Question 1

What’s the lifespan of a torch‑on felt roof?

Accepted Answer

A well-installed high-performance torch‑on felt roof typically delivers 15 to 30 years of protection. Regular inspections, proper drainage, correct ventilation and strong material quality will help maximise how long it lasts.

Question 2

Is it safe to install torch‑on felt myself?

Accepted Answer

Due to the risks of using open flame tools, you need formal training, adequate insurance, and compliance with British Standards such as BS 8217 and BS 8747. For these reasons, installation is best carried out by certified professionals.

Question 3

Can torch‑on roofing felt be repaired?

Accepted Answer

Minor issues such as small tears, seam cracks or damaged granules can often be patched locally using torch‑bond or adhesive methods. However, for extensive wear or widespread damage, full sheet replacement may be needed to keep it waterproof.

Question 4

Is torch‑on roofing felt the same as torch‑on mineral felt?

Accepted Answer

Yes. In UK flat‑roof terminology, the terms torch‑on mineral felt and torch‑on roofing felt generally describe the same system. Both refer to modified bitumen membranes installed using a propane torch and capped with a mineral surface.
