Abstract: A roofing layout tape is calibrated to show the linear increments between rows or courses of shingles, and also the incremental bond line markings applied from the lateral eaves of a roof to provide shingle overhang for runoff at the eaves and lateral stagger for each horizontal course of shingles. The device comprises a flexible tape retractably housed within a case or reel. While the present roofing layout tape may include conventional linear markings (inches, feet, etc.), it also includes a series of course and bond line markings along each edge of the top surface (i.e., the inwardly disposed surface when the tape is coiled). One set of edge markings applies to conventional or three tab shingles, while the opposite edge markings apply to dimensional or architectural shingles. A method of using the present roofing layout tape for laying out shingle course lines and bond lines, is also disclosed.
