EPDM rubber roofing in Gainsborough

Garage leaking, or an extension roof that has blistered and split? For property owners in Gainsborough, EPDM rubber is a practical replacement. It is laid cold, copes with temperature swings and leaves few or no joins on a small roof. A free survey tells you whether the deck can be kept or needs replacing.

Why choose EPDM rubber roofing in Gainsborough?

For landlords with property in Gainsborough, EPDM's low upkeep is the main draw: once the outlets are kept clear and the trims are checked once or twice a year, there is little else to do. It also goes down quickly on a small roof, which keeps disruption for tenants to a minimum.

In and around Gainsborough, flat roofs are typically found on shops with flat-roofed rear stores below flats, and on lock-up garage blocks on estates. The East Midlands is drier than the west of Britain, so most flat roofs here fail through age, UV and poor detailing at upstands rather than sheer rainfall.

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?

  • Written workmanship guarantee, plus manufacturer guarantee registration where available
  • EPDM membrane fully bonded, in one sheet where the roof size allows
  • Warm-roof insulation and vapour control layer where required
  • 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.

Who checks building regulations for a flat roof in Gainsborough?

Where the work needs approval it goes to West Lindsey 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 Gainsborough?

£1,550–£2,750 for a typical 18 m² garage roof in EPDM, at East Midlands 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.

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.
