A two-layer system is made up of one base layer and one torch down layer. Three-layer systems have a base, a smooth torch down layer and a torch down layer with a granular surface. Two-layer systems tend to last approximately 15 years, while three-layer torch down roofing can last 20 years or longer.Jan 12, 2017
