Common Questions

What’s the Standard Size for Rolls of Torch-On Roofing Felt?

Roofing felt, including torch-on felt generally comes in standard sizes of roughly 1x8m. This size offers the perfect balance of practicality and value for money, as a single roll of felt can adequately be used to complete common small projects such as a garden shed roof.

How Many Layers of Torch-On Felt Do You Need for a Flat Roof?

In general, you’ll need three layers to cover a flat roof with torch-on felt. This means that you’ll need triple the square footage of your roof area to complete the job, as well as accounting 10% or more for waste. The three layers include a vapour control layer, bitumen roofing felt, as well as a cap sheet. For smaller flat roofing projects such as garages or sheds, it may be possible to only use two layers rather than three.
