Asphalt shingles are on more than 80 percent of American homes. Three-tab shingles usually run about 20 years and architectural shingles about 30, with metal lasting 40 to 80. A house built in the 1980s that is still on its first roof has outlived both kinds of shingle, and even a 1990s roof is now at the point where a free inspection tells you more than the view from the driveway.
