Baffle-vent for S-tile ridge

Abstract

An air vent for tiled roofs is installed for air exchange occurs through a slit near the roof apex. The vent has a plurality of layers of corrugated materials defining a plurality of airways for air exchange. In one embodiment, a baffle is attached to a vent member. In another embodiment, a plurality of vent members is attached to a top panel, which may be made from the corrugated material, optionally with a route exposing airways for additional air exchange. A membrane may be present on the embodiments to prevent ingress of water, particulates, and insects into the roof interior. A covering member and/or a layer of cementous material may be used to further prevent undesired ingress of water, particulates, or insects. If present, the covering member is adhered to a lower panel of one embodiment and disposed below the baffle in another embodiment.

1 . A vent assembly for effecting air exchange in a roof, comprising: 
 a vent member having a longitudinal axis and including at least one layer of a corrugated material, the corrugated material comprising a pair of first plies and at least one second ply disposed between the first plies to define a plurality of airways; and    a generally resilient baffle member attached to the vent member.    
     
     
         2 . The vent assembly of  claim 1 , in which the first plies are generally planar.  
     
     
         3 . The vent assembly of  claim 1 , in which said at least one second ply is generally convoluted.  
     
     
         4 . The vent assembly of  claim 1 , in which the at least one second ply is a plurality of cross walls extending transversely between the first plies.  
     
     
         5 . The vent assembly of  claim 4 , in which said plurality of cross walls extend generally perpendicularly between the first plies.  
     
     
         6 . The vent assembly of  claim 1 , in which the baffle member comprises a first section and a second section defined from the first section by a first bend and extending generally transversely from the first section.  
     
     
         7 . The vent assembly of  claim 6 , in which the baffle member second section extends away from the vent member.  
     
     
         8 . The vent assembly of  claim 6 , in which the baffle member further comprises a third section separated from the second section by a second bend.  
     
     
         9 . The vent assembly of  claim 6 , further comprising a covering member disposable beneath the baffle member second section and comprising an upper surface and upper and lower undulations extending from the upper surface.  
     
     
         10 . A vent assembly for effecting air exchange in a roof, comprising: 
 a top panel with a longitudinal axis and formed from a corrugated material defining a plurality of airways extending generally transversely to the longitudinal axis;    a pair of vent members attached to a lower surface of the top panel, each of said plurality of vent members comprising a plurality of panels made from said corrugated material;    a membrane attached to said top panel or said vent members so as to prevent ingress of moisture into an interior portion of said roof; and    an adhesive member attached to a lower surface of each of said pair of vent members and comprising a generally flexible substrate, an adhesive overlaying one surface of said substrate, and a release liner overlaying the adhesive.    
     
     
         11 . The vent assembly of  claim 10 , further comprising a covering member attached to each of said adhesive members.  
     
     
         12 . The vent assembly of  claim 10 , further comprising a covering member, said covering member comprising an upper surface and upper and lower undulations extending from the upper surface, said upper surface adhered to said adhesive member.  
     
     
         13 . The vent assembly of  claim 10 , in which said corrugated material comprises a pair of generally planar first plies and at least one second ply disposed between the first plies.  
     
     
         14 . The vent assembly of  claim 13 , in which said at least one second ply is generally convoluted.  
     
     
         15 . The vent assembly of  claim 13 , in which said at least one second ply is a plurality of cross walls extending generally transversely to said first plies.  
     
     
         16 . A method of ventilating a roof with a ridge, the roof overlain with tiles, and having a slot formed proximate said ridge, said slot fluidly communicating an interior with an exterior of said roof, a vent assembly of any of the preceding claims disposed so that air egressing said roof passes through said airways, the method comprising egressing air from the interior of said roof, through said airways in said vent assembly, to the exterior of said roof.  
     
     
         17 . The method of  claim 16 , in which a pair of slots straddling the ridge are present and in which egressing air from said roof interior passes through said vent assembly airways.  
     
     
         18 . The method of  claim 16 , in which said vent is at least partially disposed in said slots.  
     
     
         19 . The method of  claim 16 , in which said vent is disposed above said slots.  
     
     
         20 . The method of  claim 16 , in which said vent inhibits ingress of water, particulates, or insects into said roof interior.  
     
     
         21 . The method of  claim 19 , in which a covering member, a baffle, or a membrane inhibits said ingress.
