A shingle, an array of shingles, and a process for producing the shingles, either of the field shingle type, or of the hip, ridge or rake type, wherein the shingles have a shortened headlap portion for purposes of reducing the amount of material necessary to make the shingle, wherein each of the shingles has a fastening zone for receiving fasteners therethrough, which fastening zone is an overlay of granule covered adhesive, and is in the headlap portion, and wherein a contact zone layer of adhesive is provided on the rear of the tab portion of the shingle, for contact against the overlay of granule covered adhesive when a next-overlying shingle is arranged in an array above a next-underlying shingle.
