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 shingle patch for repairing damaged asphalt shingles including a base member having a notched portion or a thin sheet of material associated with one end thereof for sliding under the existing shingle located immediately above the damaged shingle, a sealant covering at least a portion of the notched portion or thin sheet of material and the bottom surface of the base member for attaching the base member to the damaged shingle, and color granules associated with at least a portion of the top surface of the base member. A nail may be embedded in the base member to further secure the shingle patch to a damaged shingle. An additional two-piece shingle patch is provided wherein the base member is further separated into two separate parts, an upper base member and a lower base member, the lower base member including the notched portion or a thin sheet of material.

Hip and ridge shingles may be single layer or laminated. One hip and ridge shingle has a base layer and a dimensional layer affixed to the base layer by an adhesive line that extends in the machine direction and along the width of the base and the dimensional layers. The adhesive line is disposed on only one lateral side of the base layer and dimensional layers to allow movement of another lateral side of the dimensional layer relative to the base layer. Another laminated hip and ridge shingle includes a base layer and a dimensional layer affixed to the base layer by an adhesive line that extends in the machine direction and along the width of the base and the dimensional layers. Sealant that comprises at least two parallel lines of sealant material that extend in the machine direction of the base and dimensional layers is disposed on a bottom surface of the base layer for adhering the hip and ridge shingle to an underlying hip and ridge shingle. Another hip and ridge shingle, which may be single layer or laminated, includes a granule coated asphalt substrate, sealant on the substrate, and release tape on the substrate. The sealant comprises at least two parallel lines of sealant material that extend in a direction of a width of the substrate for adhering the hip and ridge shingle to an underlying hip and ridge shingle. The release tape is disposed on a bottom of the substrate and is alignable with the at least two parallel lines of sealant when two of the hip and ridge shingles are stacked to prevent the two hip and ridge shingles from sticking together.

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.

A finishing shingle includes a sheet having a front surface and a rear surface. The front surface is configured to resemble the shingle installed on a roof with which the finishing shingle will be used. The sheet further includes a central, frangible seam longitudinally extending from one side edge to an opposing side edge that allows a worker to easily separate the sheet into two equal finishing shingles that are substantially half the size of the roof shingle. Nail targets positioned on the top surface provide a template for a worker to nail the finishing shingle to the underlying flashing. Circular sealant patches on the rear surface are aligned with the nail targets to form a watertight seal around the nail and flashing.

A system includes a plurality of roofing shingles installed on a roof deck. Each of the roofing shingles includes first and second ends, first and second edges, a head lap, a reveal portion, a first side lap at the first end, and a second side lap at the second end. The second side lap includes a first surface, which has an adhesive. The first side lap of a first one of the roofing shingles overlays and is attached to the second side lap of a second one of the roofing shingles to form a sealed portion between the head lap of the first one of the roofing shingles and the head lap of the second one of the roofing shingles.

A multi-layer cap shingle for installation along a ridge, hip, or rake of a roof includes a forward exposure area and a rear headlap area. The multi-layer cap shingle includes at least two layers of shingle material, a top layer and a bottom layer each having opposed edges. The layers are bonded together with patches of lamination adhesive adjacent their opposed edges. The bottom layer is configured with a deformation-absorbing mechanism such as a pair of slots extending from a forward edge reawardly inboard of the lamination adhesive patches. When the multi-layer cap shingle is bent over a roof ridge, the slots of the bottom layer of shingle material narrow in width to account for the fact that the bottom layer must bend around an arc of slightly smaller radius than the top layer of shingle material. As a result, the opposed edges of the bottom and top layers of shingle material remain aligned and both edges of the top layer are laminated to the bottom layer to increase wind lift resistance of the installed multi-layer cap shingle.
