Torch-on felt roofing in Great Yarmouth

Torch-on felt in Great Yarmouth 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 Great Yarmouth?

On larger roofs in Great Yarmouth 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.

In a large town like Great Yarmouth, flat roofs are commonly found on terraced streets with flat-roofed rear kitchens and bathrooms or low-rise post-war blocks of flats. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.

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 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.

Is torch-on felt better than the old felt roofs?

Yes, considerably. Modern torch-on membranes are polymer-modified and polyester-reinforced, laid in bonded layers, and typically last much longer than the older felt systems they replace.

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.
