Apparatus for accurate installation of roof shingles

An apparatus for accurately locating shingles on a roof, the apparatus comprising:

• a sheet having a first measuring edge and a second measuring edge, each measuring edge having a plurality of spaced apart measuring points located therealong;
• a plurality of elongate spaced apart hashed lines located on a sheet surface, the distance between the hashed lines being pre-determined, the spaced apart hashed lines being disposed substantially parallel relative to each other along the sheet surface,
• a first series of first and second spaced apart points spaced apart an equal distance from each other, the first and second spaced apart points being located along first and second spaced apart hashed lines;
• a second series of third spaced apart points located between the first series of first and second spaced apart points, the second series of the third spaced apart points being staggered relative to the first series of the first and second spaced apart points;
• and
• an internal measuring zone located between the first and the second measuring edges, the internal measuring zone having located thereon an icon of a pre-determined length and a predetermined height,
• the spaced apart hashed lines, the spaced apart points and the internal measuring zone being disposed across the sheet so as to provide reference locations to permit one or more shingles to align therewith.
