Why choose EPDM rubber roofing in Penarth?

Rubber is a sensible pick in Penarth where a roof sits close to bedrooms or a kitchen and you would rather avoid hot works. It suits porches, bays and dormers too, where the small area means a single sheet can cover the whole roof with no joins at all.

Penarth's flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms, with plenty on low-rise post-war blocks of flats too. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.

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?

  • Deck check and replacement of soft or rotten boards
  • Warm-roof insulation and vapour control layer where required
  • EPDM membrane fully bonded, in one sheet where the roof size allows
  • Strip-out of the old covering, with waste taken away

Building regulations in Wales

The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

How much does an EPDM rubber roof cost in Penarth?

£1,450–£2,600 for a typical 18 m² garage roof in EPDM, at Wales 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 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.
