We specialize in cold-applied, seamless membranes that eliminate fire risk and ensure operational continuity for commercial assets across Teesside, Durham, and Sunderland. Designed for high-traffic and large-span environments, our systems offer a 50-year service life, providing the ultimate long-term protection for your business infrastructure.
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.
KU Designs is the North East’s specialist contractor for high-performance EPDM roofing systems and large-scale flat roof renewals. From industrial-grade rubber roofing in Teesside to complex structural glazing and skylight integration, we provide 16 years of instructor-level expertise to commercial projects across Middlesbrough, Stockton, and the wider region. Our focus is on delivering durable, zero-flame solutions that protect your building’s asset value and ensure long-term operational continuity.
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 (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 understand that operational continuity is your priority. Our EPDM systems are cold-applied, requiring zero ‘hot works’ or open flames. This eliminates fire risks, simplifies your health and safety protocols, and often leads to lower insurance premiums. Installations are fast and quiet, ensuring your tenants or operations remain undisturbed.
Every commercial project is overseen by an industry instructor, ensuring 100% adherence to Building Regulations and fire safety standards. We provide full technical documentation and 20-year warranties that protect the building’s asset value and satisfy surveyor requirements during future divestment or leasing.
Stop guessing the condition of your roof. We provide 4K drone-assisted roof audits for large-scale commercial units. Our high-resolution aerial imaging identifies thermal leaks, drainage blockages, and structural fatigue, allowing for data-driven maintenance decisions rather than reactive, costly repairs.
A compromised commercial roof is more than just a leak, it’s a risk to your stock, machinery, and health and safety compliance. At KU Designs, we specialize in the technical repair and restoration of industrial flat roofs across the North East. Utilizing 4K drone diagnostics, we pinpoint structural fatigue and membrane breaches that traditional inspections often miss. We ensure that repairs are not just temporary fixes, but strategic interventions designed to extend the lifecycle of your existing roof.
We’ve brought specialist drone technology to our Rubber Roofing Teesside service to give you the most accurate assessment possible. Whether you’re looking for a free survey as part of a new EPDM installation or a detailed, standalone inspection for your insurance or peace of mind, our high-res aerial imaging catches what the human eye misses.
We provide a bird’s-eye view of your property’s structural health, identifying leaks, blocked gullies, and timber fatigue in minutes. It’s the safest and most efficient way to plan your flat roof project in Middlesbrough, Stockton, and across the North East
Whether it’s a leaking garage roof or a bespoke new build, we’re on hand to provide a free, no-obligation survey and a straight-talking quote.
