That's somewhat optimistic, according to the Metal Roofing Alliance, which says a metal roof lasts 40 to 60 years while the average life span of an asphalt roof is 12 to 20 years.. Your shingles might defy predictions one way or the other.
1 Wood shingles and shakes -- Wood roofing has a target lifetime of 30 years, but it can last much longer under moderate weather conditions.  Metal -- The International Association of Certified Home Inspectors projects metal roofing to last between 40 to 80 years. The Metal Roofing Alliance gives a life expectancy of at least 40 to 60 years.
