The life span of your roof depends upon quality of content, several factors; form of roofing, and contact with severe weather elements one of the top. With regular weathering facets and regular maintenance, a roof can last anywhere from 10 a century. Typical roofing material including built up roofing usually lasts metal roofing 15 40 years, 1-2 20 years, wood move or shingles 1-0 40 years, road shingles 15 20 years, and specialty material like stone up to 100 years under good conditions.
