Torch-on felt roofing in Glasgow

Replacing an old felt roof in Glasgow? Modern torch-on systems are far tougher than the felt many people remember. We strip the existing covering, repair the deck, add warm-roof insulation where needed and lay new membranes with staggered laps. Guide prices are online, and the fixed price comes after our free survey.

Why choose torch-on felt roofing in Glasgow?

On larger roofs in Glasgow 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.

Glasgow's flat roofs are mostly on lock-up garage blocks on estates, with plenty on low-rise post-war blocks of flats too. 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.

How much does a torch-on felt roof cost in Glasgow?

For Glasgow we use Scotland rates: £1,450–£2,500 is the guide for a typical 18 m² garage roof in torch-on felt, VAT included. The fixed price comes after a free survey for new and replacement roofs.

How long does a torch-on felt roof last, and what is the guarantee?

A modern torch-on roof typically lasts 15 to 25 years, and high-performance systems with better membranes can last longer. That is a big step up from older felt roofs, which were often single-layer, unreinforced or poorly bonded.

What shortens the life of a felt roof is usually visible: mineral chippings worn away so the bitumen is exposed to sunlight, blisters where moisture was trapped, split laps, and upstands that have slumped or pulled away from the wall. Ponding speeds all of this up.

Manufacturer material guarantees are available on many specified torch-on systems; they often depend on a particular build-up and registration, which we handle where the system allows. Every re-roof also comes with our written workmanship guarantee, the length of which is stated in the quote, and insurance-backed options can be discussed. Our flat roof lifespan guide compares felt with the other systems.

What's included?

  • Hot-works checks and fire watch on every torch-on job
  • Mineral-finished cap sheet, upstands, outlets and edge trims
  • Strip-off of the existing roof covering and removal of waste
  • Vapour control layer and warm-roof insulation where needed

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.

How much does a torch-on felt roof cost in Glasgow?

£1,450–£2,500 for a typical 18 m² garage roof in torch-on felt, at Scotland guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Can torch-on felt be laid in wet weather?

Not in rain or on a wet deck, because moisture trapped under the membrane causes blisters. Light cold weather is usually workable, but we will postpone rather than lay on a damp surface.

Is torch-on suitable for a block of flats?

Yes, layered bitumen systems are widely used on blocks of flats and commercial buildings. Larger roofs often use three layers and insulation, with hot works planned around residents.
