Expert Verdict — Reviewed by the SuperArbor Pro Desk
Strip vents like the S-400 are a straightforward way to balance intake airflow along eaves or to vent small ridge runs where a continuous ridge vent is not practical. Calculate your required NFVA from attic square footage and code, then divide by 10 sq. in./ft. to get the lineal footage needed. Keep the black color in mind for visibility against lighter shingles.
Follow the manufacturer's installation instructions and local building code for attic ventilation; work safely on roofs with proper fall protection.
Order Cor-A-Vent S-400 black strip vent to add reliable intake or exhaust airflow to your roof.
