Hip And Ridge Roofing Material

Abstract

A shingle blank is provided comprising a substrate coated with an asphalt coating and configured to include a prime region. The asphalt coating includes an upper section and a lower section, the upper section is positioned above the substrate and the lower section is positioned below the substrate. A web is applied to the lower section of the prime region. At least one perforation line is positioned in the shingle blank. The at least one perforation line is sufficient to facilitate separation of the shingle blank.

1 . A shingle blank comprising:
 a substrate coated with an asphalt coating and configured to include a prime region, the asphalt coating including an upper section and a lower section, the upper section being positioned above the substrate, the lower section being positioned below the substrate; and   a web applied to the lower section of the prime region;   wherein at least one perforation line is positioned in the shingle blank, the at least one perforation line being sufficient to facilitate separation of the shingle blank.   
     
     
         2 . The shingle blank of  claim 1  in which the blank has a length and wherein the at least one perforation line extends substantially across the shingle blank in a direction substantially perpendicular to the length of the shingle blank. 
     
     
         3 . The shingle blank of  claim 1  in which the at least one perforation line includes a plurality of perforations. 
     
     
         4 . The shingle blank of  claim 3  in which the perforations have a length of about 0.25 inches. 
     
     
         5 . The shingle blank of  claim 3  in which the perforations are spaced apart a distance of about 0.25 inches from edge to edge. 
     
     
         6 . The shingle blank of  claim 3  in which the perforations extend through the substrate, the upper and lower sections of the asphalt coating and the web. 
     
     
         7 . The shingle blank of  claim 1  in which the web has a depth of approximately 0.03125 inches. 
     
     
         8 . A method of manufacturing an asphalt-based roofing material, comprising the steps of:
 coating a substrate with an asphalt coating to form an asphalt coated sheet, the asphalt coated sheet including an upper section and a lower section;   applying a surface layer of granules to the upper section of the asphalt coated sheet;   applying a web to the lower section of the asphalt coated sheet; and   forming at least one perforation line substantially across the asphalt coated sheet.   
     
     
         9 . The method of  claim 8  in which the shingle blank has a length and wherein the at least one perforation line extends substantially across the shingle blank in a direction substantially perpendicular to the length of the shingle blank. 
     
     
         10 . The method of  claim 9  in which the at least one perforation line includes a plurality of perforations. 
     
     
         11 . The method of  claim 10  in which the perforations have a length of about 0.25 inches. 
     
     
         12 . The method of  claim 10  in which the perforations are spaced apart a distance of about 0.25 inches from edge to edge. 
     
     
         13 . The method of  claim 10  in which the perforations extend through the substrate, the upper and lower sections of the asphalt coated sheet and the web. 
     
     
         14 . A method of installing an asphalt-based roofing material, comprising the steps of:
 providing an asphalt-based shingle blank having a substrate coated with an asphalt coating and configured to include an upper section and a lower section, a web is applied to the lower section, wherein at least one perforation line is positioned substantially across the asphalt-based shingle blank;   forming hip or ridge shingles by separating the shingle blank along the at least one perforation line; and   installing the hip and ridge shingles upon a hip or ridge.   
     
     
         15 . A shingle blank comprising:
 a substrate coated with an asphalt coating and configured to include a prime region, the asphalt coating including an upper section and a lower section, the upper section being positioned above the substrate, the lower section being positioned below the substrate; and   a web applied to the lower section of the prime region;   wherein at least one notch is positioned in the shingle blank, the at least one notch being sufficient to facilitate separation of the shingle blank.   
     
     
         16 . The shingle blank of  claim 15  in which the shingle blank has a length and wherein the at least one notch extends substantially across the prime region of the shingle blank in a direction substantially perpendicular to the length of the shingle blank. 
     
     
         17 . The shingle blank of  claim 15  in which the at least one notch extends through the substrate, the upper and lower sections of the asphalt coating and the web. 
     
     
         18 . A shingle blank comprising:
 a substrate coated with an asphalt coating and configured to include a prime region, the asphalt coating including an upper section and a lower section, the upper section being positioned above the substrate, the lower section being positioned below the substrate; and   a web applied to the lower section of the prime region;   wherein at least one courtesy cut is positioned in the shingle blank, the at least one courtesy cut being sufficient to facilitate separation of the shingle blank.   
     
     
         19 . The shingle blank of  claim 18  in which the shingle blank has at least one courtesy cut positioned in the prime regions and at least one courtesy cut positioned in a headlap region. 
     
     
         20 . The shingle blank of  claim 19  in which the at least one courtesy cut positioned in the prime region substantially aligns with the at least one courtesy cut positioned in the headlap region
