High profile composition shingles for roofs

Abstract

A high profile shingle for roofs includes a weather layer of composition material and a plurality of members of composition material arranged under said weather layer which are of varying lengths and arranged to cause the butt end of the shingle to be substantially thicker than the weather layer. In one embodiment, the members under the weather layer are a series of spaced, tapered strips arranged with their thick ends toward one end of the shingle and having an additional end strip abutted against the thick ends. Another embodiment uses a series of underlayers of the same width as the weather layer but of lengths varying from approximately one-half down to about one-eighth the length of the weather layer. A third embodiment uses a base layer of substantially greater width than the weather layer, a series of layers of progressively shorter lengths below the weather layer with the ends of the layers in registry at the butt end of the shingle with cut-out sections. A fourth embodiment comprises a weather layer and a plurality of underlayers of different lengths and the same width as the weather layer. The underlayers have one end aligned, their surfaces all bonded to its adjacent layer and fastened by staples with the outermost longest underlayment layer bonded to the underside of the weather layer. One edge of the weather layer and the common edges of the underlayment layers constituting the butt of the shingle.

1 . A high profile composition shingle for roofs comprising a weather layer of a composition material having a granulated surface: 
 a plurality of members of composition material positioned under said weather layer, said members being of varying lengths and arranged such that the butt end of said shingle is substantially thicker than said weather layer;    said layers below the weather layer being stapled together at the butt end region of said shingle.    
   
   
       2 . A high profile composition shingle as claimed in  claim 1  wherein said weather layer includes cut-outs extending from its outside edges over a substantial portion of its width.  
   
   
       3 . A high profile composition shingle as claimed in  claim 1  wherein said members of composition material below said weather layer are tapered from the butt end of different lengths.  
   
   
       4 . A high profile composition shingle as claimed in  claim 3  wherein a plurality of said layers of composition material have internal cut-out areas to provide internal recesses below said weather layers.  
   
   
       5 . A high profile composition shingle as claimed in  claim 3  wherein said shingle includes a base layer and said base layer is of substantially greater width than others of said layers.  
   
   
       6 . A high profile composition shingle as claimed in  claim 3  wherein said weather layer and said layers are tapered in length and are of substantially uniform width.  
   
   
       7 . A high profile composition shingle for roofs comprising: 
 a weather layer of composition material having a granulated surface;    a plurality of tapered ribs of composition material spaced across the butt end of said weather layer, each said ribs having a thick end and all of the thick ends positioned near the butt end of said weather layer; and    a butt end rib located adjacent the thick end of said spaced ribs below said weather layer.    
   
   
       8 . A high profile composition shingle as claimed in  claim 8  wherein selected ribs of said spaced ribs are longer than other said ribs.  
   
   
       9 . A high profile composition shingle as claimed in  claim 8  wherein the widths of the spaces between said ribs are greater than the widths of the ribs.  
   
   
       10 . A high profile composition shingle as claimed in  claim 8  wherein the thickness of said butt end rib is substantially greater than the thickness of said weather layer.  
   
   
       11 . A high profile composition shingle as claimed in  claim 8  wherein said tapered ribs abut against said butt end rib and the thickness of said tapered ribs adjacent said butt end rib is substantially the same as the thickness of said butt end rib.  
   
   
       12 . A high profile composition shingle for roofs comprising: 
 a generally rectangular weather layer;    a plurality of underlayers secured to said weather layer, said underlayers together being progressively tapered in length with one end of each of said underlayers being stacked in registry to form the butt end of said shingle said plurality of underlayers being stapled together near said butt end.    
   
   
       13 . A high profile composition shingle for roofs comprising: 
 an elongated weather layer of granule-covered roofing composition;    a plurality of different length underlayment layers bonded to each other at one end of each to form a tapered underlayment bonded to said weather layer, the longest of said underlayment layers being in the order of one half the length of said weather layer, one end of said underlayment layers being bonded to one end of said weather layer to form with said weather layer the butt end of said shingle.    
   
   
       14 . A shingle in accordance with  claim 13  wherein said underlayment layers are all mechanically fastened together at one end.  
   
   
       15 . A shingle in accordance with  claim 16  wherein the mechanical fastening is provided by at least one staple.  
   
   
       16 . A shingle in accordance with  claim 14  wherein said underment layers and said weather layers are of the same width at least in the weather region when installed.  
   
   
       17 . A high profile composition shingle for roofs comprising: 
 a generally rectangular weather layer;    a first underlayer under said weather layer of substantially the same width as and approximately one-half the length of said weather layer;    a second underlayer under said first underlayer of substantially the same width as and substantially shorter than said first underlayer;    a third underlayer under said second underlayer of substantially the same width as and substantially shorter than said second underlayer;    a fourth underlayer under said third underlayer of substantially the same width as and substantially shorter than the third underlayer; and    a fifth underlayer under said fourth underlayer of substantially the same width as and substantially shorter than said fourth underlayer;    said first through fifth underlayers all being of composition roofing material and all said underlayers being stacked together with one end aligned with one end of said weather layer to form a thickened butt end of said high profile composition shingle, said first through fifth underlayers being stapled together at said butt end.
