Torch down roofing is similar to gravel and tar roofs, consisting of fiberglass and polyester layers with added bitumen added to the traditional tar and gravel layer system. The extra sheets are placed in overlap areas during installation using a flame torch that melts the asphalt together with the seams. Some people refer to torch down roofing as modified bitumen, though there are differences in the two. Torch down roofing is strong and resistant to rain and snow. The life expectancy of 15-years is great considering the low initial purchase costs. The attractiveness of this roof material is a plus. The tar roof doesn’t offer the same type of beauty.
