall flashings and upstand heights, aiming for an upstand of about 150 mm above the finished surface. Where approval is needed, we deal with building control or building standards for you. The building regulations page and our warm vs cold roof guide go into more detail.
