What Is Felt Roofing?

Felt roofing is largely made up of modified bitumen combined with either fibreglass or polyester. Felt roofing often consists of several different layers of material that form together and are sealed at the edges, resulting in a tight and durable bond between your property and the outside elements.
There are several methods of applying a felt roof to a building, but the more common technique in modern times is to use a blowtorch to partially melt one side of the felt until it is sticky. This side is then stuck down.
