Why choose torch-on felt roofing in Porthcawl?

For a commercial roof in Porthcawl, such as a shop, surgery or club, torch-on felt offers a hard-wearing mineral finish that takes occasional maintenance traffic. Phased work keeps part of the building weathertight while the rest is re-roofed, so the business can usually keep trading.

In and around Porthcawl, flat roofs are typically found on newer estates where the first extension roofs are now being replaced, and on 1930s semis with flat-roofed garages and kitchen extensions. 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.

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?

  • 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 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.

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

£1,400–£2,400 for a typical 18 m² garage roof in torch-on felt, at Wales guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.

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.
