Beaded step flashing

Abstract

A step flashing piece includes a bottom surface and a side surface. A raised bead is positioned in the surfaces generally parallel to the bend between the bottom and side surfaces.

The invention claimed is: 
     
         1 . A step flashing piece, comprising:
 a bottom surface and a side surface with a bend at the intersection of said bottom and side surfaces;   a raised bead positioned on said bottom surface; and   a raised bead positioned on said side surface.   
     
     
         2 . The step flashing piece of  claim 1 , wherein said raised beads are positioned generally parallel to said bend. 
     
     
         3 . The step flashing piece of  claim 1 , wherein said raised bead on said bottom surface and said raised bead on said side surface are the same distance away from said bend. 
     
     
         4 . The step flashing piece of  claim 1 , wherein said bottom surface and said side surface are perpendicular. 
     
     
         5 . The step flashing piece of  claim 1 , wherein said raised beads extend above the respective bottom and side surfaces by 0.01 to 0.04 inches. 
     
     
         6 . The step flashing piece of  claim 5 , wherein said raised beads extend above the respective bottom and side surfaces by 0.02 inches. 
     
     
         7 . The step flashing of  claim 1 , wherein said raised beads are positioned about 2 inches from said bend. 
     
     
         8 . The step flashing of  claim 7 , wherein said bottom and side surfaces are about 4 inches wide. 
     
     
         9 . A beaded step flashing piece, comprising:
 a bottom surface and a side surface with a bend at the intersection of said bottom and side surfaces; and   a raised bead positioned on said bottom surface generally parallel to said bend.   
     
     
         10 . The beaded step flashing piece of  claim 9 , wherein said bottom surface and said side surface are perpendicular. 
     
     
         11 . The beaded step flashing piece of  claim 9 , wherein said raised bead extends above the bottom surface by 0.01 to 0.04 inches. 
     
     
         12 . The beaded step flashing piece of  claim 11 , wherein said raised bead extends above the bottom surface by 0.02 inches. 
     
     
         13 . The beaded step flashing of  claim 9 , wherein said raised bead is positioned about 2 inches from said bend. 
     
     
         14 . The beaded step flashing of  claim 13 , wherein said bottom and side surfaces are about 4 inches wide. 
     
     
         15 . A step flashing piece, comprising:
 a bottom surface and a side surface with a bend at the intersection of said bottom and side surfaces;   a raised bead positioned on said bottom surface;   a raised bead positioned on said side surface; and   wherein said raised beads are positioned generally parallel to said bend.   
     
     
         16 . The step flashing piece of  claim 15 , wherein said raised bead on said bottom surface and said raised bead on said side surface are the same distance away from said bend. 
     
     
         17 . The step flashing piece of  claim 15 , wherein said bottom surface and said side surface are perpendicular. 
     
     
         18 . The step flashing piece of  claim 15 , wherein said raised beads extend above the respective bottom and side surfaces by 0.02 inches. 
     
     
         19 . The step flashing of  claim 15 , wherein said raised beads are positioned about 2 inches from said bend. 
     
     
         20 . The step flashing of  claim 19 , wherein said bottom and side surfaces are about 4 inches wide.
