Why choose EPDM rubber roofing in Northampton?
Where an older flat roof in Northampton has a sound structure but a tired covering, EPDM is a straightforward upgrade: strip, check the deck, add a warm-roof build-up if the room below is heated, and bond the new membrane. It also makes a good base for a sedum green roof.
Around Northampton, flat roofs are common on terraced streets with flat-roofed rear kitchens and bathrooms and on 1930s semis with flat-roofed garages and kitchen extensions. 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.
How much does an EPDM rubber roof cost in Northampton?
For Northampton we use East Midlands rates: £1,550–£2,750 is the guide for a typical 18 m² garage roof in EPDM, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), EPDM rubber | £1,550–£2,750 |
| Extension (20 m²), EPDM, new deck + insulation | £2,750–£4,800 |
| Porch or bay (4 m²), EPDM | £750–£1,250 |
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.
What's included?
- Strip-out of the old covering, with waste taken away
- EPDM membrane fully bonded, in one sheet where the roof size allows
- New drip and kerb trims, outlets and upstand details
- Deck check and replacement of soft or rotten boards
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.
