Low profile roof vent

Abstract

A low profile roof vent incorporates a base portion which includes a water collecting tray extending down from a peripheral flange and a water shield portion extending from the opening of the vent towards the base tray. The base tray leads to a forward edge of the vent allowing any water collecting in the base tray to flow out from the vent onto the roof surface. The vent further incorporates a vent cover coplanar with the peripheral flange of the base. This provides a vent which lies flush with the roof surface, improving the aesthetic appeal of the roof.

1 . A roof vent comprising a peripheral flange member, a base tray with a back wall and first and second side walls and a front edge said back wall and said side walls spaced from said flange member providing air paths and wherein said front edge is joined to a forward portion of said flange member;
 a water shield member having back and side walls extended from flanges of said flange member and spaced inwardly from said walls of said base tray providing an air path; and   a vent cover with an edge portion wherein said vent cover is coplanar with said peripheral flange and when a lower edge of said vent cover is spaced from said forward portion of said flange member providing a water path from said base tray out of said vent.   
     
     
         2 . A low profile roof vent comprising a base and a cover said base having a peripheral flange said peripheral flange having a top flange member, first and second side flange members, and a bottom flange member, said top, side and bottom flange members defining an opening;
 a base tray having a bottom and a back wall and two side walls and a forward edge, said forward edge integral with said bottom flange member said base tray supported from a bottom portion of said peripheral flange and spaced from said opening;   a water shield having a back wall and first and second side walls extended from edges of said opening towards said base tray said walls spaced inwardly of said walls of said base tray providing an air path from an inner side of said vent through said opening;   and wherein said cover is coplanar with said peripheral flange.   
     
     
         3 . The roof vent claimed in  claim 2  further comprising a brace member extending from said first side flange member to said second flange member said brace spaced from said forward flange member providing a water path. 
     
     
         4 . The roof vent claimed in  claim 2  wherein said cover includes a series of louvers defining openings in said cover. 
     
     
         5 . The roof vent claimed in  claim 2  wherein said base comprises two pieces bonded together, a first piece comprising said base tray wherein said base tray incorporates two corner posts extending to a ledge wherein said ledge is bonded to a bottom surface of said flange member and wherein said second piece is a water shield member formed integrally with said side and top flange members. 
     
     
         6 . The roof vent claimed in claimed in  claim 5  wherein said side flange members overlap said bottom flange member. 
     
     
         7 . The roof vent claimed in  claim 2  wherein said base tray is larger than said opening. 
     
     
         8 . A sloped roof having a roof vent as claimed in  claim 2  wherein said cover is coplanar with said roof surface.
