A roofing sample display having a plurality of panels or sections that fold over one another. The roofing sample display has a top primary panel having printed matter on both an inner and an outer side of the panel, a bottom primary panel having a plurality of layers of shingle samples attached to an inner side with a rubber pressure-sensitive adhesive and printed matter on an outer side, a secondary internal panel having printed matter on both an inner and an outer side, and two thin end panels to accommodate the thickness of the plurality of layers of shingle samples and thereby allow the roofing sample board to fold neatly.

Load support structures for mounting a load atop a raised rib metal panel roof make use of relatively small, inexpensive, and easy-to-make adapter plugs as interfaces between the raised ribs and one or more component pieces or members of the load support structure, such as an upper diverter or a lower closure member. The adapter plug has an inner surface and an outer surface, the inner surface having an inner profile substantially matching or conforming to some or all of the profile of a particular style of rib profile. The outer surface of the adapter plug has a standardized shape, some or all of which is made to conform to an upper diverter, lower closure, and/or other component member of the load support structure.

An exemplary shingle includes at least one coated shingle sheet defining a headlap portion and a tab portion each having opposed upper and lower surfaces. A first line of adhesive is adhered to one of the upper surface of the headlap portion and the lower surface of the tab portion, and includes a first thermally activated adhesive material. A second line of adhesive is adhered to one of the upper surface of the headlap portion and the lower surface of the tab portion, and includes a second thermally activated adhesive material having a minimum activation temperature less than a minimum activation temperature of the first thermally activated adhesive material.

A laminated roofing shingle is disclosed comprising a posterior layer with tabs and an anterior layer with tabs spaced apart by openings, wherein each posterior tab is partially covered by a corresponding anterior tab, wherein at least one anterior tab has a first anterior tab breadth and at least another anterior tab has a second anterior tab breadth, and wherein at least one anterior opening has a first anterior opening breadth that is about equal to the second anterior tab breadth and wherein at least another anterior opening has a second anterior opening breadth that is about equal to the first anterior tab breadth. Also disclosed is a roofing system comprising a plurality of courses of the shingle.

A lightweight roofing shingle comprising a saturated mat having an exposed side and an unexposed side wherein a fabric reinforcing layer substantially replaces the bottom asphalt coating and the backing aggregate on the unexposed side of a conventional shingle. The lightweight shingle will have a top asphalt layer applied to the exposed side of the mat and a layer of granular material applied to the top asphalt layer opposite the mat per conventional construction, and the fabric reinforcing layer is adhered directly to the unexposed side of the saturated mat. In one embodiment, the fabric reinforcing layer covers an entire area of the unexposed side of the saturated mat. The reinforcing layer may preferably be a nonwoven fabric made from PET or polypropylene. The lightweight roofing shingle may also include a release tape layer applied to the reinforcing layer opposite the saturated mat.
