The investment for a torch-on felt flat roof depends on structural deck condition, number of layers, and whether warm-deck insulation is required:
| Roof Application | Typical Area | Estimated Cost (Inc. VAT) | Standard Duration |
|---|---|---|---|
| Single Garage Re-Felting (3-Layer) | 18 – 24 m² | £1,200 – £1,900 | 1 – 2 Days |
| Cold Deck Extension Felt | 20 – 35 m² | £1,500 – £2,500 | 1 – 2 Days |
| Warm Deck Felt Extension (120mm PIR) | 20 – 40 m² | £2,400 – £3,800 | 2 Days |
| Dormer Window Felt Replacement | 6 – 12 m² | £750 – £1,400 | 1 Day |
A standard domestic torch-on felt installation takes 1 to 2 working days. Our structured 4-phase process ensures complete weather-tight safety throughout:
Applying torch-on membranes demands strict fire mitigation controls. Our certified roofers operate under stringent hot-works permit procedures, equipped with fire extinguishers and conducting continuous thermal watch protocols following gas torch application. All materials meet fire resistance standards governing roofs near property boundaries.

Clear Answers
Everything you need to know about modern 3-layer torch-on felt roofs, costs, lifespan, and safety standards.
A professionally installed 3-layer torch-on felt roof using SBS-modified elastomeric polyester bitumen lasts 20 to 25 years. Modern felts are far superior to historic rag-felts because the polyester core will not rot, crack, or become brittle under seasonal British freeze-thaw cycles.
The average bitumen felt roof replacement cost is the most affordable of all flat roofing options, typically ranging from £55 to £85 per m² for cold decks and £110 to £150 per m² for insulated warm roofs (including timber deck replacement), delivering excellent value for money.
Yes. Our roofers are certified in hot-works safety and follow strict fire prevention protocols complying with Approved Document B (Fire Safety). Around combustible details like timber fascias or UPVC windows, we apply cold-applied or self-adhesive carrier sheets.
Torch-on mineral felt easily handles routine maintenance traffic, such as gutter cleaning or window washing. For high-traffic roof terraces or balconies, we install heavy-duty promenade tiles or rubber walkway pads to prevent granule displacement.
The mineral cap sheet is the top protective layer impregnated with crushed slate granules. It serves two vital functions: shielding the underlying bitumen from damaging ultraviolet solar radiation, and providing an attractive, weather-resistant finish in dark charcoal or green.
