Abstract: The present invention relates to a roofing tape which allows roofers to determine and consistently apply the proper reveal space of shingles on any roof without measurement. A roofing tape includes a start indicator, a first line indicator, and a plurality of series of indicia on its front surface. The first line indicator is located at a distance from the start indicator equal to the height of the roofing shingles less the overhang requirement of the roofing shingles. Each series of indicia is arranged longitudinally along the roofing tape. Each series of indicia has equal intervals between the first line indicator and the first indicator in the series and between consecutive indicia in the series. The intervals in each series correspond to a spacing within the reveal space tolerance range of the roofing shingles. The roofing tape preferably includes eave adjustment eave adjustment hash marks so that the tape may be adjusted downward to cover all the areas along an irregular eave.
