Torch-on felt roofing in Tamworth

Torch-on felt in Tamworth 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 Tamworth?

Torch-on felt suits property owners in Tamworth 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.

In and around Tamworth, flat roofs are typically found on shops with flat-roofed rear stores below flats, and on bungalows with flat-roofed side extensions and dormers. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds.

Does replacing a felt roof mean upgrading the insulation?

Usually, yes, when the roof is over a heated space and more than half of it is being re-covered. In England, Wales and Northern Ireland that is renovation of a thermal element, which should be brought towards the renovation U-value where feasible; a Scottish project goes through the council's building standards service, which confirms whether a warrant applies.

A felt replacement is a good point to switch to a warm roof, with insulation laid above the deck under the new membranes. On larger roofs, tapered insulation can also correct poor falls that have caused ponding, which a patch repair cannot fix. Raising the roof level affects upstands and door thresholds, so we check heights at survey. Any approval is arranged by us as part of the job, and the building regulations page sets out the rules by nation.

What's included?

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

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 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.

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.
