Which Wind Exposure category is characterized by rolling terrain and wooded areas?

• A. Exposure A
• B. Exposure B
• C. Exposure C
• D. Exposure D

Answer: (B)

The correct answer is that Wind Exposure B is characterized by rolling terrain and wooded areas. This classification reflects environments where natural features, such as forests, hills, and other forms of terrain, obstruct wind flow, reducing wind speed and turbulence. The presence of these features contributes to a more sheltered condition compared to other exposure categories. In contrast, Exposure A pertains to open terrain with scattered obstructions, while Exposure C is associated with dense urban areas where buildings create a different wind environment. Exposure D typically comprises flat, unobstructed areas that experience the full force of wind. Each of these categories plays a significant role in understanding how wind impacts roofing systems during design and evaluation processes.
