Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose the 8-1/2 in. width for typical hip applications where the vent must follow diagonal hips and sit low on the roofline. Calculate total NFVA needed for the attic space, then divide between intake and exhaust—V-300E at 13.5 sq-in/ft. makes it easy to figure linear footage. Snap a straight line before cutting the sheathing slot and keep slot width consistent so the vent seats evenly.
Cutting roof sheathing and working on hips and ridges carries fall hazards—use proper fall protection, and follow roof covering manufacturer and local code requirements for ventilation and installation.
Order Cor-A-Vent V-300E 8-1/2 in. hip and ridge vent for snow-safe, low-profile attic exhaust.
