Recognise any of these?

A new torch-on felt roof can fix them

Most roofs fail quietly. A hairline crack or lifted lap lets water in, and by the time you see a damp patch on the ceiling, the deck below may already be saturated. Catching it early is always cheaper than leaving it.

A persistent leak

Water is tracking into rooms or staining a garage ceiling after it rains.

A fully bonded three-layer membrane with no weak points for water to find.

Blistering or cracking

Your existing felt is lifting, bubbling or splitting across the surface.

A fresh three-layer system, welded together under controlled heat.

Pooling water

Water is sitting on your roof and not draining away after it rains.

Correct falls are built in during installation, directing water to the outlets.

Condensation

Rooms below the roof suffer cold spots or condensation on the ceiling.

We can combine the new covering with a warm-roof insulation upgrade in one visit.

Failed repairs

Temporary fixes keep coming back and the same areas leak again and again.

Replacing the whole covering in one go ends the cycle of patch repairs for good.

Age and weathering

Your felt roof is over 15 years old with no recent inspection or maintenance.

A fresh, fully guaranteed covering built to last another 15 to 25 years.

The right solution

Torch-on felt: a proven system for flat roofs

A torch-on felt system uses three layers of modified bitumen felt, each melt-welded to the one below with a blowtorch. That creates a fully bonded, waterproof membrane with no cold joins and no weak points: a vapour control layer, a reinforced underlay, and a UV-stable mineral cap sheet.

Installed correctly, a three-layer torch-on felt roof is tough, long-lasting and cost-effective. We control torch temperatures throughout, check every lap on completion and run a full water test before leaving site.

As Icopal-approved contractors, every felt installation follows a strict quality process. The result is a watertight, durable roof backed by our 10-year workmanship guarantee.

  • Three layers heat-welded, no cold joins or weak points
  • Correct falls built in to stop ponding
  • UV-stable mineral cap sheet for a clean, lasting finish
  • Water-tested and photographed on completion

Questions

Torch-on felt roofing - your questions answered

A correctly installed three-layer felt roof typically lasts 15 to 25 years. The quality of installation is the single biggest factor. A single-layer or poorly applied felt roof will fail much sooner, which is why the system and the contractor both matter.
For the right application, yes. A three-layer system is a proven and reliable solution. For complex roof shapes or very large open spans, GRP or EPDM may be a better fit. We’ll advise honestly on survey based on your specific roof.
Sometimes. We assess the existing deck and substrate on survey. If it’s structurally sound and level, an overlay may be possible. If the deck or insulation has been compromised, we’ll recommend a full strip.
The top layer protects the felt from UV degradation, adds grip for occasional foot access and gives a clean, professional finish. It’s one of the key differences between a quality installation and a budget one.
Yes. We can upgrade to a warm roof specification during the re-roof, adding PIR insulation above the deck to improve thermal performance and prevent condensation.
Prices vary by size and whether a strip or overlay is required. You’ll get a fixed written quote after the free survey, with no hidden extras and no surprises.
