A moulded article is provided with a presentation side surface and a non-presentation side surface, where the presentation side surface provides for a pre-determined surface decoration, and the non-presentation side surface is an opposing face to the presentation side surface. The non-presentation side surface includes one or more structure(s), where the one or more structure(s) are arranged or positioned to provide or contribute the pre-determined surface decoration of the presentation side surface.

A roofing system including a plurality of photovoltaic modules installed on a roof deck, where each of the photovoltaic modules includes at least one solar cell, and a plurality of metal roofing shingles installed on the roof deck adjacent the plurality of photovoltaic modules, where the plurality of metal roofing shingles includes at least a first metal roofing shingle and a second metal roofing shingle, where each of the metal roofing shingles includes a first layer that includes a metal material, and a second layer that includes a polymer material, where the second layer includes a nail zone with a plurality of fasteners extending therethrough, fastening the metal roofing shingle to the roof deck, where the second layer is between the roof deck and the first layer.

A system includes a plurality of photovoltaic modules, a plurality of step flaps, and a plurality of roofing shingles installed on a roof deck. Each of the step flaps includes a first layer and a second layer, with the first layer overlaying a portion of the second layer, and the first layer attached to at least a portion of an overlapping portion of the second layer within an attachment area. An end of each of the plurality of photovoltaic modules overlays a portion of a corresponding one of the plurality of step flaps. An end of a first roofing shingle overlays a first step flap. The second layer of a second step flap vertically above the first step flap overlays a headlap portion of the first roofing shingle.

A measuring apparatus for marking a cut line on roofing panels having a raised rib configuration is formed with an elongated base member and a cross member pivotally connected to the proximal end of the base member permitting rotation of the cross member relative to the base member. The cross member includes a protractor section, including indicia indicative of the angle of rotation of the cross member, to define the desired angle of a cut line. The base member includes at least two seating members removably retained within the C-channel shape of the base member to provide a stable seating of the base member on the roofing panel rib. The seating members can be interchanged to match the rib configuration. A locking mechanism secures the rotated position of the cross member to enable the measurement of the desired and then handed off to mark the cut line.
