EPDM Roofing Swindon

EPDM roofing is one of the most durable and cost-effective flat roofing systems available for residential and commercial properties across Swindon and Wiltshire. Made from synthetic rubber, EPDM membranes are highly resistant to UV exposure, temperature extremes, and the wet conditions that Wiltshire’s climate regularly delivers — making them an excellent long-term choice for garage roofs, extensions, and outbuildings.

At Flat Roof Swindon, we install EPDM rubber roofing systems to manufacturer specifications, with a typical lifespan of 25–50 years and minimal ongoing maintenance requirements.

Why EPDM Roofing Is Popular in Swindon

Swindon homeowners increasingly choose EPDM over traditional felt when replacing ageing garage and extension roofs. The reasons are straightforward — felt roofs on properties built across estates in Westlea, Haydon Wick, and Stratton St Margaret typically lasted 10–15 years before needing attention. An EPDM replacement on the same roof will last two to three times longer, requires no recoating, and is far less vulnerable to the freeze-thaw cycles that crack and split felt membranes during Wiltshire winters.

Our EPDM Roofing Installation Process

  1. Survey and preparation — We inspect the existing roof deck for rot, inadequate falls, and drainage issues. Any deck repairs are identified and quoted before work begins.
  2. Deck preparation — The existing membrane is stripped, the deck is cleaned and levelled, and insulation boards are fitted where required to improve thermal performance.
  3. EPDM installation — A single-ply EPDM membrane is rolled out, bonded to the deck using contact adhesive, and fully sealed at all edges, upstands, and penetrations. Seams are kept to a minimum — on most garage and extension roofs, a single sheet covers the entire surface.
  4. Trim and finish — Aluminium trim is fitted around all perimeter edges and drip edges are checked for correct falls to guttering. The finished roof is inspected before sign-off.

EPDM Roofing Costs in Swindon

EPDM roofing typically costs £60–£90 per m² installed, including materials, labour, and standard deck preparation. As a guide:

  • Garage roof (15–20 m²): £900–£1,800
  • Small extension roof (20–30 m²): £1,200–£2,700
  • Larger extension roof (30–50 m²): £1,800–£4,500

All prices are subject to survey. Deck repairs, if required, are quoted separately and discussed before any additional work proceeds.

Frequently Asked Questions

How long does EPDM roofing last?

A correctly installed EPDM roof will typically last 25–50 years. The membrane is highly resistant to UV degradation, ozone, and temperature cycling — the main failure mechanisms for traditional felt. Many EPDM installations come with manufacturer warranties of 20 years or more.

Is EPDM roofing better than felt?

For most residential applications in Swindon, yes. EPDM outlasts felt by a significant margin, requires no periodic recoating, and is less prone to blistering and cracking. The upfront cost is higher than felt, but the total cost of ownership over 25 years is considerably lower when you factor in the reduced need for repairs and replacement.

Can EPDM be installed over an existing felt roof?

In some cases, yes — if the existing deck is sound and the felt is not blistered or waterlogged. We assess this at survey stage. In most cases we recommend a full strip-off to inspect the deck properly, particularly on roofs over 15 years old.

Does EPDM roofing require maintenance?

EPDM requires very little maintenance compared to felt. We recommend an annual visual inspection to check trims, flashings, and outlets, and to clear any debris from the roof surface. The membrane itself does not need recoating or retreating.
