Abstract: Roofing shingles have a top surface, a bottom surface, a headlap portion, and a bead of tab sealant that is configured to bond to an underlying shingle when the shingle is applied on a roof. The tab sealant has a thickness that causes it to extend beyond a face of the bottom surface of the shingle. The headlap portion has a depression extending horizontally across the shingle when shingle is applied to the roof, the depression being spaced from a top edge of the shingle by a distance that will allow the depression to be aligned with the tab sealant of a complementary shingle when the shingles are assembled in complementary pairs, back to back in a bundle.
