GAF Cobra Ridge Runner 11.5 in. x 30 ft. Black Filtered Plastic Roll Ridge Vent

Balanced attic ventilation means an equal amount of air entering and exiting it. The amount of exhaust ventilation must never exceed the amount of intake ventilation at the soffits or eaves. GAF recommends a minimum of 1 sq. ft. of net free ventilation for every 300 sq. ft. of attic floor space. Always consult local building codes for specific ventilation requirements.
