Question answered
How much should an EPDM roof cost?
The short answer
Published UK guides put EPDM at about £90 to £130 per m² (MyBuilder, updated 21 August 2026). Treat that as a national middle ground and not a price for your own roof. Small roofs, awkward access, a damaged deck, added insulation and the number of edges and outlets all move the figure. Your own price is fixed after a survey of your roof, as one written total.
EPDM, the single-sheet rubber membrane used on flat roofs, has a published typical price per square metre. What it costs on your roof depends on a handful of things that a survey can pin down.
What the published guides say per square metre
The MyBuilder flat roof guide (updated 21 August 2026) gives EPDM a typical UK range of £90 to £130 per m². In the same guide, felt sits at £70 to £100 and GRP (resin and glass matting, sold as fibreglass) at £95 to £150. For a whole flat roof it quotes £2,800 to £7,500 overall, with an all-materials average of £75 per m².
Two other figures help. MyBuilder's garage roof guide puts EPDM at £70 to £100 per m², which fits the idea that a simple roof with few details costs less per metre. Checkatrade, citing a repair rather than a new roof, shows EPDM at £120 to £170 per m² and says its costs exclude VAT.
Treat all of these as the middle of a national market, not as what any contractor on the Sussex coast will charge. They tell you whether a quote is in the right area, nothing more.
What pushes an EPDM price up or down
Size comes first. A small roof still needs the same edge trims, corner details and outlets as a large one, so the price per metre tends to rise as the area falls. A long, plain rectangle is the simplest shape to cover; a roof with a rooflight, a chimney, two upstands and a step is not.
Access is next. A ground-floor extension can often be reached from a ladder, while a roof over an upper storey may need scaffolding. MyBuilder's re-roof guide gives a figure of about £1,125 for scaffolding on a whole-house job, which shows the scale.
Then comes what lies under the rubber. If the old covering is stripped and the boards beneath are damp or rotten, they are renewed, and that adds to the total. Insulation laid over the deck, new falls cut with tapered boards, and a new drainage outlet each add to the work too. None of that can be priced honestly from a photograph sent by text, which is why we survey first.
Checking that a quote covers the whole job
Ask whether the price includes VAT. The standard rate is 20%, and some published guides, Checkatrade's among them, state their figures without it. A quote that excludes VAT can look a fifth lower than one that includes it, and the two are not alike.
Ask about scaffolding as well. Where the roof cannot be reached safely without it, it should be inside the total or named as an extra.
Ask where the old covering and the rubbish end up, and what the plan is when the boards underneath prove unsound after stripping. A good answer is a clear one, such as the boards being replaced at an agreed point once you have seen photographs.
Any guarantee should be in writing too, saying what it covers and whether an insurer stands behind it. After the survey our quote is sent as a single written figure, and we want that figure to look fair beside the work described.
Price against the life of the roof
EPDM costs more to lay than felt and is expected to last longer. GreenSpec lists an expected service life of 20 to 30 years, while the Less guide (March 2026) gives 30 to 50. Read that as 20 to 30 years or more, depending on exposure, workmanship and upkeep. Less puts torch-on felt at 10 to 20 years.
So a higher price per metre can still be the lower cost over the years, provided the roof is laid well and looked after. Our page comparing flat roof coverings over their whole life works through that idea, felt included. Keep in mind that every figure here is a typical range, and a lifespan is never a promise.
EPDM has weak points as well. Punctures from a dropped tool or a heavy foot, and the glued details at upstands, are where it usually gives trouble; the drawbacks of EPDM are set out plainly there.
How a rubber roof gets priced here
We survey the roof first and photograph the covering, edges, outlets and any soft boards. The survey is also where we decide whether a repair would do. A patch at one upstand that properly cures the leak is the job we would recommend, not a full new roof.
When replacement is the right answer, the written quote names what is being laid, what happens with the deck and insulation, and how the old material is cleared. Questions about any of that are welcome, and we will answer them with photographs of your own roof rather than general reassurance. A roof near the sea also deserves attention to how edges and trims are fixed against gusts.
A new flat roof also leaves a paper trail that matters later. Photographs and invoices help when an insurer asks about the state of the roof, as we explain in why insurers ask about flat roofs. The wider choices are covered on our flat roofing page.
EPDM pricing: two more questions
Is a rubber roof on a garage priced like one on a house extension?
Not quite. MyBuilder's garage guide gives EPDM at £70 to £100 per m², and a single flat garage at £700 to £1,000. A garage is usually a plain shape with few details. An extension roof often has walls on two or three sides, a rooflight or a larger area to drain, and each adds to the work.
Do the published EPDM prices include scaffolding and VAT?
Not always. Checkatrade states its repair costs exclude VAT, and a guide's per-metre figure for the covering says nothing about access equipment. Get the roofer to state on paper whether the total on offer covers both, because the answer can shift the figure by a good deal.
