Abstract
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.
Claims16
A shingle comprising a tab portion adapted to be exposed when installed on a roof and a headlap portion adapted to be unexposed when installed on a roof, and including an adhesive impregnated mat with upper and lower surfaces, with granules on the upper surface, and including at least one overlay of granule covered adhesive comprising a narrow band along the upper surface of the headlap portion creating a thicker portion along the shingle than the rest of the shingle, wherein granules on said upper surface are beneath said overlay, with the overlay comprising any one of:
- (a) means providing a fastening zone for receiving fasteners therethrough, for fastening the shingle to a roof;
- and
- (b) means providing a contact zone for adhesive of an overlying tab portion of a next-overlying shingle when the shingle is installed on a roof, for forming a water barrier against water entering between overlying and next-underlying shingles at the location of said overlay.
