Laminated starter shingle for a roof covering

Abstract

A method of covering a roof deck includes laying a course of starter shingles in a side-by-side relationship at an eave edge of a roof deck. A starter shingle of the course of starter shingles is a laminated starter shingle comprising an underlay sheet laminated below an overlay sheet. A plurality of successive generally horizontal courses of covering shingles are laid above the course of starter shingles. The covering shingles in each of the courses of covering shingles are laid in a side-by-side relationship and horizontally offset from the covering shingles in adjacent courses. Each covering shingle of the courses of covering shingles includes a headlap portion and a butt portion. The butt portion includes a plurality of tabs separated by cutouts. The starter shingles include an exposed portion extending between the tabs of the covering shingles.

         32 . The laminated starter shingle of  claim 28 , wherein the front edge of the overlay sheet is aligned with the front edge of the underlay sheet. 
     
     
         33 . The laminated starter shingle of  claim 28 , further comprising a bead of adhesive applied to a bottom surface of the underlay sheet. 
     
     
         34 . A roof covering comprising:
 a course of starter shingles laid in a side-by-side relationship at an cave edge of a roof deck, wherein a starter shingle of the course of starter shingles is a laminated starter shingle comprising:
 an overlay sheet including an asphalt coated mat and having front, rear, left and right edges that define a first rectangle having a first height and a first width; and 
 an underlay sheet including an asphalt coated mat and having front, rear, left and right edges that define a second rectangle having a second height and a second width, the underlay sheet being laminated below the overlay sheet such that an entirety of the underlay sheet is covered by the overlay sheet; 
 wherein the first height is greater than the second height, and the first width is equal to the second width; and 
   a plurality of successive generally horizontal courses of covering shingles laid above the course of starter shingles, the covering shingles in each of the courses of covering shingles being laid in a side-by-side relationship and vertically offset from the covering shingles in adjacent courses,   wherein each covering shingle of the courses of covering shingles includes a headlap portion and a butt portion, the butt portion including a plurality of tabs separated by cutouts,   wherein the starter shingles include an exposed portion visible between the tabs of the covering shingles.   
     
     
         35 . The roof covering of  claim 34 , wherein the butt portion of each covering shingle includes a butt edge and the underlay sheet of each starter shingle includes a lower edge, and wherein the butt edge the covering shingles in a first course of the covering shingles and the lower edge of the starter shingles are vertically aligned to defuse a lower edge of the starter shingle. 
     
     
         36 . The roof covering of  claim 34 , wherein a lower edge of the covering shingles in a first course of the covering shingles is vertically aligned with the lower edge of the starter shingles. 
     
     
         37 . The roof covering of  claim 34 , wherein the exposed portions of the starter shingles have an overall color appearance that is substantially similar to an overall color appearance of the covering shingles. 
     
     
         38 . The roof covering of  claim 34  wherein each of the covering shingles is a laminated shingle comprising an overlay member having a h.eadlap portion and a butt portion, and an underlay member fixedly attached to a rear surface of the butt portion of the overlay member, and wherein a height of the overlay member is greater than a height of the underlay member. 
     
     
         39 . The roof covering of  claim 38 , wherein a difference between a height of the underlay sheet of each starter shingle and a height of the underlay member of each covering shingle is greater than about one inch. 
     
     
         40 . The roof covering of  claim 34 , wherein an overall height of each of the covering shingles is greater than an overall height of each of the starter shingles. 
     
     
         41 . The roof covering of  claim 34 , wherein an overall height each of the covering shingles is at least one inch greater than an overall height of each of the starter shingles. 
     
     
         42 . The roof covering of  claim 34 , wherein the first height is approximately twice the second height. 
     
     
         43 . The roof covering of  claim 34 , wherein the overlay sheet further comprises a layer of granules applied to an upper surface of the asphalt coated mat. 
     
     
         44 . The roof covering of  claim 34 , wherein the underlay sheet further comprises a layer of granules applied to an upper surface of the asphalt coated mat. 
     
     
         45 . The roof covering of  claim 34 , wherein the front edge of the overlay sheet is aligned with the front edge of the underlay sheet.
