Roofing shingles and methods of making and affixing same

Abstract

A roofing shingle ( 20 ) comprises a web ( 22 ) having a shingle major dimension ( 24 ) and a shingle minor dimension ( 26 ). The web ( 22 ) in turn comprises a headlap portion ( 30 ) and plural tabs ( 32 ). The headlap portion ( 30 ) extends along a web first edge ( 34 ) which is parallel to the shingle major dimension. The plural tabs ( 32 ) are formed along a web second edge ( 36 ) which is parallel to the web first edge. Adjacent ones of the plural tabs ( 32 ) are separated by a cut out ( 40 ). The cut out ( 40 ) extends in the shingle minor dimension ( 26 ). As formed, each of the plural tabs ( 30 ) has a greater extent along the shingle minor dimension ( 26 ) than along the shingle major dimension ( 24 ).

1 . A roofing shingle comprising a web having a shingle major dimension and a shingle minor dimension, the web comprising:
 a headlap portion extending along a web first edge, the web first edge being parallel to the shingle major dimension;   plural tabs formed along a web second edge, the web second edge being parallel to the web first edge, adjacent ones of the plural tabs being separated by a cut out, the cut out extending in the shingle minor dimension, each of the plural tabs having a greater extent along the shingle minor dimension than along the shingle major dimension.   
     
     
         2 . The roofing shingle of  claim 1 , wherein for each of the plural tabs, a ratio of a tab extent along the shingle minor dimension to a tab extent along the shingle major dimension is in a ratio of 136:113. 
     
     
         3 . The roofing shingle of  claim 1 , wherein each of the plural tabs measures substantially 8 and ½ inches along the shingle minor dimension and substantially 7 and 1/16 inches along the shingle major dimension. 
     
     
         4 . The roofing shingle of  claim 3 , wherein each tab has a corner defined by the cut out, and wherein the corner is angularly truncated. 
     
     
         5 . The roofing shingle of  claim 3 , wherein the web measures substantially 22 and 11/16 inches in the shingle major dimension and substantially 18 and ½ inches in the shingle minor dimension. 
     
     
         6 . The roofing shingle of  claim 1 , wherein a ratio of a tab extent along the shingle minor axis to measurement of the web along the shingle minor axis is in a ratio of 17:20. 
     
     
         7 . The roofing shingle of  claim 1 , wherein the plural tabs comprise material of contrasting coloration relative to the headlap portion. 
     
     
         8 . The roofing shingle of  claim 1 , wherein the headlap portion comprises a sealant on an upper surface thereof. 
     
     
         9 . The roofing shingle of  claim 8 , wherein the headlap portion comprises two linear stripes of sealant, both a first stripe of sealant and a second stripe of sealant being by formed by discontinuous segments of sealant material, and wherein the segments of the first stripe of sealant and the segments of the second stripe of sealant are staggered relative to one another along the shingle major dimension. 
     
     
         10 . The roofing shingle of  claim 9 , wherein the segments of the first stripe of sealant and the segments of the second stripe of sealant are staggered to form offset channels along the shingle minor direction. 
     
     
         11 . A roofing shingle comprising a web having a shingle major dimension and a shingle minor dimension, the web comprising:
 a headlap portion extending along a web first edge, the web first edge being parallel to the shingle major dimension;   plural tabs formed along a web second edge, the web second edge being parallel to the web first edge, adjacent ones of the plural tabs being separated by a cut out;   wherein the headlap portion comprises two linear stripes of sealant, both a first stripe of sealant and a second stripe of sealant being by formed by discontinuous segments of sealant material, and wherein the segments of the first stripe of sealant and the segments of the second stripe of sealant are staggered relative to one another along the shingle major dimension.   
     
     
         12 . The roofing shingle of  claim 11 , wherein the segments of the first stripe of sealant and the segments of the second stripe of sealant are staggered to form offset channels along the shingle minor direction. 
     
     
         13 . The roofing shingle of  claim 11 , wherein the cut out extends in the shingle minor dimension, each of the plural tabs having a greater extent along the shingle minor dimension than along the shingle major dimension. 
     
     
         14 . A method of applying roofing shingle to a roof, each shingle comprising a web having a shingle major dimension and a shingle minor dimension, the web comprising:
 a headlap portion extending along a web first edge, the web first edge being parallel to the shingle major dimension;   plural tabs formed along a web second edge, the web second edge being parallel to the web first edge, adjacent ones of the plural tabs being separated by a cut out, the cut out extending in the shingle minor dimension, each of the plural tabs having a greater extent along the shingle minor dimension than along the shingle major dimension;   wherein the method comprises:   affixing a first shingle to the roof,   positioning a second shingle over a portion of the first shingle in such a manner that a degree of exposure of the cutout of the first shingle provides a tab of the first shingle with a desired visibly perceived geometrical configuration, the degree of exposure depending on a situation characteristic of the roof.   
     
     
         15 . The method of  claim 14 , wherein the situational characteristic of the roof is angle of roof inclination relative to a ground plane. 
     
     
         16 . The method of  claim 14 , wherein the situational characteristic of the roof is roof height relative to a ground plane. 
     
     
         17 . The method of  claim 14 , wherein the desired visibly perceived geometrical configuration of the tab is a square.
