SHINGLE WITH ENHANCED BONDING

Abstract:

A shingle which includes a substrate, granules deposited on the substrate, a first material strip applied to the top of the substrate, a second material strip applied to the bottom of the substrate, and an adhesive applied to the second material strip. The second material strip is positioned along an edge of the substrate such that when a shingle is applied to a roof overlaying an existing shingle, the adhesive adheres the second material strip of the overlaying shingle to the first material strip of the existing shingle. The second material strip is applied to the bottom of the substrate prior particles being applied to the bottom surface of the substrate.
