Why choose EPDM rubber roofing in Bromley?
Where an older flat roof in Bromley 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.
Bromley's flat roofs are mostly on shops with flat-roofed stores below flats above, with plenty on kitchen extensions and roof terraces behind period houses too. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.
How much does an EPDM rubber roof cost in Bromley?
For Bromley we use London rates: £1,900–£3,350 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 | £1,900–£3,350 |
| Extension (20 m²), EPDM, new deck + insulation | £3,350–£5,850 |
| Porch or bay (4 m²), EPDM | £900–£1,500 |
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?
- Deck check and replacement of soft or rotten boards
- New drip and kerb trims, outlets and upstand details
- Strip-out of the old covering, with waste taken away
- Warm-roof insulation and vapour control layer where required
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 Bromley?
£1,900–£3,350 for a typical 18 m² garage roof in EPDM, at London guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can you walk on an EPDM roof?
Occasionally, for maintenance, yes, but EPDM is not designed as a regular walking surface. Where you need a route to plant or windows, walkway pads can be bonded on, or GRP may be a better fit.
Can a punctured EPDM roof be repaired?
Usually, yes. The area is cleaned and primed, then an EPDM patch or cover tape is bonded over the damage. If water has reached the deck, a survey first is sensible.
