Apparatus for accurate installation of roof shingles

Abstract

An apparatus for accurately locating shingles on a roof. The apparatus includes a sheet with two measuring edges. Each edge has a number of spaced apart measuring points located along each edge. A number of hashed lines are located on the sheet's surface. The distance between the lines are pre-determined. The spaced apart hashed lines being disposed substantially parallel relative to each other along the sheet surface. A first series of two spaced apart points are spaced apart an equal distance from each other. The points are located along spaced apart hashed lines. Another spaced apart set of points are located between the first series of spaced apart points. The second series of points are staggered relative to the first series. An internal measuring zone is located within the boundaries of the sheet. The zone has an icon of a pre-determined length and a predetermined height. The hashed lines. the points and the internal measuring zone provide reference locations to permit one or more shingles to align therewith.
