Why choose torch-on felt roofing in Royal Tunbridge Wells?

Torch-on felt suits property owners in Royal Tunbridge Wells 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 a large town like Royal Tunbridge Wells, flat roofs are commonly found on newer estates where the first extension roofs are now being replaced or low-rise post-war blocks of flats. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.

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?

  • Two- or three-layer reinforced bitumen membrane with staggered laps
  • Deck inspection with replacement of damaged boards
  • Mineral-finished cap sheet, upstands, outlets and edge trims
  • Vapour control layer and warm-roof insulation where needed

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.
