Why choose EPDM rubber roofing in Preston?

EPDM makes sense for a property in Preston 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.

Preston's flat roofs are mostly on shops with flat-roofed rear stores below flats, with plenty on bungalows with flat-roofed side extensions and dormers too. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.

How much does an EPDM rubber roof cost in Preston?

At North West guide rates, a typical 18 m² garage roof in EPDM comes to £1,500–£2,650 including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.

What's included?

  • Warm-roof insulation and vapour control layer where required
  • EPDM membrane fully bonded, in one sheet where the roof size allows
  • New drip and kerb trims, outlets and upstand details
  • Written workmanship guarantee, plus manufacturer guarantee registration where available

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.

Who checks building regulations for a flat roof in Preston?

Where the work needs approval it goes to Preston City 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 Preston?

£1,500–£2,650 for a typical 18 m² garage roof in EPDM, at North West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Can EPDM be laid over an old felt roof?

Sometimes, but we usually recommend stripping old felt first. Overlaying hides any rot or wet insulation underneath, and over a heated room a full replacement is often when insulation has to be added anyway.

How long does it take to fit an EPDM roof?

A single garage typically takes one to two days and an insulated extension roof two to three, weather permitting. Larger roofs, scaffold and complex details add time.
