In roofing terminology, what is the measured amount of roof surface exposed to weather after installation called, usually expressed in inches?

• A. Downspout
• B. Eaves
• C. Exposure
• D. Drip edge

Answer: (C)

Exposure is the term for how much of each shingle is left visible after installation. That visible portion faces the weather, so it's measured in inches to standardize installation. The amount chosen affects water runoff, wind resistance, and overall look, and it varies by shingle type and manufacturer. Downspout, Eaves, and Drip edge refer to other roof or gutter components—downspouts carry water away from the roof, eaves are the roof edge, and a drip edge is a metal strip that directs water off the roof. Thus, exposure is the correct term for the measured surface exposed to weather.
