Patent ID: 6895724

Claim:
A process for installing a laminated hip and ridge asphalt shingle along intersecting planes of a roof having an intersecting angle of less than 180° comprising the steps of: 1) providing a hip and ridge asphalt shingle of essentially rectangular configuration adapted to be bent along a fold line to conform to a roof hip or ridge comprising three layers: a first layer having a top surface and an undersurface comprising two L-shaped portions each having a horizontal portion and a vertical portion, a top surface and an undersurface wherein said horizontal portions are superimposed on each other and said vertical portions are positioned adjacent to each other forming a gap therebetween, said gap allowing bending of the layer to conform to a hip or ridge on a roof surface, wherein portions of said top surface are coated with a lamination adhesive, and portions of said undersurface are undercoated with a self-seal adhesive; a second layer having a top surface and an undersurface and comprising a head portion and a butt portion, superimposed on said first layer and adhered thereto by the lamination adhesive on said first layer, wherein at least a portion of the top surface is coated with a lamination adhesive; and a third layer having a top surface and an undersurface covering the head portion of said second layer; wherein the top surface of each layer is coated with mineral granules; 2) bending said laminated hip and ridge asphalt shingle along its gap in said first layer for conformance to the intersecting planes of said roof; 3) placing a first laminated hip and ridge asphalt shingle on the intersecting planes of said roof and pressing it for adherence thereto; 4) nailing the first laminated hip and ridge asphalt shingle to the roof deck on both sides of the hip or ridge; 5) placing a second laminated hip and ridge asphalt shingle over the intersecting planes of said roof so that the butt portion thereof overlaps the head portion of said first laminated hip and ridge asphalt shingle and bending and pressing it for adherence thereto; 6) nailing the second laminated hip and ridge asphalt shingle to the roof deck on both sides of the hip or ridge; 7) repeating steps 5 and 6 for mounting and securing a successive number of the hip and ridge asphalt shingles to complete the installation over the intersecting planes of the roof.
