Which way is the ridge applied?

• A. Toward the weather side
• B. Parallel to the weather side
• C. Away from the weather side
• D. Along the ridge line

Answer: (C)

Focus on directing water away from the ridge joint. The weather side is the side facing wind and rain. When the ridge cap is applied away from that side, the cap’s overlap and edge are positioned to shed precipitation down the roof surfaces rather than driving it into the ridge seam. This orientation helps keep the ridge line drier, improves sealing against leaks, and reduces wind-driven water infiltration at the ridge. Using other directions would not optimize runoff away from the joint, which is why this option is preferred.
