Hip vent
A vent is disclosed for use in ventilating attic spaces beneath a hip roof. The vent is configured to be installed along a hip of the roof overlying and covering a ventilation slot. The vent includes an elongated laterally flexible top panel from which baffle arrays depend. The baffle arrays include a plurality of curved vanes that arc away from the slot. The vanes are configured to redirect wind-blown rain and snow away from the slot and block the migration of rain and snow through the vent. Filler strips can be attached beneath the edge portions of the vent. The filler strips conform to underlying shingles when the vent is installed to fill gaps that might be formed between the vent and the shingles. A weather filter can be positioned over some of the baffle arrays to allow attic air to pass but prevent ingress of blown snowflakes and raindrops.
1. A roof, comprising:
a hip or ridge having a slot formed therealong;
at least one vent configured to be installed along the slot and comprising:
a top panel including a central portion having an upper surface, a lower surface, and side edges;
a plurality of baffle arrays positioned along the lower surface of the top panel, each of the baffle arrays comprising a plurality of rows of spaced vanes;
wherein the baffle arrays comprise an outer region of baffle arrays positioned between the central portion of the top panel and each side edge of the top panel, and an inner region of baffle arrays positioned between the central portion of the top panel and each outer region of baffle arrays;
an outermost and lowermost vane of each baffle array has an arcuate portion that is oriented substantially transverse to an orientation of the vanes and a straight portion that extends from an inner end of the arcuate portion to connect integrally to a barrier wall of a plurality of barrier walls; and
wherein a plurality of second ends of at least some of the vanes located nearer an adjacent one of the side edges are arranged such that a transverse axis from the adjacent one of the side edges passing through each of the plurality of second ends also passes through first ends of adjacent vanes of an adjacent row of vanes such that water, snow, debris, or a combination thereof, encountering the vanes is redirected away from the slot formed along the ridge or hip of the roof and toward the side edges of the top panel.
2. The roof of claim 1 , wherein the inner regions of baffle arrays and the outer regions of baffle arrays are separated by a longitudinally extending gap.
3. The roof of claim 2 , further comprising an air permeable weather filter received within the longitudinally extending gap.
4. The roof of claim 1 , further comprising the plurality of barrier walls spaced along the lower surface of the top panel and extending between the side edges of the top panel and the central portion of the top panel; wherein one or more of the baffle arrays are separated by at least one barrier wall.
5. The roof of claim 1 , further comprising a filler strip positioned along at least some of the outer regions of baffle arrays adjacent each of the side edges of the top panel; wherein the filler strip is configured to conform to surfaces of adjacent shingles when the vent is installed on the roof.
6. The roof of claim 5 , wherein the filler strip comprises a plurality of polymer strands or a foam material.
7. The roof of claim 1 , wherein at least some of the vanes of at least one of the baffle arrays comprise independent structures not connected to another structure depending from the lower surface of the top panel.
