What Does an EPDM Rubber Roof Cost in Derby?
EPDM rubber roof cost in Derby runs between £70 and £100 per square metre, fully installed. That figure covers materials, labour, and standard edge detailing on a straightforward residential job — deck repairs, insulation upgrades and scaffolding are priced separately, and covered further down this page.
Derby Roofers has been installing EPDM rubber roofing across Derby and Derbyshire for over 20 years. We fit Firestone RubberCover EPDM on every job and carry insurance-backed guarantees on all our flat roof work — on garages in Chaddesden, extensions in Mickleover, and commercial flat roofs across the wider Derbyshire area.
- Small garage roof (15–20 m²): £1,050–£2,000
- Single garage with upstands (18–22 m²): £1,260–£2,200
- House extension roof (25–35 m²): £1,750–£3,500
- Large extension or outbuilding (40–50 m²): £2,800–£5,000
- Commercial flat roof (50 m²+): Call for a free survey
These prices assume the existing deck is in sound condition. On older Derby properties — particularly post-war semis in Spondon, Chaddesden and Allestree — the plywood or OSB deck often needs replacing before the EPDM goes down, so budget for that separately if it applies to your roof.
Derby EPDM Price Ranges by Roof Size and Condition
For a straightforward garage or small extension roof — roughly 10 to 20 square metres — most EPDM jobs in Derby fall somewhere between £900 and £1,800 fully fitted, covering strip-out, membrane and flashings. Larger extension or outbuilding roofs of 20 to 40 square metres typically run from around £1,800 up to £3,500, with bigger commercial areas priced per square metre once we’ve measured on site.
Rotten decking adds roughly £30–£50 per board replaced, and warm roof insulation typically adds £15–£30 per square metre depending on the thickness needed to meet current building regulations. Access equipment — a tower or scaffold, where a ladder or drone survey genuinely isn’t enough — is priced separately once we’ve seen the roof.
What Pushes the Price Higher
- Internal corners — each one requires a custom-formed EPDM detail
- Wall junctions and upstands — the flashing work at each junction takes time and materials
- Roof penetrations — soil pipes, extraction vents and rooflights each need individual sealing
- Poor deck condition — replacing rotted or damaged OSB decking adds cost before the EPDM goes down
- Access difficulty — a roof over a narrow side passage or above a conservatory takes longer to work safely
On a typical Derby extension in Mickleover or Alvaston — 28–35 m² with one internal corner, a soil pipe, and a parapet wall on one side — expect to add £100–£200 over the base rate for the extra detail work. We tell you exactly what that costs before we start, in writing. Roof shape, upstands, penetrations and what’s found under the old covering all move these figures, so a firm price always follows a site visit or drone survey rather than a phone estimate.
What’s Included When We Quote Your EPDM Roof
- Full strip-out of the failed felt, asphalt or old EPDM covering down to bare decking
- Replacement of rotten OSB or plywood decking sections found once the old covering is removed
- Firestone RubberCover EPDM membrane, bonded as a single sheet on garages, extensions, outbuildings and most domestic or small commercial roofs
- Hand-formed flashings at upstands, parapets and internal corners
- Dressing in around penetrations such as soil vent pipes, roof lights and existing outlets
- A free pre-quote survey, on foot or by drone, plus a written itemised quote before any work is booked
- A written workmanship guarantee and the installation paperwork mortgage surveyors or buyers typically ask for
Not Included / Costed Separately
- Warm roof insulation board — available and priced, but only fitted where it’s specified in the quote
- Scaffolding or a mobile access tower, added to the price only where the roof height or access makes it necessary
- Structural deck rebuilds beyond patching the rotten sections found on the day
- Supply and fit of new roof lights, soil stacks or outlets, where the existing ones need replacing rather than re-flashing
- Guttering, fascia or soffit repairs beyond the roof edge itself
From Enquiry to a Finished Rubber Roof
- Call or online enquiry: You describe the roof — garage, extension, outbuilding or commercial unit — along with a rough size, so we can plan the survey.
- Free survey, on foot or by drone: We visit within days and walk the roof directly, or fly our drone over it where access is tight or a physical climb isn’t practical, checking deck condition, penetrations, upstands and parapets.
- Written, itemised quote: You receive a quote broken down by material, labour and any extras — decking repair, warm roof insulation, scaffolding or an access tower — so nothing is added once work starts.
- Deck preparation: The old covering is stripped, any rotten OSB or plywood decking is replaced, and warm roof insulation board is fitted where agreed in the quote.
- EPDM installation: The Firestone RubberCover EPDM is rolled out and bonded as a single sheet wherever the roof size allows, with flashings hand-formed at upstands, internal corners and penetrations.
- Completion and guarantee paperwork: The site is cleared, your written workmanship guarantee is handed over, along with any documentation a mortgage surveyor or buyer would want to see.
How Does EPDM Compare to Felt and GRP Fibreglass?
Upfront price is only half the picture. The comparison that matters for most Derby homeowners is cost per year of protection, calculated across a realistic roof lifespan — not just the invoice on day one.
| EPDM Rubber | Torch-On Felt | GRP Fibreglass | |
|---|---|---|---|
| Typical lifespan | 25–50 years | 10–20 years | 20–30 years |
| Seams | Single sheet on most domestic roofs — few or no seams | Overlapping joints, a common failure point | Seamless once cured, but the gel coat can crack |
| Installation method | Cold-bonded adhesive, no naked flame on site | Heated with a blowtorch during fitting | Resin laminate, needs dry conditions to cure properly |
| Movement tolerance | Flexes with the deck through hot and cold weather | Can crack or blister as the deck moves | Rigid once cured, less forgiving of deck movement |
| Common use on Derby roofs | Garages, extensions, outbuildings, flat roof recovers | Older roofs, budget recovers | Balconies, walk-on areas, new-build |
Bitumen felt installed at around £50–£70 per m² totals roughly £1,000–£1,400 for a 20 m² garage roof, but with a lifespan of 10–20 years in Derby’s freeze-thaw climate, that roof will likely need replacing once — possibly twice — within 30 years. EPDM installed at £70–£100 per m² totals roughly £1,400–£2,000, and one professional installation lasts 40–50 years, meaning a single job covers most of a Derby homeowner’s ownership of the property. GRP fibreglass installed at £100–£150 per m² totals roughly £2,000–£3,000, with a lifespan of 25–40 years when correctly installed on a sound deck. Viewed over their full lifespans, EPDM comes out as the most cost-effective option overall, followed by GRP, with traditional felt the most expensive despite its lower initial cost.
The Guarantee Behind Every EPDM Roof We Fit
Our crew fits Firestone RubberCover EPDM as bonded-sheet installers, and every roof leaves with a written workmanship guarantee backed by our insurance rather than a verbal promise that the seams will hold. Getting the membrane on properly still depends on reaching the roof safely in the first place: our fitters hold IPAF cards for powered access platforms and PASMA cards for mobile towers, so a garage roof tucked behind a side return or several storeys up gets the right equipment rather than a ladder stretched past what it’s suited to.
Does EPDM Add Value to a Derby Property?
A well-installed EPDM roof is a positive, not a negative. The concern that flat roofs affect property values comes from the era when flat roofs meant felt — a material with a short lifespan and a reputation for leaking. That reputation doesn’t apply to a modern EPDM installation: mortgage surveyors and lenders know the difference, and a Firestone RubberCover installation with a written guarantee, correctly installed within the last few years, reads as evidence of a well-maintained property rather than a red flag.
If you’re selling a Derby property with an EPDM flat roof, have your written guarantee and installation paperwork ready before the survey, know the installation date and product specification, and if the roof is older and showing wear, a pre-sale survey and repair is a straightforward way to remove any issue before it reaches a buyer’s solicitor.
Customer Story: Summer House Roof, Allestree
When David started getting quotes for a new roof on his garden summer house — an 18 m² flat roof he’d used as a home office for years — he assumed felt was the only realistic option. We walked him through the numbers honestly: felt would come in cheaper on the day, but with a likely lifespan of 10–15 years he’d be facing the same job again before long. EPDM on the same roof came to around £1,400 — only a few hundred pounds more than felt — with a lifespan of 40–50 years and a 20-year workmanship guarantee behind it. “Once they explained the long-term cost, it was an easy decision. I’m not replacing that roof again,” David said. The installation was completed in a single day, with no disruption to the garden and no mess left behind.
Areas We Cover for EPDM Rubber Roofing
Derby is where most of our EPDM installations happen, and the city splits fairly evenly either side of the A38 — Chaddesden and Spondon sit on the east side, Mickleover and Allestree to the west, with Alvaston covering the south — so a free survey or drone inspection is quick to arrange wherever in that ring you are. We also take on EPDM flat roof work further out across Nottingham, Sheffield, Leeds, Manchester, Doncaster, Wakefield, Rotherham and York — call us on 01332-529704 to check availability for your postcode before booking a survey.

Frequently Asked Questions — EPDM Rubber Roof Cost Derby
How much does an EPDM rubber roof cost in Derby?
Most garage or small extension roofs (10–20 m²) run £900–£1,800 fully fitted, with larger roofs (20–40 m²) typically £1,800–£3,500. Decking repairs, warm roof insulation and access equipment are priced as extras once we’ve seen the roof, so treat these as starting bands rather than a fixed quote.
How long does an EPDM roof actually last?
Firestone RubberCover EPDM is generally rated for 25–50 years. Because it’s bonded as a single sheet on most domestic roofs, there are few or no seams to fail, which is the main reason it outlasts felt.
Do I need scaffolding for an EPDM roof?
Not always. We survey most roofs on foot or with a drone, and our fitters hold IPAF and PASMA cards so a mobile tower or powered platform can be used where a ladder isn’t suitable. Full scaffolding is only added to the price where the height or access genuinely calls for it.
What’s included in the price and what costs extra?
The quoted price covers strip-out, decking checks, the EPDM membrane and flashings, plus a written guarantee. Warm roof insulation, replacement of rotten decking beyond a normal patch, and any scaffolding or tower hire are itemised separately so you can see exactly what they add.
Can EPDM be fitted straight over my existing felt roof?
No — our process always strips the old covering back to bare decking first. This lets us check the deck for rot and gives the new membrane a sound surface to bond to, rather than covering up a problem underneath.
Is there a guarantee on the work?
Yes. Every EPDM installation comes with a written workmanship guarantee, backed by our insurance, and we can provide the installation paperwork mortgage surveyors or buyers ask for.
How long does fitting take?
A typical garage or small extension roof is usually finished within a day or two once decking and weather allow. Larger commercial roofs or ones needing significant deck repair take longer, and we’ll give you a realistic timescale in the written quote.
Do you cover areas outside Derby?
Yes. Alongside Derby and Derbyshire, we take on EPDM work across Nottingham, Sheffield, Leeds, Manchester, Doncaster, Wakefield, Rotherham and York — get in touch to check we cover your postcode before booking a survey.
