ABSTRACT:
The disclosure relates to the field of composition shingles and in particular the types of shingle known as strip or tab shingles. Heretofore shingles having nonuniform random or jagged butt edges have relied on locating indicia on the upper covered portions of the leading and trailing edges thereof, or on the upper edge of the overall shingle, to aid in positioning these shingles relative to one another on a roof deck. Tab shingles have been able to eliminate at least some of the locating indicia in these areas by relying on uniformly sized and positioned slot cutouts to locate the uniform butt edges of the overlapping shingle relative to the shingle being overlapped. The present shingle includes at least one slot dividing the butt edge into two tabs and a knife slit in one of the tabs. The lower edge of the tabs corresponding to a portion of the butt edge of the shingle include specifically shaped locating edges. These locating edges contribute to the jagged nonuniform appearance of the shingle and are used to determine proper offset alignment and butt edge exposure. The knife slit extends across the butt portion of the first tab to define an overlap tab along the leading edge of the shingle by positioning this overlap tab to cover a portion of the adjacent shingle, a double thick shingle portion is created and a novel fastening system may be employed.
