A roofing shingle is provided. The roofing shingle includes an overlay sheet including a headlap portion and a tab portion and an underlay sheet secured to the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. Said underlay sheet has a substantially uniform thickness. A reinforcement member is secured to the headlap portion. The reinforcement member is formed from a material selected from the group consisting of paper, film, scrim, woven, and non-woven material. The reinforcement member and the portion of the headlap portion to which the reinforcement member is secured to improve nail pull-through. At least some of the reinforcement member does not overlap the overlapping regions of the headlap portion and the underlay sheet. Said reinforcement member provides said overlay sheet with a non-uniform thickness.
