Ridge Cap
The protective seal along your roof peak — combining weather protection with ventilation.
Ridge cap is the material that seals the horizontal peak where two sloping roof planes meet at the top of your roof. On shingle roofs, these are specially designed thick shingles that wrap over the ridge. On tile roofs, dedicated ridge tiles are mortared or mechanically fastened in place. Ridge cap serves the dual purpose of weatherproofing the most exposed point of your roof and, when combined with a ridge vent, providing the exhaust pathway for your attic ventilation system.
Why It Matters
The ridge is the highest and most wind-exposed point on your roof. Ridge cap shingles or tiles take a beating from wind, UV radiation, and thermal cycling, and they are often the first roofing component to fail. Cracked, lifted, or missing ridge cap allows water directly into your attic at the worst possible location. When combined with a ridge vent, the ridge also serves as the primary exhaust for attic ventilation — making it essential for both waterproofing and climate control inside your home.
