摘要

A roofing shingle including a buttlap portion and a headlap portion is provided. The roofing shingle includes a coated mat having a roofing mat coated with an organic-based coating material. The coated mat has a width that extends entirely through the buttlap portion and does not extend more than 20% into the headlap portion of the roofing shingle. A water impermeable sheet is adjacent to the coated mat. The sheet has a width that extends from a head edge through at least 80% of the headlap portion and does not extend to a butt edge of the roofing shingle. A nail zone region is formed at an overlap of the coated mat and the water impermeable sheet. The nail zone region is marked by a dissimilar material.
