Felt flat roof installation and replacement using modern high-performance systems.
Symptoms & warning signs
- Surface chippings washed away leaving the felt exposed and weathering
- Cracking, crazing or brittleness across an ageing felt surface
- Blistering and bubbling where moisture is trapped between layers
- Laps and seams opening at the edges
- Water ingress below a garage, extension or outbuilding roof
Inspection & diagnosis
Every quote begins with an inspection. Where a roof is inaccessible, complex or storm-damaged, we can carry out a drone inspection to capture imagery and annotated findings before recommending works.

Typical scope of work
- Strip of the existing covering and inspection of the deck beneath
- Replacement of wet, delaminated or damaged decking boards
- Vapour control layer and insulation where a warm-roof build-up is specified
- Torch-on or high-performance built-up felt laid in the correct number of layers
- Mineral-finish cap sheet, with upstands and drip trims fully dressed
- Outlets, rainwater connections and abutment flashings formed and sealed
Timescale
A standard garage or extension felt roof is generally a one to two day job; larger or multi-level roofs take longer. Torch-on work needs dry conditions and safe working, so it is weather-dependent.
Guarantee & aftercare
Felt roofing carries our written workmanship guarantee alongside the manufacturer's warranty for the membrane system installed, both provided on completion.
Project evidence
Every job is photographed before, during and after the work, so you can see what was found, what was done and what it looks like finished — including the parts of the roof you cannot see from the ground. Those photographs are shared with you and, with permission, may be used as a case study.
