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 rearwardly 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.

Shingle blanks including a first fold region, a second fold region, a third region, a lower edge and an upper edge are provided. The shingle blank has a length. The first and second fold regions extend substantially across the length of the shingle blank. The second fold region is positioned between the first and third fold regions. A first perforation line is positioned between the second and third fold regions. A second perforation line is positioned between the first and second fold regions. A reinforcement material is positioned over the first perforation line and configured to reinforce the first perforation line. The reinforcement material includes apertures configured to allow an asphalt coating to bleed through the reinforcement material. The first and second perforation lines facilitate folding of the first and second fold regions on top of the third region to form a three layered stack.

A sealing gasket (4) for use between flashing members (31,32) is disclosed. It comprises a compressible sealing section and an attachment section comprising at least two legs configured for engagement with a flashing member, both sections extending over substantially the entire length of the sealing gasket. The at least two legs of the attachment section project from a base section of the attachment section so that a first recess and a second recess extending in parallel are defined, said first and second recesses being configured for engagement with a flange, ridge, or leg on a flashing member. The invention further relates to a flashing arrangement and to a method of sealing a gap between flashing members for a roof window.

Ridge vents and deck covers are disclosed that have a fibrous mesh mat and a moisture barrier. The mesh mat may be contoured to define a variety of structures and may have regions of relatively higher fiber density and regions of relatively lower fiber density. Solar cells may be exposed on the ridge vents to collect solar energy when the vents are exposed to sunlight.

A microbial inhibiting system for angled asphalt roofs. The system includes copper-based strips along the ridge of the roof, wherein the proximal edges of the copper-based strips are operatively associated between a ridge vent and a portion of the upper roof. A distal end of the copper-based strips may provide windshear bends to keep the whole system in place during high winds. Once installed onto an asphalt roof, the present invention is adapted so that rainwater is directed over the copper-base members of the system, causing a chemical reaction therewith, wherein the resulting chemical will wash away along the roofing membrane, removing any mold, algae, and moss as the chemically infused rainwater rolls down the roof.

A ridge or hip member for a roof comprising a substantially flexible zone and a substantially rigid zone on each side of the flexible zone. The flexible zone adapted to allow the member to be bent by an installer by hand to conform the member to the ridge or hip of a roof, with the flexible zone located along a ridge or hip line of the roof. Each rigid zone being located on each side of the ridge or hip line.

In one aspect there is disclosed a waterproofing building product (10) for use in waterproofing a joint (12) between a first and second roofing panel (14, 16). The waterproofing building product (10) includes an overlapping section (18) operatively adapted to overlap a portion of the first roofing panel (14) and an underlapping section (20) operatively adapted to underlap a portion of the second roofing panel (16). The waterproofing building product (10) further includes a transition section (22) located between the overlapping section (18) and the underlapping section (20) and connecting the overlapping section (18) with the underlapping section (20).

A roofing system including a cap shingle and a method of producing a cap shingle are disclosed. In one embodiment, the cap shingle is formed with a continuous or discontinuous self-sealing adhesive that is applied along a ridgeline direction and can provide high wind resistance, without the use of hand-sealed adhesive application. In an embodiment of the method, one or more layers of a shingle material can be oriented in a machine direction with the self-sealing adhesive applied adjacent side edges of the shingle material to form the cap shingles having self-seal strips and configured to bend in the machine direction for installation of the cap shingles along a ridge of a roof.
