ABSTRACT:
A roof shingle alignment system employs three separate types of line bar tools for setting aligned chalklines. The first line bar is used to strike chalklines vertically on roof surfaces and for setting the starter horizontal chalkline. The second line bar is placed on the starter chalkline and is used to strike horizontal chalklines across the roof surface. A third line bar is configured to be placed on the peak of the roof for setting horizontal chalklines near the roof's ridge for cutout and hip cap lines.
