Roof vent

Abstract

A roof vent is provided that exhibits simplicity of construction, ease of installation, durability, and effectiveness. The roof vent may be made of metal. In one embodiment, components of the roof vent include Z-shaped support members, a vent cap that attaches to the Z-shaped members, and end caps that attach to the Z-shaped members. In one embodiment, the vent cap attaches to and extends between first and second Z-shaped members, the vent cap having edge flanges that extends inwardly at an acute angle relative to the vent cap and project downwardly so as to deflect downward wind and rain. In another embodiment, at least one adjustable closure is coupled to a Z-shaped member for reducing venting action and protecting against penetration of wind, rain, etc.

         1 . A roof vent comprising:
 first and second Z-shaped members, each Z-shaped member comprising a top portion, a bottom portion and a middle portion joining the top portion and the bottom portion, wherein perforations are formed in at least part of the middle portion;   a vent cap attached to and extending between the first and second Z-shaped members, the vent cap comprising edge flanges that extend inwardly at an acute angle relative to the vent cap and project downwardly so as to deflect downward wind and rain; and   at least one end cap ajoining the Z-shaped members and the vent cap for enclosing a space above the roof.   
     
     
         2 . The apparatus of  claim 1 , wherein perforations are formed in at least part of the bottom portion of the Z-shaped members. 
     
     
         3 . The apparatus of  claim 1 , wherein the bottom portion of the Z-shaped members comprises an edge lip that extends upwardly toward the top portion of the Z-shaped members. 
     
     
         4 . The apparatus of  claim 1 , wherein the roof vent is a roof ridge vent shaped so as to follow contours of a roof ridge. 
     
     
         5 . The apparatus of  claim 1 , wherein the vent cap comprising an apex, a first portion extending downwardly from the apex in one direction, and a second portion extending downwardly from the apex in an opposite direction. 
     
     
         6 . The apparatus of  claim 1 , wherein the end cap comprising a chevron-shaped closure portion, a first flange portion configured to underlie the vent cap, and a second flange portion configured to underlie a final roofing material. 
     
     
         7 . The apparatus of  claim 1 , wherein at least one of the vent cap and the end cap comprises an applied finished that simulates roofing material. 
     
     
         8 . The apparatus of  claim 1 , comprising at least one adjustable closure coupled to a Z-shaped member for reducing venting action and protecting against penetration of wind and rain. 
     
     
         9 . The apparatus of  claim 8 , wherein the adjustable closure is configured to at least partially close at least some of said perforations. 
     
     
         10 . The apparatus of  claim 8 , wherein the closure member comprises perforations, and wherein the closure member and the Z-shaped member are coupled such that a degree of registration of perforations of the closure member and the Z-shaped member is adjustable. 
     
     
         11 . A roof vent comprising:
 first and second Z-shaped members, each Z-shaped member comprising a top portion, a bottom portion and a middle portion joining the top portion and the bottom portion, wherein perforations are formed in at least part of the middle portion;   a vent cap attached to and extending between the first and second Z-shaped members;   at least one end cap adjoining the Z-shaped members and the vent cap for enclosing a space above the roof ridge; and   at least one adjustable closure coupled to a Z-shaped member for reducing venting action and protecting against penetration of wind and rain.   
     
     
         12 . The apparatus of  claim 11 , wherein the closure member is configured to at least partially close at least some of said perforations. 
     
     
         13 . The apparatus of  claim 12 , wherein the closure member comprises perforations, and wherein the closure member and the Z-shaped member are coupled such that a degree of registration of perforations of the closure member and the Z-shaped member is adjustable. 
     
     
         14 . The apparatus of  claim 11 , wherein the vent cap comprises edge flanges that extend inwardly at an acute angle relative to the vent cap and project downwardly from the vent cap so as to deflect downward wind and rain. 
     
     
         15 . The apparatus of  claim 11 , wherein perforations are formed in at least part of the bottom portion of the Z-shaped member. 
     
     
         16 . The apparatus of  claim 11 , wherein the bottom portion of the Z-shaped member comprises an edge lip that extends upwardly toward the top portion. 
     
     
         17 . The apparatus of  claim 11 , wherein the roof vent is a roof ridge vent shaped so as to follow contours of a roof ridge. 
     
     
         18 . The apparatus of  claim 11 , wherein the vent cap comprising an apex, a first portion extending downwardly from the apex in one direction, and a second portion extending downwardly from the apex in an opposite direction. 
     
     
         19 . The apparatus of  claim 11 , wherein the end cap comprising a chevron-shaped closure portion, a first flange portion configured to underlie the vent cap, and a second flange portion configured to underlie a final roofing material. 
     
     
         20 . The apparatus of  claim 11 , wherein at least one of the vent cap and the end cap comprises an applied finished that simulates roofing material. 
     
     
         21 . The apparatus of  claim 1 , wherein the vent cap and the Z-shaped members are configured such that the edge flanges of the vent cap engage the top portions of the Z-shaped members, with the top portions of the Z-shaped members in a protruding position.
