System of placement of shingles on a roof, a plurality of shingles thus placed, and a roof with such shingles thereon

Abstract

A system of placement of adjacent roofing shingles on a roof is provided, whereby the horizontal spacing of adjacent shingles, the vertical placement of shingles, and the proper angular orientation of shingles is provided, due to a system of indicia on a visible upper surface of the shingles. A plurality of adjacent appropriately oriented shingles and appropriately placed shingles are provided, as is a roof having a plurality of shingles laid up thereon in courses.

1 . A system of placement of adjacent roofing shingles of the real or simulated tile, slate or shake types on a roof, such that the placement of adjacent shingles when laid up on a roof as to lateral spacing, vertical spacing and alignment, is in accordance with a predetermined desired placement, comprising:
 (a) a plurality of shingles having top and bottom surfaces, upper and lower edges and right and left side edges, with the shingles being adapted to be laid up on a roof with their bottom surfaces disposed toward the roof and their top surfaces facing generally upwardly; and   (b) visual indicia on top surfaces of the shingles;   (c) with the visual indicia including at least one line disposed on each said shingle;   (d) with said at least one line being non-perpendicular to and non-parallel to any of said upper, lower, right and left side edges of said shingle; and   (e) with a projected extension of said at least one line of a given shingle being in a predetermined visual intersection with at least one different line of a next-adjacent shingle when the two adjacent shingles are laid up on a roof with the predetermined desired placement and not being in the predetermined visual intersection with said at least one different line of a next-adjacent shingle when the two adjacent shingles are laid up on a roof and not having the predetermined desired placement.   
   
   
       2 . The system of  claim 1 , wherein said at least one line of each said given shingle is at an acute angle to a side edge of a said shingle, and wherein said at least one different line of a said adjacent shingle is at an acute angle to a side edge of said adjacent shingle. 
   
   
       3 . The system of  claim 1 , wherein each said shingle has at least a second line comprising a visual indicium on a top surface of said shingle. 
   
   
       4 . The system of  claim 3 , with a projected extension of said at least a second line visually aligning with an at least one different second line of a next-adjacent shingle when the two adjacent shingles are laid up on a roof with the predetermined desired placement and not aligning with an at least one said different second line of a next-adjacent shingle when the two adjacent shingles are laid up on a roof and not having the predetermined desired placement. 
   
   
       5 . The system of  claim 3 , wherein each at least said second line is generally perpendicular to a side edge of the shingle on which the at least one said different second line is disposed. 
   
   
       6 . The system of  claim 4 , wherein each said at least one said different second line is at an acute angle to a side edge of the shingle on which the second line is disposed. 
   
   
       7 . A system of placement of adjacent roofing shingles of the real or simulated tile, slate or shake types on a roof, such that the placement of adjacent shingles, when laid up on a roof as to lateral spacing, vertical spacing and alignment, is in accordance with a predetermined desired placement, comprising:
 (a) a plurality of shingles having top and bottom surfaces, upper and lower edges and right and left side edges, with the shingles being adapted to be laid up on a roof with their bottom surfaces disposed toward the roof and their top surfaces facing generally upwardly; and   (b) visual indicia on top surfaces of the shingles;   (c) with the visual indicia including at least one line disposed on each said shingle;   (d) with said at least one line being non-perpendicular to and non-parallel to any of said upper, lower, right and left side edges of said shingle;   (e) at least one mark comprising visual indicia on a top surface of each said shingle; and   (f) with a projected extension of said at least one line of a given shingle being in a predetermined visual intersection with a different mark of a next adjacent shingle when the two adjacent shingles are laid up on a roof with the predetermined placement and not being) in the predetermined visual intersection with said different mark of a next adjacent shingle when the two adjacent shingles are laid up on a roof and not having the predetermined desired placement.   
   
   
       8 . The system of  claim 7 , wherein each said mark on each said shingle comprises the intersection of a different line with a side edge of the shingle on which the different line is disposed. 
   
   
       9 . The system of  claim 8 , wherein said different line is a substantially horizontal line. 
   
   
       10 . A plurality of adjacent shingles disposed on a roof in accordance with the system of any one of  claims 1 - 9 . 
   
   
       11 . A roof having a plurality of shingles laid up in courses in accordance with the system of any one of  claims 1 - 9 .
