Torch-on felt roofing in Vale of Leven

Across West Dunbartonshire, including Vale of Leven, we use torch-on felt on roofs where a proven, multi-layer system makes sense. The surveyor checks the deck, the falls and any timber near the edges before recommending two or three layers, and every detail is set out in your fixed written quote.

Why choose torch-on felt roofing in Vale of Leven?

On larger roofs in Vale of Leven with poor falls, torch-on felt pairs well with tapered insulation, which builds the fall into the insulation boards. That deals with ponding properly while adding insulation, rather than patching the low spots and waiting for the next leak.

Around Vale of Leven, flat roofs are common on 1930s semis with flat-roofed garages and kitchen extensions and on bungalows with flat-roofed side extensions and dormers. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.

Should I choose torch-on felt or a different flat roof system?

Choose torch-on felt when you want a proven, layered system at a sensible price, particularly on larger roofs, blocks of flats and commercial buildings where several layers give useful redundancy. It is a weaker choice where hot works are hard to manage safely.

For: generally lower cost per square metre; two or three layers, so a single defect in one layer need not cause a leak; tough mineral finish; long track record and a British Standard code of practice; repairs can be made with compatible materials.

Against: needs a naked flame unless a cold-applied or self-adhesive alternative is used; shorter typical life than EPDM or GRP; the finish is functional rather than decorative; more laps to detail than a single sheet.

On small domestic roofs near timber, EPDM avoids the torch entirely. GRP gives a harder, neater surface. For an overlay, a liquid-applied system is often simpler. Large commercial roofs may suit single-ply, and older buildings may suit mastic asphalt. See our comparison guide.

What's included?

  • Strip-off of the existing roof covering and removal of waste
  • Hot-works checks and fire watch on every torch-on job
  • Mineral-finished cap sheet, upstands, outlets and edge trims
  • Deck inspection with replacement of damaged boards

Building standards in Scotland

In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.
