Roof pipe flashing with side air attic vent

Abstract

A roof pipe flashing with a rectangular shaped side air attic vent attached to a partial boot with a frusto-conical wall and a flat base for exhausting air from an attic into the outer atmosphere during warm or hot seasons in order to help reduce the internal house temperature during these seasons.

What is claimed is: 
     
         1 . A roof pipe flashing for a shingled pitched roof of a building for providing the out-flow or exhaust of attic air to the atmosphere comprising a boot having a substantially frusto-conical wall, said boot having a semi-closed top end and a semi-closed bottom end with a roof vent pipe passing through both said semi-closed bottom end and said semi-closed top end, said semi-closed bottom end being larger than said semi-closed top end, said semi-closed top end of said boot having an opening such as to provide a water tight frictional engagement with said roof vent pipe, said semi-closed bottom end having a substantially rectangular, elongated extension with three walls, a top wall and a pair of oppositely spaced walls connected to said top wall, said top wall and each of said oppositely spaced walls having an end connected near said semi-closed bottom end of said frusto-conical wall, and said boot and said elongated extension are supported on a substantially rectangular flat base such that said substantially rectangular, elongated extension provides an open elongated attic air passageway from said boot to said atmosphere. 
     
     
         2 . A roof pipe flashing of  claim 1  wherein said boot, said substantially rectangular, elongated extension and said rectangular flat base form a monolithic structure. 
     
     
         3 . A roof pipe flashing of  claim 1  wherein said substantially rectangular, elongated extension has a free end with a front edge not connected to said boot and said substantially rectangular flat support base has a front edge, said front edge of said elongated extension being in vertical alignment with said front edge of said flat support base. 
     
     
         4 . A roof pipe flashing of  claim 1  wherein said substantially rectangular elongated extension has an open front end with a front filter attached thereto and said front filter has plural openings therein with said plural openings selected from the group of circular openings, spaced slats and square openings. 
     
     
         5 . A roof pipe flashing of  claim 4  wherein some of said circular openings extend nearly down to said flat base but are only partially contiguous with said flat base in order to prevent rainwater from accumulating within said elongated extension. 
     
     
         6 . A roof pipe flashing of  claim 4  wherein some of said square openings extend nearly down to said flat base but are only partially contiguous with said flat base in order to prevent rainwater from accumulating within said elongated extension. 
     
     
         7 . A roof pipe flashing of  claim 4  wherein the bottom ends of said spaced slats extend nearly down to said flat base but are not contiguous with said flat base in order to prevent rainwater from accumulating within said elongated extension. 
     
     
         8 . A roof pipe flashing of  claim 4  wherein said front filter has an air mesh filter secured behind and in abutment with said front filter. 
     
     
         9 . A roof pipe flashing of  claim 1  wherein said boot, said elongated extension and said flat base are made from an elastomeric material. 
     
     
         10 . A roof pipe flashing of  claim 1  wherein said boot, said elongated extension and said flat base are made from metallic material. 
     
     
         11 . A roof pipe flashing of  claim 1  wherein said substantially frusto-conical wall has a short right-angle extension at said semi-closed bottom end of said substantially frusto-conical wall and adjacent said substantially rectangular, elongated extension. 
     
     
         12 . At least one roof pipe flashing of  claim 1  in combination with a pitched shingled roof having a gutter and an apex ridge, one of said roof pipe flashings being secured near said gutter of said roof and another of said roof pipe flashings being secured near said apex ridge in order to increase the out-flow of attic air to the atmosphere. 
     
     
         13 . The roof pipe flashing of  claim 12  wherein there are two spaced roof pipe flashings near said gutter and one roof pipe flashing near said apex ridge.
