The present disclosure relates generally to roofing systems, for example, suitable for covering the roof of a house or other building. The present disclosure relates more particularly to a roofing system that includes a plurality of riser blocks disposed on a support surface. The riser blocks include a group that is aligned in a row. A batten extends along the row and is supported by the group of riser blocks. The batten includes a first clip portion. A group of roofing panels is disposed along the row and is supported by the batten. Further, each of the roofing panels of the group includes a front surface, a rear surface, and a second clip portion extending from the rear surface. The second clip portion is configured to engage the first clip portion of the batten so as to secure the roofing panels to the batten.

A tile system comprises at least two tiles and at least one elongate support. Each tile is generally rectangular in shape and has a first edge, and a second edge, the second edge being generally opposite the first edge. Each elongate support has an attachment portion and a support portion. Proximate the first edge each tile is provided with a groove, the groove being configured to receive the support portion of one of the elongate supports and a portion of an adjacent tile proximate its second edge.

One illustrative embodiment of a tile & support structure may be configured to secure the position of a tile in a generally vertical configuration, such as the riser of a step, as a border around a portion of a deck, a building and/or wall façade, ventilated façade, interior or exterior wall covering, or other generally vertical surface. The support structure may be formed with a spine having at least one rail extending outward from a distal end thereof. The spine and rail(s) may be configured to secure one or more tiles, which tiles may be formed with a groove on at least one edge thereof, and wherein one or more rails may be positioned within the groove.

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 section of a roof covering system, such as a shingle, having a flat base with planar top surface; and a plurality of fins disposed on the planar top surface at an essentially orthogonal angle to the planar top surfaces, forming a plurality of valleys between the fins, thereby forming a plurality of protrusions and recesses to damage, disintegrate and redirect hailstones which are incident upon the portion of the roof covering system.

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.

Roofing shingles are disclosed that are capable of being attached to a roof deck, underlayment, and/or other roofing shingles and that require few mechanical fasteners to remain attached to the roof. The roofing shingles are formed with a first layer and a second layer of shingle materials that are laminated together, and with the first and second layers further being mechanically attached with indentations in the first and second layers at spaced locations along and across the roofing shingles. A roofing system comprising a plurality of courses of the roofing shingles is also disclosed.
