Hip and ridge shingle, method and apparatus for making, and method of using same

Abstract

A web of roofing material ( 20 ) is perforated for segmentation into plural trapezoidal-shaped shingles ( 22 ). In view of the perforation ( 24 ) of the web ( 20 ), the trapezoidal-shaped shingles ( 22 ) are pre-configured for use as hip and ridge shingles advantageously having edges pre-shaped to align upon installation to present an essentially straight line of edges of contiguous shingles. The hip and ridge shingles are detachable from the web at the perforation to facilitate use of the shingles on a roofing obliquity ( 40 ). A method of applying shingles to a roof includes segmenting a pre-perforated web of roofing material into individual shingles, positioning a first trapezoidal shaped shingle on the roofing obliquity ( 40 ) so that the major parallel edge thereof is bent across a bend line of the roofing obliquity and so that the major parallel edge of the first trapezoidal shaped shingle serves as a leading exposed edge of the shingle, affixing the first trapezoidal shape shingle to the roof understructure, and using a sealant strip ( 36 ) of the first shingle as a guide for positioning a second shingle over the first shingle. A method of making the roofing material comprises forming a covering material on a first surface of a substrate; cutting the substrate into a web, the web comprising plural trapezoidal shaped shingles; and, forming perforations in the web to facilitate segmentation of the web into the plural trapezoidal shaped shingles.

       6 . The web of  claim 5 , wherein the major parallel side has a length of 12.5 inch and the minor parallel side has a length of 10.5 inch.  
   
   
       7 . The web of  claim 1 , wherein the web has two parallel web edges, wherein a sealant strip is formed on the web to provide an alignment guide.  
   
   
       8 . The web of  claim 7 , wherein the sealant strip is formed parallel to and midway between the two parallel web edges.  
   
   
       9 . The web of  claim 1 , wherein the web has two parallel web edges, and wherein a shadow line is formed on the web parallel to the two parallel web edges.  
   
   
       10 . A method of applying shingles to a roof comprising: 
 segmenting a pre-perforated web of roofing material into individual shingles, each individual shingle having a trapezoidal shape, each individual shingle having two parallel side edges including a major parallel edge and a minor parallel edge, the major parallel side and the minor parallel side being parallel to one another, the major parallel side having a length greater than the minor parallel side, each shingle having a sealant strip extending perpendicularly to the parallel edges;    positioning a first trapezoidal shaped shingle on roof understructure at a roofing obliquity so that the major parallel edge of the first trapezoidal shaped shingle serves as a leading exposed edge of the first shingle;    affixing the first trapezoidal shape shingle to the roof understructure;    using the sealant strip of the first shingle as a guide for positioning a second shingle over the first shingle, the second shingle being positioned so that the major parallel edge serves as a leading exposed edge of the second shingle, and whereby an exposed portion of the second shingle overlies a butt portion of the first shingle.    
   
   
       11 . The method of  claim 10 , wherein the step of affixing the first trapezoidal shape shingle to the roof understructure comprises affixing a butt portion of the first shingle to the minor parallel edge of the first shingle.  
   
   
       12 . The method of  claim 10 , further comprising positioning the major parallel edge of the second shingle over the first shingle so that the major parallel edge of the second shingle just covers the sealing strip of the first shingle.  
   
   
       13 . The method of  claim 10 , wherein the roofing obliquity is a roof ridge.  
   
   
       14 . The method of  claim 10 , wherein the roofing obliquity is a roof hip.  
   
   
       15 . The method of  claim 10 , wherein the roofing obliquity is a ridge vent cap.  
   
   
       16 . A method of making a roofing material comprising: 
 forming a covering material on a first surface of a substrate;    cutting the substrate into a web, the web comprising plural trapezoidal shaped shingles;    forming perforations in the web to facilitate segmentation of the web into the plural trapezoidal shaped shingles.    
   
   
       17 . The method of  claim 16 , wherein the step of forming the covering material comprises forming a sealant strip on the substrate.  
   
   
       18 . The method of  claim 16 , wherein the step of forming the covering material comprises forming a shadow line on the substrate.  
   
   
       19 . The method of  claim 16 , wherein the cutting and forming of the perforations is controlled whereby each shingle has a major parallel side and a minor parallel side and two non-parallel sides, the major parallel side and the minor parallel side being parallel to one another, the major parallel side having a length greater than the minor parallel side.  
   
   
       20 . A cutting head for producing webs of roofing material having plural shingle in each web, the cutting head having a peripheral surface configured to have plural axial regions configured to operate upon a corresponding plurality of production lanes of webs, each axial region of the peripheral surface comprising both cutting elements and perforating elements, the cutting elements of a first axial region being offset around a periphery of the peripheral surface with respect to the cutting elements of an adjacent axial region, and the perforating elements of a first axial region being offset around a periphery of the peripheral surface with respect to the perforating elements of an adjacent axial region.
