3-tab asphalt roofing should be replaced approximately every __ years.

Answer 30

3-tab asphalt roofing can have 20, 25, or 30 ratings. Wind and other weather conditions will determine the actual life expectancy of the shingle. Architectural shingles are also made of asphalt but are rated for higher wind exposures and are available in 30, 40, and 50-year ratings.
