Which style of roof involves rafters or trusses that run from the ridge line to the top of the outer walls at eaves level?

• A. Butterfly
• B. Pitched
• C. Arched
• D. Flat

Answer: (B)

The main idea is how roof framing members connect the ridge to the walls. In a pitched roof, rafters or trusses run from the ridge line down to the tops of the exterior walls at the eaves, creating a sloped surface. This triangle-shaped cross-section is the classic look of a pitched roof and is built to shed water and snow efficiently. A butterfly roof has two sections that slope toward a central valley, not from ridge to eaves. An arched roof uses curved framing to form a rounded profile rather than straight-angled rafters. A flat roof is nearly level with little slope. So the described configuration clearly matches a pitched roof.
