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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) Ventilating cap as claimed in claim 1, wherein said fabric is supported by a longitudinally extending flashing members extending along each of said outer side edges. ### Claim 3 (depends on 2) Ventilating cap as claimed in claim 2, wherein each of said flashing members are secured to a corresponding vent part. ### Claim 4 (depends on 3) Ventilating cap as claimed in claim 3, wherein one of more fasteners extend through the flashing members, the flexible fabric supported by the flashing members, and into the corresponding outer side edge to thereby secure said flashing members and the fabric supported thereby to said cap. ### Claim 5 (depends on 2) Ventilating cap as claimed in claim 2, wherein each of said flashing members includes a pair of side members forming an angle therebetween, one of said side members extending along the corresponding outer side edge of the cap, the other side member of each flashing member extending along the roof. ### Claim 6 (depends on 5) Ventilating cap as claimed in claim 5, wherein fasteners extend through said other side members to secure said flashing members to the roof, said flashing members being unattached to said vent parts. ### Claim 7 (depends on 5) Ventilating cap as claimed in claim 5, wherein fasteners extend through the one side members, said fabric, and into said vent parts to secure said flashing members to said vent parts. ### Claim 8 (depends on 2) Ventilating cap as claimed in claim 2, wherein said flashing member is perforated. ### Claim 9 (depends on 2) Ventilating cap as claimed in claim 2, wherein said flashing member is made of woven wire fabric. ### Claim 10 (depends on 9) Ventilating cap as claimed in claim 9, wherein each of said flashing members includes a pair of side members forming an angle therebetween, one of said side members extending along the corresponding outer side edge of the cap, the other side member of each flashing member extending along the roof, said fabric including a portion extending between said roof and the other side member. ### Claim 11 (depends on 9) Ventilating cap as claimed in claim 9, wherein said flashing member includes a turned over portion defining a pocket retaining said fabric on said flashing member. ### Claim 12 (depends on 2) Ventilating cap as claimed in claim 2, wherein said flashing member includes a turned over portion defining a pocket retaining said fabric on said flashing member. ### Claim 13 (depends on 2) Ventilating cap as claimed in claim 2, wherein a portion of said fabric extends from said flashing member and engages said roof. ### Claim 14 (depends on 2) Ventilating cap as claimed in claim 2, wherein said fabric is a nonwoven, spunbonded fabric consisting of randomly arranged nonwoven fibers.
