When it comes to EPDM Rubber Roofing, KU Designs offers an unrivalled level of expertise and durability for North East properties. Traditional felt roofs struggle with the unpredictable North East climate. At KU Designs, we specialise in high-performance EPDM Rubber Roofing, a seamless, cold-applied solution designed to protect homes across Teesside, Durham, and Sunderland for over half a century.
UV-resistant and built to outlast traditional felt by decades. It’s the last flat roof you’ll ever need.
100% Seamless Membrane. Applied in large, single-ply sheets to eliminate joins, removing the #1 cause of flat roof leaks.
We don’t use dangerous torches or heat. Our EPDM is safely bonded using high-strength adhesives.
Unlike porous felt or tiles, the smooth EPDM surface is chemically inert, preventing moss growth and keeping your roof looking brand new for decades.
As the leading flat roof specialist in the North East, KU Designs provides high-performance EPDM installation and repair alongside bespoke exterior builds. From rubber roofing in Teesside to precision skylight fitting, we bring 16 years of trade expertise to every home improvement project in Middlesbrough, Stockton, and beyond.
Traditional torch-on felt has been the North East standard for decades, but it wasn’t built for today’s extreme weather. Over time, the UK’s fluctuating temperatures and heavy rain cause felt to become brittle, leading to cracks, splits, and the inevitable “drip through the ceiling.” Because felt is applied in multiple rolls, every seam is a potential weak spot for water to get in.
We’ve replaced the “patch and repair” cycle with a permanent solution. EPDM Rubber Roofing (Ethylene Propylene Diene Monomer) is a high-performance synthetic rubber membrane that remains flexible from -40°C to +140°C.
No Cracking: Unlike felt, EPDM expands and contracts with your building without tearing.
No Rotting: It is completely inert and does not support the growth of moss or algae.
No Leaks: Most residential roofs can be covered with a single, custom-cut sheet, eliminating those risky seams entirely.
UV & Ozone Resistant: Built to withstand the North East’s extreme temperature swings without degrading.
Highly Flexible: Moves naturally with your building to prevent the cracking common in old felt roofs.
Fit & Forget: Once installed, EPDM requires virtually zero upkeep compared to traditional materials.
Sustainable Choice: Fully recyclable and manufactured with a low environmental impact.
No Weak Spots: Large sheets eliminate field seams—the #1 cause of flat roof failure.
Ultimate Waterproofing: 100% seamless barrier, ensuring there are literally no joins for water to penetrate, even during heavy North East downpours.
A leaking flat roof shouldn’t be a source of stress. Whether you’re managing a residential extension in Darlington, a commercial unit in Hartlepool, or a garage conversion in Middlesbrough, KU Designs delivers premium EPDM protection that stands the test of time.
Ditch the unreliable contractors and partner with a roofing specialist that understands the letting industry. We offer swift, high-quality flat roof assessments and repairs, providing the clear communication and professional results that landlords and agents expect.
We don’t do ‘sales pitches’ and we don’t hide behind jargon. If you’re investing in a new roof, you deserve to know exactly how it’s being built and why we use the gear we do. From the way we bond the EPDM to the structural timber work underneath, everything is done to instructor-level standards—no corners cut, no bodge jobs. If your question isn’t in the list below, just give Kieran a call and he’ll give you the answer.
Unlike traditional felt roofs that can fail within 10 years, our BBA-approved EPDM systems have a life expectancy of over 50 years. It’s a ‘once-and-for-all’ solution for your property.
Yes. Because Kieran is a certified EPDM instructor and we use premium-grade materials, we provide a full 20-year watertight guarantee on all new installations as standard
In some cases, yes—but as structural carpentry specialists, we prefer to inspect the decking first. We ensure the timber foundation is 100% sound before sealing, as this is the key to a roof that lasts half a century.
While the initial cost is slightly higher than felt, the ‘cost-per-year’ is significantly lower. When you factor in the lack of maintenance and the 50-year lifespan, EPDM is the most cost-effective flat roof investment on the market.
EPDM is an inert material, meaning it remains flexible from -40°C to +150°C. Unlike felt or bitumen, which becomes brittle and cracks during thermal expansion and contraction, our rubber membranes stretch and move with your building, eliminating the risk of stress-fractures.
Many contractors use thinner, 0.5mm membranes. We exclusively install 1.2mm or 1.5mm heavy-duty EPDM. This thickness provides superior puncture resistance and allows us to achieve the precision detailing required around roof lanterns and complex gully systems.
Not a penny. We offer free, honest surveys across Teesside. We’ll get on the roof, check the state of the boards, and give you a proper breakdown of what’s needed. No pressure, just a fair price for a top job.
There’s no comparison. Traditional felt has seams that eventually peel and leak; EPDM is a single, seamless sheet of high-grade rubber. It doesn’t crack in the sun, it doesn’t rot, and moss won’t grow on it. It’s the best stuff on the market, period.
Most domestic flat roofs—like a standard garage or extension—are stripped, timber-checked, and sealed in a single day. We don’t mess about; we get in, get the job done to a high standard, and leave the site spotless.
Virtually none. Because it’s a smooth, non-porous surface, dirt and grit usually just wash off when it rains. You don’t need to paint it or stone-chip it. If it gets a bit dusty, a quick splash with a garden hose is all it ever needs.
he beauty of EPDM is that it’s easily repairable. If you drop something sharp and puncture it, we don’t have to replace the whole roof. We can chemically bond a patch over the top that becomes part of the original sheet, keeping it 100% watertight again.
We took this stunning new-build garden room to the next level with a sleek, industrial-grade EPDM rubber roofing solution. Moving away from traditional materials, we provided a clean, modern finish that ensures this outdoor space remains 100% watertight and maintenance-free for decades to come. A factory-standard finish for a premium backyard retreat.
Faced with a failing, saturated felt roof in Middlesbrough, we provided a complete high-performance upgrade. We stripped the old, heavy layers back to the joists to install a fresh, structurally sound base. The result is a clean, ultra-durable garage roof that not only looks superior but adds genuine value and long-term security to the property.
Natural Light Integration. We transformed this flat roof in Stockton by combining high-performance EPDM with modern roof light technology. By cutting custom apertures and installing thermally efficient glass units, we flooded the living space below with natural light without compromising the roof’s structural integrity.
We were called out to a property in County Durham to tackle a long-standing leak that traditional patching couldn’t fix. We stripped back the failed, saturated felt and replaced it with a heavy-duty, single-ply EPDM system. By addressing the structural dampness and installing a seamless rubber barrier, we turned a stressful maintenance issue into a 50-year-certified success story.
