Flat roofs are everywhere in Kendal. From the single-storey extensions on Victorian terraces along Highgate and Stricklandgate to garage blocks across Heron Hill and Hallgarth, and commercial premises throughout the town centre — flat roofing is a critical part of the town's building fabric. At Mr Roofer Kendal, we specialise in diagnosing and repairing every type of flat roof failure, using modern materials that deliver decades of reliable, watertight performance.
The South Lakes climate is particularly punishing for flat roofs. Kendal's annual rainfall exceeds 1,200mm, and the combination of persistent moisture, freeze-thaw cycles, and UV exposure during summer months creates the perfect conditions for accelerated flat roof deterioration. Traditional felt coverings — which were standard on extensions and garages built from the 1960s through the 1990s — typically last 10 to 15 years before showing signs of failure. Blistering occurs when trapped moisture expands during warm weather, cracking develops at upstand junctions where thermal movement stresses the membrane, and ponding water gradually breaks down the bitumen surface until leaks develop. Our flat roof repair service addresses every one of these failure modes with permanent, engineered solutions.
When repairing or replacing flat roofs in Kendal, we use three principal systems depending on the specific application and client requirements. GRP fibreglass roofing creates a completely seamless, fully bonded membrane that eliminates joints — the most common point of failure on flat roofs. It's ideal for garage roofs, dormer tops, and smaller extensions where a lifetime solution is wanted. EPDM rubber roofing offers exceptional flexibility and longevity, with a proven track record exceeding 40 years in service — particularly suited to larger flat areas on commercial buildings and schools. For repairs to existing felt systems where a full replacement isn't necessary, we use high-performance torch-on modified bitumen membranes that massively outperform traditional pour-and-roll methods.
Many flat roof problems are invisible from ground level until water is already coming through the ceiling. We offer free flat roof inspections for Kendal homeowners, checking for early signs of deterioration including membrane splitting, failed upstands, blocked drainage outlets, and insulation degradation. Catching problems early saves significant money — a targeted repair costing a few hundred pounds can prevent water damage running into thousands. We provide honest assessments: if your flat roof has years of life remaining, we'll tell you. Our reputation across Kendal and the South Lakes is built on trust, not upselling.
Every flat roof material we install in Kendal is selected for its proven performance in heavy-rainfall, high-exposure environments. The South Lakes climate doesn't forgive cheap materials or poor installation — what works in the drier east of England often fails within years here. We specify premium systems from manufacturers who understand northern conditions and back their products with meaningful guarantees.
Our GRP fibreglass installations use Polyroof, Topseal, and Cure It resin systems — all BBA-certified and specifically formulated for UK weather conditions. The system comprises a polyester resin reinforced with chopped strand mat, creating a rigid, fully bonded membrane with no joints or seams. This is critical for Kendal's climate because joints are the primary failure point on flat roofs. Once cured, GRP is completely waterproof, UV-stable, and can be walked on safely — making it ideal for balconies, roof terraces, and maintenance access routes.
For larger flat roof areas, we install Firestone RubberGard and ClassicBond EPDM membranes in single sheets up to 15 metres wide — eliminating on-site joints entirely. EPDM has been proven in service for over 50 years worldwide and offers exceptional resistance to UV degradation, ozone, and extreme temperature cycling. The material remains flexible down to minus 45 degrees Celsius, meaning it won't crack or split during Cumbria's harshest winters.
Where existing felt flat roofs need repair or overlay, we use SBS-modified bitumen torch-on membranes from manufacturers including IKO and Bauder. These high-performance felts contain synthetic rubber modifiers that dramatically improve flexibility, tear resistance, and lifespan compared to traditional oxidised bitumen felt. Applied using controlled heat, the membranes form a fully welded, monolithic covering that self-seals around fixings and penetrations.
Beneath every flat roof membrane, the supporting structure and insulation are equally important. We use Kingspan and Celotex PIR insulation boards to achieve U-values that comply with current Building Regulations, and install tapered insulation systems that create positive falls across the roof surface — eliminating the ponding water that destroys flat roofs prematurely. Structural decking uses marine-grade plywood or OSB3 boards rated for humid conditions, ensuring the deck itself resists moisture throughout its service life.
We provide flat roof repairs throughout Kendal and the surrounding South Lakes area. Within the town, we cover every neighbourhood — from the commercial properties around the Westmorland Shopping Centre and Stramongate to residential areas in Heron Hill, Hallgarth, Sandylands, Castle Hill, and Oxenholme.
