Molded roof flashing system

Abstract

A flashing strip for placement at an intersection between a wall and an adjacent roof against which a plurality of shingles are to be laid, the flashing strip comprising an elongated back panel from which a plurality of flashing tabs extend outward. The flashing tabs are disposed at an angle to the axis and in substantially parallel planes to one another. During use, the elongated back panel is disposed against and coupled to the wall at the intersection, and shingles are then placed along the flashing tabs during the roofing process. The flashing strip may also include a ledge and/or a decorative molding above the flashing tabs. The flashing strips may be placed end to end to form a continuous flashing strip that may be installed before the placement of siding or the like on the wall. The siding may be installed by positioning the siding against the ledge before or after placement of the shingles.

1 . A flashing strip for placement at an intersection between a wall and an adjacent roof against which a plurality of shingles are to be laid, the flashing strip comprising: 
 an elongated back panel having an axis of elongation, an outside surface, an inside surface, a leading edge, and a trailing edge having a thickness, a portion of the outside surface being disposed in a major plane, said back surface at said leading edge comprising an offset portion offset from the major plane in an amount at least equal to the thickness of the trailing edge,    a plurality of flashing tabs extending outward from the outside surface of said back panel, the flashing tabs being disposed at an acute angle to the axis, in substantially parallel planes to one another, and being adapted to receive at least one of said shingles adjacent thereto, and    such that the inside surface of the elongated back panel may be disposed against the wall and the plurality of shingles may be disposed along the plurality of flashing tabs.    
   
   
       2 . The flashing strip of  claim 1  for use with siding strips, the flashing strip further comprising an elongated ledge for placement of siding strips.  
   
   
       3 . The flashing strip of  claim 2  wherein the elongated ledge extends outward from the outside surface of the elongated back panel.  
   
   
       4 . The flashing strip of  claim 1  wherein the inside surface of the back panel is disposed in a first plane, and a flashing tab is disposed in a second plane, said first and second planes being disposed at an angle of less than 90° to one another.  
   
   
       5 . The flashing strip of  claim 1  wherein the back panel includes an upper edge and a lower edge, an entirety of the flashing tabs extending from the back panel between the upper and lower edges such that placement of the lower edge against the roof spaces at least a portion of said flashing tabs away from the roof.  
   
   
       6 . The flashing strip of  claim 1  further comprising a leading flashing tab disposed toward the leading edge, and wherein the offset portion does not extend below at least part of the leading flashing tab.  
   
   
       7 . The flashing strip of  claim 6  further comprising an elongated ledge, said elongated ledge not extending along at least part of the trailing edge.  
   
   
       8 . The flashing strip of  claim 1  wherein the trailing edge comprises a front surface and said leading edge has a thickness, the front surface at said trailing edge comprising an offset portion offset from a major plane in an amount at least equal to the thickness at the leading edge.  
   
   
       9 . The flashing strip of  claim 1  further comprising a spacer disposed near an end of the flashing strip, the spacer adapted to rest on a flashing tab of an adjacently disposed flashing strip to establish a preset spacing between flashing tabs of adjacently disposed flashing strips.  
   
   
       10 . The flashing strip of  claim 9  wherein the spacer extends below the offset portion in the same plane as the offset portion.  
   
   
       11 . The flashing strip of  claim 9  wherein the spacer is disposed near the leading edge of the flashing strip.  
   
   
       12 . A flashing strip for placement at an intersection between a wall and an adjacent roof against which a plurality of shingles are to be laid, the flashing strip comprising: 
 an elongated back panel having an axis of elongation, an outside surface, and an inside surface,    a plurality of flashing tabs extending outward from the outside surface of said back panel, the flashing tabs being disposed at an acute angle to the axis, in substantially parallel planes to one another, and being adapted to receive at least one of said shingles adjacent thereto, and    a spacer disposed near an end of the flashing strip, the spacer adapted to rest on a flashing tab of an adjacently disposed flashing strip to establish a preset spacing between flashing tabs of adjacently disposed flashing strips,    such that the inside surface of the elongated back panel may be disposed against the wall and the plurality of shingles may be disposed along the plurality of flashing tabs.    
   
   
       13 . The flashing strip of  claim 12  wherein the spacer is disposed such that a bottom edge of the spacer is substantially parallel with the flashing tabs.  
   
   
       14 . The flashing strip of  claim 12  wherein the spacer extends downward from a flashing tab.  
   
   
       15 . The flashing strip of  claim 12  wherein the spacer extends upward from a flashing tab.  
   
   
       16 . A flashing strip for placement at an intersection between a wall and an adjacent roof against which a plurality of shingles are to be laid, the flashing strip comprising: 
 an elongated back panel having an axis of elongation, an outside surface, an inside surface, a first portion disposed in a first plane, a second portion disposed in a second plane at an angle to the first plane to form an elongated edge for placement of siding strips, a third portion disposed in a third plane at an angle to the second plane,    a plurality of flashing tabs extending outward from the outside surface of said back panel, the flashing tabs being disposed at an acute angle to the axis, in substantially parallel planes to one another, and being adapted to receive at least one of said shingles adjacent thereto, and    such that the inside surface of the elongated back panel may be disposed against the wall and the plurality of shingles disposed along the plurality of flashing tabs.    
   
   
       17 . The flashing strip of  claim 16  wherein the flashing tabs extend outward from said third portion of the elongated back panel.  
   
   
       18 . The flashing strip of  claim 16  wherein the third portion has a width and forms a decorative molding.  
   
   
       19 . The flashing strip of  claim 16  further comprising a fourth portion disposed in a fourth plane at an angle to said third plane, and a fifth portion disposed in a fifth plane at an angle to said fourth plane, said flashing tabs extending outward from said fifth portion.  
   
   
       20 . The flashing strip of  claim 19  wherein said fifth and first planes are disposed in substantially the same plane.
