That said, hereâs a list of the average roof lifespan per type of roofing material: 1  Asphalt Shingles â 15-30 years. 2  Wood Shakes â 30-50 years, when maintained. 3  Metal Roofs â 50+ years.  Tile Roofing â 50+ 1  years. Natural Stone â 50+, when maintained.  Synthetic Roofs â 30-50+, depending on material.
The average shingle roof, properly installed, should last anywhere from 20 years (for asphalt or torchdown roof), 30-40 years (wood shingled roof), 50+ years (metal roofs) and 100+ years (clay tile shingles). Your home has layers to help protect it from the environment and to effectively insulate the home.
