Fit and Compatibility:
Designed for asphalt shingle roofs and installs beneath the cap shingles; use with balanced intake ventilation such as eave or soffit vents for best performance. Cor-A-Vent also offers a 9 in. wide Revolution version (REV-9) for narrower ridges.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the 12 sq-in per foot of exhaust NFVA with equal or greater intake NFVA at the eaves, or the ridge vent will underperform regardless of quality. Because Revolution is power nailable and resists compression, it holds its vent channel under cap shingles where foam competitors can crush. The 9 in. REV-9 width suits narrower ridges or hips where the 11 in. cut-back is excessive.
Follow the manufacturer's installation instructions and local building codes for attic ventilation, and use fall protection when working on the roof.
Order the Cor-A-Vent Revolution rolled ridge vent for high-flow, eco-smart attic exhaust.
