What is EPDM rubber roofing?

EPDM is a synthetic rubber membrane made for flat roofs. On most domestic roofs it is laid as one single sheet, so there are no joins for water to get through. It stays flexible in frost and summer heat, it does not crack or blister like old felt, and because it is bonded with adhesive rather than a torch, there is no fire risk to your house during the work. A well-laid EPDM roof can last 30 to 40 years or more.

How we lay an EPDM roof

We strip the old covering and check the deck. Any soft or rotten boards are replaced with new OSB3, and firrings are added where water has been sitting. The rubber membrane is then fully bonded to the deck, turned up the walls and finished with matching edge trims, a drip into the gutter and lead or EPDM flashings at the house wall.

EPDM, felt or GRP?

EPDM is our first choice for most homes: it is long lasting, quick to lay and has no seams. Torch-on felt costs less but has a shorter life. GRP fibreglass gives a hard, walkable finish for balconies. Our flat roofing page covers all three, and our flat roof replacement cost guide compares prices.

How long does an EPDM rubber roof last?

A properly laid EPDM roof can last 30 to 40 years or more. Most early failures come from poor upstands and edge details, not the rubber itself, which is why we spend our time on those.

Is EPDM better than felt?

For most domestic flat roofs, yes. EPDM is one seamless sheet, it stays flexible in cold weather and it lasts much longer than felt. Felt is cheaper to lay, so it can suit a tight budget.

Can EPDM go over my existing flat roof?

Sometimes, if the old roof is flat, dry and the deck is sound. In most cases we strip back to the deck so we can see what we are building on, because laying new rubber over a wet or rotten deck traps the problem.

Can you lay EPDM in winter?

EPDM adhesives need dry conditions and a minimum temperature, so we plan winter jobs around the forecast. Many winter days are still fine for rubber roofing.

How much does an EPDM roof cost?

Price depends on size, access and the condition of the deck. See our flat roof replacement cost guide for typical figures, or ask us for a fixed written quote.
