Hip and ridge roofing material

Abstract

A shingle blank is provided including a substrate coated with an asphalt coating and including a first fold region, a second fold region, a third region, a lower edge and an upper edge. The shingle blank has a length. The first fold region extends substantially across the length of the shingle blank. The second fold region extends substantially across the length of the shingle blank and is positioned between the first fold region and the third region. A first perforation line is positioned between the second fold region and the third region. A second perforation line is positioned between the first fold region and the second fold region. The first and second perforation lines are sufficient to facilitate folding of the first fold region and the second fold region on top of the third region to form a three layered stack configured to be applied across a ridge or hip.

       2 . The shingle blank of  claim 1  in which the first fold region, the second fold region and the third region are covered with prime granules. 
   
   
       3 . The shingle blank of  claim 1  in which the three layered stack is positioned at one end of the shingle blank. 
   
   
       4 . The shingle blank of  claim 1  in which the first fold region and the second fold region have a height, wherein the height of the first fold region and the second fold region are different. 
   
   
       5 . The shingle blank of  claim 1  in which the first perforation line is covered by a reinforcement material. 
   
   
       6 . The shingle blank of  claim 5  in which the reinforcement material is positioned on an upper surface of the shingle blank. 
   
   
       7 . The shingle blank of  claim 6  in which the reinforcement material extends substantially across the length of the shingle blank. 
   
   
       8 . The shingle blank of  claim 5  in which the reinforcement material is formed from a polymeric material. 
   
   
       9 . The shingle blank of  claim 1  in which the shingle blank has a lower surface, wherein a release tape is positioned on the lower surface. 
   
   
       10 . The shingle blank of  claim 1  in which a sealant line is positioned on the first fold region. 
   
   
       11 . The shingle blank of  claim 1  wherein at least one additional perforation line extends substantially across the shingle blank in a direction substantially perpendicular to the lower edge of the shingle blank. 
   
   
       12 . The shingle blank of  claim 1  in which the three layered stack has a leading edge. 
   
   
       13 . 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 a first fold region, a second fold region, a third region, a lower edge and an upper edge, the shingle blank having a length, the first fold region extending substantially across the length of the shingle blank, the second fold region extending substantially across the length of the shingle blank and positioned between the first fold region and the third region;   applying a reinforcement material to a portion of an upper surface of the asphalt coated sheet;   applying a surface layer of granules to the upper surface of the asphalt coated sheet;   forming a first perforation line between the second fold region and the third region; and   forming a second perforation line between the first fold region and the second fold region.   
   
   
       14 . The method of  claim 13  in which the roofing material has a lower surface, wherein a release tape is applied to a portion of the lower surface. 
   
   
       15 . The method of  claim 13  in which one additional perforation line extends substantially across the shingle blank in a direction substantially perpendicular to the lower edge of the roofing material. 
   
   
       16 . The method of  claim 15  in which hip or ridge roofing materials are formed by separation of the shingle blank along the at least one additional perpendicular perforation line and folding the first and second perforation lines to form a three layered stack. 
   
   
       17 . 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 including a first fold region, a second fold region, a third region, a lower edge and an upper edge, the shingle blank having a length, the first fold region extending substantially across the length of the shingle blank, the second fold region extending substantially across the length of the shingle blank and positioned between the first fold region and the third region, a first perforation line positioned between the second fold region and the third region, a second perforation line positioned between the first fold region and the second fold region, wherein at least one additional perforation line extends across the shingle blank in a direction substantially perpendicular to the lower edge of the shingle blank;   separating the shingle blank along the at least one additional perforation line to form separated shingle blanks;   folding the separated shingle blanks along the first and second perforation lines to form a three layered stack; and   installing the hip and ridge shingles across a hip or ridge.   
   
   
       18 . The method of  claim 17  in which the three layered stack includes a sealant line positioned on the top of the three layered stack, wherein the three layered stack of subsequent hip or ridge shingles are installed over the sealant line of previously installed hip or ridge shingles. 
   
   
       19 . A shingle blank comprising:
 a substrate coated with an asphalt coating and including a first fold region, a second fold region, a third region, a lower edge and an upper edge, the shingle blank having a length, the first fold region extending substantially across the length of the shingle blank, the second fold region extending substantially across the length of the shingle blank and positioned between the first fold region and the third region;   a first perforation line positioned between the second fold region and the third region;   a second perforation line positioned between the first fold region and the second fold region; and   at least two additional perforation lines extending substantially across the shingle blank in a direction substantially perpendicular to the lower edge of the shingle blank   wherein the at least two additional perforation lines are sufficient to facilitate separation of the shingle blank and the first and second perforation lines are sufficient to facilitate folding of the first fold region and the second fold region on top of the third region to form a three layered stack configured to be applied across a ridge or hip.   
   
   
       20 . The shingle blank of  claim 19  in which the first perforation line is covered by a reinforcement tape.
