Why choose EPDM rubber roofing in Hatfield?
Rubber is a sensible pick in Hatfield 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.
Around Hatfield, flat roofs are common on low-rise post-war blocks of flats and on terraced streets with flat-roofed rear kitchens and bathrooms. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.
How much does an EPDM rubber roof cost in Hatfield?
Guide price in Hatfield: £1,700–£2,950 for a typical 18 m² garage roof in EPDM, including VAT at East of England rates. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), EPDM rubber | £1,700–£2,950 |
| Extension (20 m²), EPDM, new deck + insulation | £2,950–£5,150 |
| Porch or bay (4 m²), EPDM | £800–£1,300 |
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?
- EPDM membrane fully bonded, in one sheet where the roof size allows
- Written workmanship guarantee, plus manufacturer guarantee registration where available
- Warm-roof insulation and vapour control layer where required
- 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.

How much does an EPDM rubber roof cost in Hatfield?
£1,700–£2,950 for a typical 18 m² garage roof in EPDM, at East of England 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.
