Torch-on felt roofing in Deeside

Across Flintshire, including Deeside, we use torch-on felt on roofs where a proven, multi-layer system makes sense. The surveyor checks the deck, the falls and any timber near the edges before recommending two or three layers, and every detail is set out in your fixed written quote.

Why choose torch-on felt roofing in Deeside?

Torch-on felt is widely specified for blocks of flats and HMOs, in Deeside 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.

Deeside's flat roofs are mostly on shops with flat-roofed rear stores below flats, with plenty on low-rise post-war blocks of flats too. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.

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

At Wales guide rates, a typical 18 m² garage roof in torch-on felt comes to £1,400–£2,400 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?

  • Hot-works checks and fire watch on every torch-on job
  • Strip-off of the existing roof covering and removal of waste
  • Two- or three-layer reinforced bitumen membrane with staggered laps
  • Deck inspection with replacement of damaged boards

Building regulations in Wales

The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

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.

Can torch-on felt be laid in wet weather?

Not in rain or on a wet deck, because moisture trapped under the membrane causes blisters. Light cold weather is usually workable, but we will postpone rather than lay on a damp surface.
