Typical exposure of 3-tab asphalt shingles?

• A. 3 inches
• B. 4 inches
• C. 5 inches
• D. 6 inches

Answer: (C)

Exposure is the portion of each shingle that is visible after installation. For 3-tab asphalt shingles, the standard practice is to have about 5 inches of each shingle exposed. This comes from the typical 12-inch-wide shingle and the way courses overlap: the upper course covers roughly 7 inches of the shingle below, leaving 5 inches visible. A smaller exposure, like 4 inches, would reduce the visible area and alter appearance and performance, while a larger exposure, such as 6 inches, isn’t typical for 3-tab shingles and can reduce overlap between courses, potentially affecting wind resistance. So, 5 inches is the standard exposure.
