Abstract
The present disclosure relates generally to roofing products, for example, shingles suitable for covering and protecting the roofs of houses, buildings, and other structures. The present disclosure relates more particularly to a roofing shingle including an upper edge, a lower edge, a first end, a second end, a headlap section, and an exposed section. A nail zone extends across the roofing shingle from the first end to the second end within the headlap section. The roofing shingle includes a top shingle layer including a top surface and a bottom surface. A reinforcement strip is secured to the bottom surface of the top shingle layer and overlaps with the nail zone. Further, a self-sealing material is disposed within the nail zone and is configured to form a seal around a mechanical fastener that punctures the roofing shingle in order to secure the roofing shingle to an underlying roof structure.
