Second layer roofing drip edge with protruding edge

Abstract

Hereby is disclosed a second layer roofing drip edge with a protruding edge. The drip edge covers an existing drip edge and shingles at the eave and rake prior to the installation of the next roofing system. The protruding edge may be notched on one section and not the other section as they abut. The protruding edge bottom fold or bottom face of the drip edge may be fabricated with a groove or projection preventing capillary action of water across the plane and dropping behind the gutter.

What is claimed is: 
     
         1 . A drip edge comprising:
 a planar nail flange configured to be laid-up on a roof, the planar nail flange comprising a first edge configured to be located, following its installation, on a roofing surface and a second, edge configured to, following installation of the drip edge on the roofing surface, protrude off of the rake or eave of a roof, forming a nose;   a feature located in a bottom-facing portion of the nose, the feature being configured to encourage water flowing along the nose to detach therefrom,   wherein the feature is configured to be weather-exposed following installation of the drip edge.   
     
     
         2 . The drip edge of  claim 1  wherein said feature comprises a groove. 
     
     
         3 . The drip edge of  claim 1  wherein said feature comprises a projection. 
     
     
         4 . The drip edge of  claim 1  wherein said feature is configured to allow drip edges to interlock with one another, forming a continuous drip edge. 
     
     
         5 . The drip edge of  claim 4  wherein said features interlock by snapping the feature of one drip edge over the feature of another drip edge. 
     
     
         6 . The drip edge of  claim 1 , further comprising a series of divots positioned on said planar nail flange. 
     
     
         7 . The drip edge of  claim 6 , wherein said series of divots positioned on said planar nail flange are arranged in a line parallel to said first and second edges. 
     
     
         8 . The drip edge of  claim 7 , wherein said series of divots positioned on said planar nail flange are uniformly spaced. 
     
     
         9 . The drip edge of  claim 1 , further comprising a series of markings positioned on said planar nail flange. 
     
     
         10 . The drip edge of  claim 9 , wherein said series of markings positioned on said planar nail flange are arranged in a line parallel to said first and second edges. 
     
     
         11 . The drip edge of  claim 10 , wherein said series of markings positioned on said planar nail flange are uniformly spaced. 
     
     
         12 . The drip edge of  claim 11 , wherein said second, protruding edge comprises a closed hem. 
     
     
         13 . The drip edge of  claim 12 , wherein said drip edge comprises a notch configured to allow for joining of one section drip edge to another. 
     
     
         14 . The drip edge of  claim 1 , wherein said drip edge comprises a notch configured to allow for joining of one section drip edge to another. 
     
     
         15 . The drip edge of  claim 1 , wherein said second, protruding edge comprises a closed hem. 
     
     
         16 . The drip edge of  claim 15 , wherein the groove or projection is located in a bottom-facing portion of said closed hem. 
     
     
         17 . The drip edge of  claim 16 , wherein said groove or projection is aligned substantially parallel with said second protruding edge. 
     
     
         18 . The drip edge of  claim 1 , wherein the projection or groove is located in said substantially planar, flat bottom face. 
     
     
         19 . The drip edge of  claim 18  wherein said projection or groove is positioned adjacent said flat face and substantially parallel thereto. 
     
     
         20 . A method of waterproofing a building enveloped comprising:
 using the drip edge of  claim 1 :   aligning said drip edge with a roof such that the second, protruding edge is substantially parallel to a rake or eave of the roof and extending therefrom;   nailing the drip edge to the building envelope through the nail flange; and   applying an overlying course of roofing material on top of the drip edge.
