4' shingle-over ridge vent is a low profile external baffle vent that creates a clean, uncluttered roofline. It installs on the peak of the roof, allowing exhaust ventilation along the entire ridge. An external baffle creates low pressure over the vent openings to pull air from the attic and deflects wind and weather over the vent to help protect the attic from rain and snow infiltration. The Attic-Aire has an internal weather filter which provides a more complete barrier to help protect the attic from wind, rain, snow, dust, and insects. The vent has pre-printed slot guides for truss or ridge pole construction and pre-drilled nailing holes designed to assure proper nailing for easy installation. The vent is pre-formed to a 4/12 pitch and fits a 3/12 to 16/12 roof pitch. Provides 18" sq. in. of net free area per linear foot. Comparable to the Shingle Vent II Miami-Dade County approved. Lifetime limited warranty.
