Abstract
A ventilating cap for the ridge of a roof includes a pair of vent parts located on opposite sides of a vent opening cut along ridge board of the roof. A flashing holds an air permeable, moisture-repelling fabric against the outer edge of the vent parts, thereby preventing intrusion of snow and other moisture into the vent opening through the vent parts.
Claims14
A ventilating cap for a ridge of a roof, said roof having a pair of upwardly tapering sides tapering toward said ridge and a vent opening extending longitudinally along said ridge, said cap including a pair of vent parts, each of said vent parts being located on said roof along opposite sides of said vent opening and having an upper surface extending across said vent opening to interconnect said vent parts and inner and outer side edges extending from said upper surface to said roof, each of said vent parts further defining elongated vent passages extending transversely between said inner and outer side edges to provide a vent path from said vent opening to ambient atmosphere, and a flexible, air permeable, moisture repelling fabric covering said outer side edges and extending over said vent passages to resist penetration of moisture into said vent openings.
