Which roof type consists of a series of ridges that resemble the teeth of a saw?

• A. Sawtooth
• B. Gambrel
• C. Arch
• D. Monitor

Answer: (A)

Recognizing roof profiles by their silhouette helps you identify roof types quickly. A roof with a repeating series of ridges that look like the teeth of a saw is called a sawtooth roof. The profile creates a jagged line along the building length because each module combines a pitched edge with a vertical or near-vertical face. This design is often used in industrial buildings to admit daylight through the vertical faces while the angled portions shed water on the opposite side. In contrast, a gambrel roof shows two slopes on each side like a barn, an arch roof has a curved, sweeping profile, and a monitor roof features a raised central section with clerestory windows.
