ABSTRACT:
Fixtures for aligning asphalt composition strip shingles for roofing and siding are disclosed. An elongated alignment guide is provided for supporting the lower edges of a plurality of shingles to be laid on a roof or attached to a building wall. In one embodiment, the alignment guide comprises a plurality of sections, some equal in length to two standard strip shingles; and some, to a single standard strip shingle, thereby permitting the assembly of alignment guides of various lengths from one to a desired number of standard shingle lengths. A clamping device attached to the alignment guide includes a pair of essentially flat, opposed jaws which are connected by spring-biased levers, for compressing the jaws together to grip a shingle in a previously laid row of shingles. A horizontal stop on the clamp or the guide positions the device so that successive rows of strip shingles are staggered relative to each other.
