Why choose torch-on felt roofing in Yarm?
On larger roofs in Yarm 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.
Yarm's flat roofs are mostly on bungalows with flat-roofed side extensions and dormers, with plenty on 1960s and 1970s link-detached houses with flat-roofed garages and porches too. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county.

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?
- Mineral-finished cap sheet, upstands, outlets and edge trims
- Deck inspection with replacement of damaged boards
- Strip-off of the existing roof covering and removal of waste
- Hot-works checks and fire watch on every torch-on job
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 Yarm?
£1,450–£2,500 for a typical 18 m² garage roof in torch-on felt, at Yorkshire and the Humber 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.
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.
