Whether you decide to go for two or three layer torch down roofing will make a difference to your new roof's life. A three-layer roofing torch down project will include a base, smooth torch down and granule surface torch down, and should last for about 20 years. Two-layer torchdown roofing, with a base and one torch down layer, should have a life span ranging from 10 to 15 years. Regardless of whether you want your torchdown roofing to have two or three layers, you will have to use a base sheet.
