Why choose torch-on felt roofing in Ashton-under-Lyne?

Torch-on felt suits property owners in Ashton-under-Lyne who want a dependable, layered roof without paying the top price per square metre. With two or three bonded layers, a single small defect in one sheet need not lead to a leak, which is a real advantage on larger roofs that are hard to inspect often.

Around Ashton-under-Lyne, flat roofs are common on lock-up garage blocks on estates and on newer estates where the first extension roofs are now being replaced. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.

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?

  • Strip-off of the existing roof covering and removal of waste
  • Mineral-finished cap sheet, upstands, outlets and edge trims
  • Vapour control layer and warm-roof insulation where needed
  • Two- or three-layer reinforced bitumen membrane with staggered laps

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a torch-on felt roof cost in Ashton-under-Lyne?

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

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.

Why does my felt roof have blisters?

Blisters usually form when moisture or air trapped beneath the felt expands in the sun. A few small, intact blisters may be monitored, but widespread or split blisters point to a repair or replacement.
