A shingle assembly for installation on a roof structure is provided. The shingle assembly can include an insulative substrate, a surface sheet coupled to and extending across a substantial portion of the insulative substrate, and a hook-and-loop fastening system comprising a hook portion and a loop portion. The hook portion or the loop portion can be coupled to and extend along the insulative substrate adjacent the surface sheet. The other of the hook portion or the loop portion can be coupled to and extend along the surface sheet. The hook portion can be configured to mate with a loop portion of a first adjoining shingle assembly and the loop portion can be configured to mate with a hook portion of a second adjoining shingle assembly.

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.

In at least some implementations, a foam product includes 50% to 75% by weight thermoset, between 1% and 10% by weight colorant, between 1% and 3% by weight blowing agent, and one or more fire retardant additives embedded in the foam. Such a foam product may be used, for example, as a board, tile, shingle, shake, or other component for an interior or exterior portion of a residential or commercial structure. In the examples of shingles, shakes, tiles and the like, the foam product may be used on a roof or any other desired portion of a structure, and it may be used for decoration, protection and/or insulation of the structure.

A panel for attachment to a mounting surface includes a plurality of raised faces formed and extending between an upper edge and a lower edge of the panel, and a plurality of recessed keyways defined between each of the raised faces. The panel may have a recessed base at the lower edge of the keyways defining a fold lip adjacent the mounting surface, and a full base formed at the lower edge of the raised faces and extending beyond the recessed base.

The panel may have a recessed base at the lower edge of the keyways defining a fold lip adjacent the mounting surface, and a full base formed at the lower edge of the raised faces and extending beyond the recessed base. The fold lip provides a reaction point for an under lap extending from the lower edge toward the upper edge. The panel may include a lock flange formed at the upper edge. The lock flange defines a lock slot between layers of the panel, and closes the lock slot to substantially zero depth at a first touch point and a second touch point.
