Asphalt shingles top more than 80 percent of American houses. Figure about 20 years from three-tab, about 30 from architectural and 40 to 80 from metal. A typical California home built around 1994 would already be on its second roof if the first was three-tab, and close to it with architectural. Our free inspection shows which side of that line you are on.
