Single-ply rubber membrane flat roofing for extensions, garages and bungalows. No seams, no joints to fail. Free surveys across Darlington and County Durham.
County Durham's wet climate demands a flat roof system with no weak points. EPDM is a single seamless sheet bonded to the deck — nothing to fail at joints, nothing to lift in frost.
One sheet bonded to the full deck. No laps, no seams, no joints — the failure points of every traditional felt system.
Remains flexible at -40°C. County Durham's freeze-thaw winters won't crack it at joints the way felt fails.
Best suited to areas over 20m². The larger the area, the more EPDM outperforms GRP on thermal movement.
The longest-lived domestic flat roof system available.
Annual inspection recommended. No recoating, no resealing, no retreatment.
18mm WBP ply deck with correctly graded falls built in before membrane installation.
“EPDM on our rear extension — properly installed with correct drainage falls. Original felt had been leaking for 3 years. Should have done it sooner.”
“Bungalow flat roof replaced with EPDM. No more puddles on the roof and no more ceiling damp. Exactly as quoted.”
“GRP was quoted cheaper elsewhere but they recommended EPDM for our larger area. Honest advice that we've since confirmed was correct.”
All quotes are free, written and itemised before work begins. We cover Darlington and approximately a 20-mile radius including Stockton-on-Tees, Middlesbrough, Newton Aycliffe, Bishop Auckland, Northallerton, Yarm, Eaglescliffe, Barnard Castle, Richmond and all surrounding villages. No call-out charge for the survey visit, no obligation to proceed.
National roofing firms typically pass enquiries to local subcontractors — you don't know who will turn up or what their standard of work is. We are a Darlington-based contractor. Our team covers the same routes every week, knows the specific housing stock and common failure patterns across County Durham and North Yorkshire, and carries the most common repair materials on the vehicle. Most repair calls result in a completed job on the first visit rather than a return trip for materials.
We are registered with the National Federation of Roofing Contractors, carry £5m public liability insurance on all work, and provide a written 10-year workmanship guarantee on all replacement and major repair work. Evidence of insurance is available on request before any work begins. Call 01325 000 000 for a free, no-obligation quote.
County Durham's wet climate makes the choice between EPDM and GRP for Darlington flat roofs an important one. Both systems significantly outperform felt — the question is which is better suited to the specific roof. EPDM's single-ply flexibility means it handles larger roof areas and complex geometries better than the stiffer GRP system. For standard extension roofs up to 40m², GRP is typically the first choice — the finish is slightly cleaner and the system is marginally simpler to install on standard rectangular areas. For larger sections, bungalow roofs, or areas with complex geometry, EPDM is often the better technical specification.
The most common EPDM applications we carry out in Darlington and the surrounding area are: bungalow flat roof sections (50–80m², too large for GRP in most cases), garage flat roofs with poor access where EPDM's flexibility simplifies installation, and properties with irregular roof geometry where a single flexible sheet is easier to dress around obstacles than rigid GRP panels. We survey and specify before any flat roof installation in Darlington — the correct system is confirmed at survey, not assumed from the description.
We are a Darlington-based roofing contractor covering County Durham and North Yorkshire. Every job we take on across the area is handled by our own team — not passed to a subcontractor we have no control over. We know the specific housing stock, the common failure patterns, and the correct material specifications for properties across the region. This local knowledge directly affects the quality of diagnosis and the durability of the work we carry out.
Every quote we provide is free and comes with no obligation to proceed. We get on the roof before quoting — measuring the area, inspecting the structure, and confirming the correct materials. The written quote you receive is a fixed price for the specific work described, not an estimate subject to revision once we start. We don't quote for the easy parts and add the rest later.

EPDM (ethylene propylene diene monomer) is a single-ply rubber membrane for flat and low-pitch roofs. A single sheet is bonded to the roof deck with no seams — unlike felt systems which fail at joints.
A correctly installed EPDM system typically lasts 30–50 years. County Durham's wet climate makes EPDM's seamless construction particularly valuable — no joints to fail in wet conditions.
Both outperform felt significantly. EPDM is more flexible under thermal movement, better for larger areas over 40m². GRP is stiffer with a cleaner finish, better for most standard extensions. For larger bungalow roof areas, EPDM is often the better technical specification.
A typical 20–30m² extension costs £1,500–£2,800 installed. Larger bungalow sections of 50–80m² run to £3,500–£6,000. We provide itemised written quotes after a free survey.
Yes. EPDM remains flexible at -40°C — far below anything County Durham experiences. Excellent for Darlington's freeze-thaw winters.
Yes. EPDM carries a 20-year manufacturer guarantee on the membrane plus our 10-year workmanship guarantee, both in writing.
Sometimes. We inspect the existing deck first. If the ply deck is sound and dry, EPDM can go over it. If the deck has absorbed moisture or is soft, it needs replacing first.
We survey, specify and install EPDM across Darlington and County Durham. No call-out fee.
