Roofing shingle

Abstract

A roofing shingle has a folding nail-down or securing strip added to the edge of the shingle that is placed on the lower or down edge of the shingle. This folding nail-down strip is attached to the roof and then the shingle is folded up over the stip. After a row of shingles have been secured across the roof, then a second (and additional rows thereafter) are placed on the top edge of the first row. The folding nail-down strip is attached to the roof over the top edge of the first row, and the shingle is then folded up and over covering the attachment strip. Rows are similarly added until the roof is completely shingled.

1 . A roofing shingle, comprising: 
 a shingle having a main body of the shingle;    a nail down strip, and    a flexible member of the shingle attaching the nail down strip to the main body of the shingle.    
   
   
       2 . The roofing shingle according to  claim 1 , where in the nail down strip is an integral part of the shingle, separated from the main body by a reduced thickness area.  
   
   
       3 . The roofing shingle according to  claim 1 , wherein the nail down strip is a separate member attached to the mail body by a flexible material.  
   
   
       4 . The roofing shingle according to  claim 2  wherein the flexible material includes, but not limited, to one of plastic, mesh screen wire, and a glass fiber reenforced material.  
   
   
       5 . The roofing shingle according to  claim 1 , wherein the shingle includes a top side having a granular coating, and an opposite side having an asphalt coating.  
   
   
       6 . A roofing shingle including: 
 a main body of the shingle and a nail-down strip flexible attached to the main body of the shingle.    
   
   
       7 . The roofing shingle according to  claim 6 , where in the nail down strip is an integral part of the shingle, separated from the main body by a reduced thickness area.  
   
   
       8 . The roofing shingle according to  claim 6 , wherein the nail down strip is a separate member attached to the main body by a flexible material.  
   
   
       9 . The roofing shingle according to  claim 8 , wherein the flexible material includes, but not limited, to one of plastic, mesh screen wire, and a glass fiber reenforced material.  
   
   
       10 . The roofing shingle according to  claim 6 , wherein the shingle includes a top side having a granular coating, and an opposite side having an asphalt coating.  
   
   
       11 . The roofing shingle according to  claim 6 , wherein the nail-down strip is on the lower edge of the shingle as it is mounted on a roof.  
   
   
       12 . A method of attaching a shingle to a roof, comprising the steps of: 
 placing a single with a nail-down strip on one edge of the shingle on the roof;    nailing down the nail-down strip;    folding the shingle upward over the nail down strip so that there is an upper edge of the single;    continuing securing a row of singles side by side on the roof;    starting additional rows of shingles, securing the nail-down strip of each shingle over at least one previous row of shingles, and folding the shingle of each additional row upward over the nail-down strip; and    continuing applying shingles until the roof is covered.    
   
   
       13 . The method according to  claim 12 , wherein when the nail-down strip is first attached to the roof, another opposite edge of the shingle is extending in a downward direction of the roof until the shingle is folded upward over the nail down strip.  
   
   
       14 . The method according to  claim 12 , wherein the upward edge of each shingle in a row is secured by the nail-down strip of a subsequent row of shingles placed above and adjacent to the previous row of shingles.  
   
   
       15 . The method according to  claim 12 , wherein each shingle is nailed down to the roof with three rows of nails.  
   
   
       16 . The method according to  claim 15 , where each row of nails, after the first row of nails, in a shingle is from the next two rows of shingles above the shingle with the first row of nails.
