Felt Roofing

The main advantage of high performance felt roofing is its life span with many projects lasting way over its life expectancy. The high performance felt roof consists of three layers of sheet felt materials that form a dense, voidless and impermeable barrier. The high performance felt roof system is built up of multiple layers of torch-on bitumen felts that are pre coated with bitumen. The 3 layer system usually consists of a perforated underlay, a 2mm underlay layer, then a 4-5mm mineral finish.
