A roofing shingle includes an overlay sheet, an underlay sheet, and a reinforcement member. The overlay sheet includes a headlap portion and a tab portion, wherein the overlay sheet has an overlay sheet height. The underlay sheet is secured to a bottom surface of the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. The reinforcement material is secured to a top surface of the headlap portion of the overlay sheet, wherein the reinforcement material is configured to improve nail pull-through, wherein the reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet.

A roofing shake includes a first end and an opposite second end. The roofing shake has a tapered profile such that the second end is thicker than the first end. A bottom surface is configured to face a roofing structure when the roofing shake is installed on a roof and an opposite top surface. A first body portion is disposed proximate the first end. The top surface of the first body portion is configured to be at least partially covered by one or more other roofing shakes. A second body portion is disposed proximate the second end. One or more reinforcement members are embedded within the roofing shake and within the second body portion, the one or more reinforcement members positioned adjacent an outer perimeter edge of the second body portion.

A system includes a photovoltaic module having photovoltaic cells, each having a width, and a roofing shingle having an exposure zone and a headlap zone. A plurality of slots extends from the exposure zone to the headlap zone and define tooth portions. A first one of the tooth portions has a first side defined by a first slot and a second side defined by a second slot adjacent to the first slot. The first tooth portion has a first width that is the photovoltaic cell width multiplied by a first positive integer. A second tooth portion has a first side defined by a third slot and a second side defined by a fourth slot adjacent to the third slot. The second tooth portion has a second width that is the photovoltaic cell width multiplied by a second positive integer different than the first positive integer.

A system includes a plurality of photovoltaic modules, each having a mat with an edge and a spacer with an edge, the edge of the mat being attached to the edge of the spacer. The spacer includes a plurality of support members and a solar module mounted to the support members. Each of the support members includes a ledge. The solar module and the ledge form a space therebetween. The space is sized and shaped to receive an edge of a solar module of another of the photovoltaic modules. The spacer of one of the photovoltaic modules overlays the mat of another of the photovoltaic modules.

This invention, in embodiments, relates to a roofing system comprising (a) a roofing substrate having a roofing surface, (b) a first roofing tile overlying the roofing surface, the first roofing tile having a front surface, a back surface, a top edge, and a bottom edge, and (c) a second roofing tile overlying the first roofing tile, the second roofing tile having a front surface, a back surface, a top edge, and a bottom edge. At least one sealant line is applied to (i) the back surface of the second roofing tile in an area that overlays the first roofing tile, (ii) the front surface of the first roofing tile in an area in which the second roofing tile overlays the first roofing tile, or (iii) both (i) and (ii). The at least one sealant line is configured to adhere the second roofing tile to the first roofing tile.
