The material

EPDM is a single sheet of synthetic rubber, laid in one piece over a flat roof, with no seams to lift or joints to split.

The single biggest cause of flat roof leaks is failed seams, and EPDM has almost none, so there is little to go wrong. On a York garage or extension it lasts 25 to 40 years and carries our 20-year written guarantee on top of the membrane warranty.

Rubber flexes with heat and cold instead of going brittle and splitting the way old felt does. It wants a flat or low pitch and only light foot traffic, which is why it belongs on garages, single-storey extensions, dormers and porches rather than a roof you will walk on daily.

A new flat roof deck boarded out and framed on a York extension, ready for the membrane

A flat roof is only as good as the deck beneath it.

EPDM is only as good as the boards under it. A soft deck is re-boarded first, then swept clean and dry so the single sheet bonds for good. Most of ours goes on garage and extension roofs across York, Tadcaster and Wetherby, part of our flat roof services.

The honest version

Is EPDM right for your roof?

For it

Best for flat and low-pitch roofs: garages, single-storey extensions, dormers, porches and bay tops. Anywhere a tiled roof will not sit and the roof is barely walked on. One sheet with almost no joints, 25 to 40 years of life at a price that competes with felt.

Against it

Not the pick for steep or busy roofs. Steep pitches want tile or slate, and balconies, terraces or any surface in daily use suit GRP fibreglass better. It is also only as good as the deck: a soft deck has to be re-boarded first, which adds to the price.

No hiding it

What an EPDM flat roof costs.

It competes with felt on price and lasts twice as long. In York, indicative bands run:

Small roof, up to 15 m²£600 to £1,000

Medium, 15 to 30 m²£900 to £1,800

Large, 30 m² and up£1,600 to £3,200

Deck condition, penetrations, edge detailing and access move the figure. A free survey turns the band into a fixed written quote within 24 hours.

Repairs and honesty

When a patch beats a recover

Where a failure is localised and the rest of the sheet is sound, a patch bonds to the existing EPDM with glue and seam tape. We are honest at the survey about when a repair makes sense and when a full recover is the better spend.

Light foot traffic for maintenance is fine, but EPDM is not meant for regular use as a walkway or balcony. For a flat roof you will walk on often, GRP fibreglass is the better material.

How we fit it

Surveyed, stripped, bonded, proven

Send a photo or ring. WhatsApp a picture of the flat roof and the building age. We can usually say whether EPDM fits before we visit, free.
Free survey. Deck, falls and upstands checked properly. We tell you honestly if EPDM is the right system or if GRP or felt suits better.
Strip and prep the deck. Old covering off, deck re-boarded where it is soft, then swept clean and dry so the sheet bonds for good.
Bonded and dressed. One EPDM sheet bonded down, trims and upstands dressed, and the finished roof photographed before we leave.

Every EPDM roof carries a 20-year manufacturer warranty and our 20-year workmanship guarantee, in writing.

Before you book

EPDM questions

Is EPDM better than felt?

EPDM is a single rubber sheet with no joints, lasts 25 to 40 years against felt's 15 to 25, and needs far less maintenance. Felt is cheaper up front and still sensible for a shed or a tight budget, but on a garage or extension you mean to keep, EPDM is the better value over its life.

How long does an EPDM roof last?

25 to 40 years when the deck is sound and the sheet is bonded and dressed properly. The membrane usually outlives the deck beneath it. We back ours with a 20-year manufacturer warranty and a 20-year written workmanship guarantee.

How much does an EPDM flat roof cost in York?

Small roofs up to 15m² run £600 to £1,000, medium 15 to 30m² £900 to £1,800, and large 30m² and up £1,600 to £3,200. Deck condition, penetrations, edge detailing and access move the figure. We fix it in writing within 24 hours of a free survey.

Can you walk on an EPDM roof?

Light foot traffic for maintenance is fine, but EPDM is not meant for regular use as a walkway or balcony. If you want a flat roof you will walk on often, GRP fibreglass is the better material.

Can an EPDM roof be repaired?

Yes. Where the failure is localised and the rest of the sheet is sound, a patch bonds to the existing EPDM with glue and seam tape. We are honest at the survey about when a repair makes sense and when a full recover is the better spend.
