Torch-on felt roofing in Llanelli

Across Carmarthenshire, including Llanelli, 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 Llanelli?

On larger roofs in Llanelli 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 town like Llanelli, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or lock-up garage blocks on estates. 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.

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
  • Strip-off of the existing roof covering and removal of waste
  • Vapour control layer and warm-roof insulation where needed
  • 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.

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

£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.

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.

Can I paint or coat an old felt roof?

Reflective or liquid coatings can extend the life of a sound felt roof, but they will not fix wet insulation, a rotten deck or poor falls. A survey shows whether coating or replacement makes more sense.
