Torch-on felt roofing in Cheltenham

Replacing an old felt roof in Cheltenham? Modern torch-on systems are far tougher than the felt many people remember. We strip the existing covering, repair the deck, add warm-roof insulation where needed and lay new membranes with staggered laps. Guide prices are online, and the fixed price comes after our free survey.

Why choose torch-on felt roofing in Cheltenham?

Torch-on felt is widely specified for blocks of flats and HMOs, in Cheltenham as elsewhere, because the system is well understood, widely repairable and governed by a British Standard code of practice. Three-layer builds with insulation are common on larger, multi-occupied roofs.

In a large town like Cheltenham, flat roofs are commonly found on shops with flat-roofed rear stores below flats or low-rise post-war blocks of flats. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.

How much does a torch-on felt roof cost in Cheltenham?

At South West guide rates, a typical 18 m² garage roof in torch-on felt comes to £1,550–£2,700 including VAT. The fixed price comes after a free survey for new and replacement roofs.

Should I choose torch-on felt or a different flat roof system?

Choose torch-on felt when you want a proven, layered system at a sensible price, particularly on larger roofs, blocks of flats and commercial buildings where several layers give useful redundancy. It is a weaker choice where hot works are hard to manage safely.

For: generally lower cost per square metre; two or three layers, so a single defect in one layer need not cause a leak; tough mineral finish; long track record and a British Standard code of practice; repairs can be made with compatible materials.

Against: needs a naked flame unless a cold-applied or self-adhesive alternative is used; shorter typical life than EPDM or GRP; the finish is functional rather than decorative; more laps to detail than a single sheet.

On small domestic roofs near timber, EPDM avoids the torch entirely. GRP gives a harder, neater surface. For an overlay, a liquid-applied system is often simpler. Large commercial roofs may suit single-ply, and older buildings may suit mastic asphalt. See our comparison guide.

What's included?

  • Vapour control layer and warm-roof insulation where needed
  • Hot-works checks and fire watch on every torch-on job
  • Deck inspection with replacement of damaged boards
  • 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.

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.

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.
