Off-ridge roof vent

Abstract

An off-ridge vent for a roof may comprise a longitudinally-extending main body having an arcuate lateral cross-sectional shape with two ends, a front flange extending from one lateral side of the main body, and a rear flange extending the other lateral side of the main body; two end caps, each end cap attached to and closing one of the ends of the main body, each end cap including a face portion which attaches to the main body and a side flange extending from the face portion; wherein, at least one of the end caps comprises a vented portion. The rear flange of the main body and the side flanges of the end caps may comprise return flanges that assist in redirecting any water that contacts the flange. The vent may overlay an aperture in the roof such that air may flow through the aperture and out the axial vent ends.

1 . An off-ridge roof vent, comprising:
 a longitudinally-extending main body having an arcuate lateral cross-sectional shape with two ends, a front flange extending from one lateral side of the main body, and a rear flange extending the other lateral side of the main body;   two end caps, each end cap attached to and closing one of the ends of the main body, each end cap including a face portion which attaches to the main body and a side flange extending from the face portion; wherein,   at least one of the end caps comprises a vented portion.   
   
   
       2 . The off-ridge vent of  claim 1 , wherein the main body comprises a continuously-curved cross-section. 
   
   
       3 . The off-ridge vent of  claim 1 , wherein the main body does not comprise a vented portion. 
   
   
       4 . The off-ridge vent of  claim 1 , wherein the end caps are mechanically fastened to the ends of the main body. 
   
   
       5 . The off-ridge vent of  claim 4 , wherein the end caps are fastened to the ends of the main by an interlocking hem. 
   
   
       6 . The off-ridge vent of  claim 1 , wherein the front flange and rear flange are substantially coplanar. 
   
   
       7 . The off-ridge vent of  claim 1 , wherein the front flange, rear flange, and both side flanges are substantially coplanar. 
   
   
       8 . The off-ridge vent of  claim 1 , wherein the rear flange further comprises a return flange, the return flange extending at an angle toward the main body. 
   
   
       9 . The off-ridge vent of  claim 8 , wherein the side flanges each comprise a return flange, the return flange extending at an angle toward the main body. 
   
   
       10 . The off-ridge vent of  claim 1 , wherein the side flanges each comprise a return flange, the return flange extending at an angle toward the main body. 
   
   
       11 . The off-ridge vent of  claim 1 , wherein the main body, front flange, and rear flange are monolithic. 
   
   
       12 . The off-ridge vent of  claim 1 , wherein at least one of the end caps includes an aperture therethrough, and wherein a vent insert is attached to the aperture. 
   
   
       13 . The off-ridge vent of  claim 11 , wherein the vent insert is rotatably attached to the end cap aperture. 
   
   
       14 . A roof assembly for use in high wind areas, comprising:
 a roof deck, the roof deck having an aperture therethrough;   at least one underlayment layer attached to a top of the roof deck;   a vent overlaying the roof deck aperture and attached to the roof deck, the vent comprising:
 a longitudinally-extending main body having two ends and an arcuate lateral cross-sectional shape, a front flange extending from one lateral side of the main body, and a rear flange extending the other lateral side of the main body; 
 two end caps, each end cap attached to one of the ends of the main body, each end cap including a face portion which attaches to the main body and a side flange extending from the face portion; wherein at least one of the end caps comprises a vented portion. 
   
   
   
       15 . The roof assembly of  claim 14 , wherein the front flange and rear flange of the main body are located under a portion of the underlayment layer. 
   
   
       16 . The roof assembly of  claim 14 , wherein the front flange and rear flange of the main body are located on a top surface of the underlayment layer. 
   
   
       17 . The roof assembly of  claim 14 , wherein a portion of at least one roof tile is installed over at least one of the front flange and rear flange. 
   
   
       18 . The roof assembly of  claim 14 , wherein the vent is located on the roof assembly at a location other than the ridge of the roof. 
   
   
       19 . The roof assembly of  claim 14 , wherein the rear flange of the vent further comprises a return flange, the return flange extending at an angle toward the main body. 
   
   
       20 . A method of venting a tiled roof in a high wind area, comprising the steps of:
 providing a roof deck having an outer surface and an aperture therethrough;   providing a vent having a longitudinally-extending main body with an arcuate lateral cross-sectional shape, front and rear lateral flanges, and two axial vented ends, the axial vented ends comprising the sole vented portion of the vent;   optionally providing at least one underlayment layer attached to an outer surface of the roof deck;   attaching the vent to the roof deck such that the vent main body overlays the aperture in the roof deck; and,   attaching a tile to the roof such that a portion of the tile overlaps the rear lateral flange.
