What Is a Ridge Cap? The ridge cap is where the two sides of your roof meet at the top of your home. It's essentially a large seam and it's a vulnerable part of your roof that is susceptible to leaks and damage.

Cap sheet roofing is a particular method that allows our team of roofing professionals to install a water-tight surface on low slope roofing. This is commonly used on modified bitumen roofing and built-up roofing, two very common commercial applications.

A roof ridge cap is an essential component of the roofing system that covers the peak or ridge of the roof, protecting this vulnerable area. It prevents water, debris, and pests from entering the ridge line, extending the roof's lifespan.

Composition: Cap sheet is typically made from modified bitumen, which is asphalt mixed with rubber or plastic modifiers. This gives it flexibility, durability, and resistance to weathering. Function: Cap sheet is the topmost layer of a multi-layer built-up roofing (BUR) system or a modified bitumen roofing system.
