  • Patent number: 8479474
    Abstract: A shingle installation device comprises a body that maintains an alignment stop and a positioning stop that are parallely spaced by a predetermined distance to provide suitable overlap of successively installed shingles. The body also maintains a retainer that forms a gap that is configured to receive and retain the position of a shingle that is being installed. Thus, when the installation device is positioned such that the alignment stop rests against an edge of an installed shingle, an edge of the shingle to be installed is placed within the gap where it is retained in its correct position until the shingle is fastened to the surface being covered.

  • Publication number: 20070266583
    Abstract: A flat lay-out tape for roofers that eliminates errors and saves time in striking chalk lines for aligning rows of shingles. The flat design allows the tape to lay flush against the roof surface, which facilitates accurate measuring and striking. The lay-out tape prevents errors by providing row indicators for different shingles on different sides of the tape. In the preferred embodiment, row indicators for standard shingles are shown on one side of the tape, and row indicators for architectural shingles are provided on the other side. Standard measuring tape markings can also be provided on either side of the tape. In operation, the terminal end of a lay-out tape is tacked down near the bottom of a roof, near a side edge of the roof, and the tape is extended over the apex of the roof. The same is done with a second lay-out tape, near the opposite side edge of the roof. A chalk line is then stretched, and struck, between corresponding indicators of the two lay-out tapes.
