Torch-on felt roofing in Tullibody

Torch-on felt in Tullibody is a layered roof: an underlay, sometimes an intermediate sheet, and a mineral-faced cap sheet, each heat-bonded to the one below. It is generally the most economical of the main systems and suits garages, extensions and larger roofs on blocks and shops alike.

Why choose torch-on felt roofing in Tullibody?

Where a flat roof in Tullibody already has a felt covering and the building owner wants like-for-like, torch-on is the natural replacement. The old roof is stripped, the deck checked and the new layers laid, often with warm-roof insulation added when the space below is heated.

In a town like Tullibody, flat roofs are commonly found on bungalows with flat-roofed side extensions and dormers or lock-up garage blocks on estates. 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.

Is torch-on roofing safe, and what is the difference between two- and three-layer systems?

Yes, torch-on is safe when hot works are properly controlled, because most roof fires linked to torching start at hidden timber or debris near edges and upstands, not on the open roof. Our teams follow a hot-works routine on every job:

  • check eaves, fascias, soffits and wall cavities for timber, nests and debris before lighting a torch;
  • use a cold-applied or self-adhesive membrane, rather than a flame, at edges, against combustible materials and in tight details;
  • keep fire extinguishers on the roof and the gas bottles secured and away from the work;
  • stop torching well before the team leaves, then carry out a fire watch so smouldering is spotted while people are still on site.

As for layers, a two-layer system (underlay plus cap sheet) is common on domestic roofs such as garages and extensions. A three-layer system adds an intermediate sheet, giving more thickness and redundancy, and is often specified on larger, commercial and multi-occupied roofs. The right choice depends on the size and use of the roof and the system's requirements, so we set it out in the quote.

Near a boundary, the external fire performance of the tested build-up, such as a BROOF(t4) classification, can also matter, and we check it where it applies.

What's included?

  • Deck inspection with replacement of damaged boards
  • Two- or three-layer reinforced bitumen membrane with staggered laps
  • Hot-works checks and fire watch on every torch-on job
  • Strip-off of the existing roof covering and removal of waste

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 long does it take to lay a torch-on felt roof?

A garage roof typically takes one to two days and an insulated extension two to three. Larger roofs and blocks are phased over longer, with each area made weathertight before the team leaves.

Can torch-on felt go over an existing felt roof?

Sometimes, if the old roof is dry, well bonded and the deck is sound. Often stripping is better, because overlaying can trap moisture and hide rot; our guide to overlay or strip explains how we decide.
