Your roof's expected life is dependant on the type of system you have, the maintenance it has received, and the external elements it has endured. However, generally speaking built up roofing can be expected to last 12 to 20 years; shingles 15 to 20 years; wood shake or shingles, 10 to 40 years; clay/concrete tile, in excess of 20 years; metal roofing, 15 to 40 years; and stated before Slate at 30 to 100 years. Each manufacturer offers additional warranty details. Your individual experience may vary from these national averages.
