Flat Roofing: Rubber & Mineral Felt Roofs
Flat Roofing in Darlington: Seamless, Waterproof Systems Built to Last.
Modern EPDM rubber and mineral felt flat roofs for garages, extensions, dormers and porches across Darlington, seamless, waterproof and built to last.
The problem we solve
Why you might need flat roofing: rubber & mineral felt roofs.
Flat roofs fail because water has nowhere to run. Old felt blisters in the sun, splits in the frost, and soon you're collecting drips in buckets every time it rains. Patching a tired flat roof rarely lasts. The new felt soon joins the old in failing. A properly installed modern flat roof system, laid onto sound decking with the right falls, is the dependable fix.
Signs to look out for
Common signs this work is needed
- Blistering, bubbling or cracking across the felt surface
- Water pooling that doesn't drain away after rain
- Damp patches, staining or mould on the ceiling below
- Spongy or rotten decking that flexes underfoot
- Repeated repairs that only hold for a few months
- An old felt or bitumen roof that is well past its expected lifespan
What's included
A complete, in-house scope.
Old bitumen and felt flat roofs blister, crack and pool water over time, leading to leaks that damage ceilings and decoration below. DB Building & Roofing installs high-performance flat roofing across Darlington, using seamless EPDM rubber membranes and heavy-duty multi-layer felt systems engineered to shrug off standing water and British weather, so your garage, extension or dormer stays dry for years to come.
- Removal of degraded felt, rotten decking and any standing water
- Installation of 18mm structural OSB3 tongue-and-groove decking boards
- Seamless single-ply EPDM rubber membrane or heavy-duty multi-layer felt system
- Pre-formed kerb trims, gutter drip edges and wall upstands
- Insulation upgrades to eliminate internal condensation
- Integration with roof lanterns and rainwater drainage
