Why It Matters

The ridge is exposed to wind and weather. Proper ridge cap helps protect the roof peak and complete the shingle system.

Common Problems

Common problems include missing ridge caps, cracked caps, incorrect fastening, poor alignment, and ridge cap installed over ventilation incorrectly.

Building Codes & Industry Standards

Ridge cap should follow roof covering and ventilation manufacturer instructions, especially when installed over ridge ventilation.
