A roofing, cladding, or siding apparatus comprises a roofing, cladding, or siding module and at least one clip. The module comprises an underlapping region and an exposed region. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent overlapping module when installed on a building surface. A projection extends from the exposed region to provide a bearing surface facing the under surface of the exposed region. The clip or clips is attachable to the underlapping region to provide a tongue adapted to be received between the bearing surface and the under surface of the exposed region of an adjacent overlapping module when installed on a building surface.

A system includes a plurality of photovoltaic shingles installed on a roof deck, each of the shingles having a first layer including a head lap portion, and a second layer including at least one solar cell. A first photovoltaic shingle overlays at least a part of the head lap portion of a second photovoltaic shingle. The system includes at least one wireway installed proximate to a first end of at least the first photovoltaic shingle.

A roof mourned diverting device for diverting a direction of flow of gas from a roof-penetrating pipe is provided. The roof-penetrating pipe has a central axis. The device includes a diverter having a lower opening and an upper opening, the upper opening having a central axis; and a seal having a seal opening, the seal opening being configured to contact an outer surface of the roof-penetrating pipe and form a gas-tight seal with the roof-penetrating pipe. In an assembled state of the device, any of the gas that enters the diverter can only exit the diverter through the upper opening or through the roof-penetrating pipe, and the diverter is installable in multiple different positions, each of the different positions having a different included angle between the central axis of the upper opening and the central axis of the roof-penetrating pipe.

A hollow brick includes a bottom wall, two side walls, two intermediate walls, and a top wall. The top wall defines three arched top boundary surfaces of three ventilation holes bounded by the bottom wall, the side walls, the intermediate walls and the top wall. Two supports, each of which supports a first corrugated plate, project from the side walls. Two inner holding ribs are in two ventilation holes respectively proximal to the side walls and lie below the arched top boundary surfaces. A middle one of the arched top boundary surfaces abuts and presses a curved middle portion of a second corrugated plate, and the inner holding ribs respectively lift lateral portions of the second corrugated plate.

It is described herein a roofing insulation structure. The roofing insulation structure may comprise a first exterior surface and a second exterior surface opposite the first exterior surface. The first exterior surface may comprise a channeled profile having a plurality of channels. Each channel of the plurality of channels may have a depth of at least 1 mm, a width of at least 0.15 mm, and a ratio of depth to width in a range of between 1.01:1 and 7:1. It is also described herein a roofing insulation system comprising a plurality of the roofing insulation structures. It is also disclosed herein a method of manufacturing the roofing insulation structures. It is also disclosed herein a method of installing the roofing insulation system.

A roof vent for a contoured metal surface. The roof vent includes a base or foot having one or more recessed channels that extend between opposing edges of the foot. The recessed channels are sized and shaped to receive correspondingly shaped ridges of the contoured metal roof surface.

A roof vent and a roof structure are described. A roof vent can include a baffle with a cross-section where a first portion extends upward from a bottom plate and a second portion extends from the first portion to define a space between the bottom plate and the second portion. A roof structure may or may not have a roof deck, and comprises a plurality of roof cover elements with a radiant barrier layer underneath the top surfaces of at least some of the roof cover elements. In another embodiment, a roof structure may comprise more sheathing layer vent members than roof cover layer vent members. In yet another embodiment, a roof structure may comprise a layer of roof tiles with at least one vent member, the vent member comprising lateral end portions of a base member with a non-planar profile to engage a similar profile of an adjacent roof cover element.

A system includes a plurality of photovoltaic shingles installed on a roof deck, each of the shingles having a first layer including a head lap portion, and a second layer including at least one solar cell. A first photovoltaic shingle overlays at least a part of the head lap portion of a second photovoltaic shingle. The system includes at least one wireway installed proximate to a first end of at least the first photovoltaic shingle.

An off-ridge roof ventilation device for placing on an opening of a roof deck. The ventilation device comprises an elongated main hood with a curved shape. The right end of the main hood is closed by a right-side panel, and the left end of the main hood is closed by a left-side panel. The main hood comprises a perforated top face and a venting opening on a bottom face. A throat panel is placed on the bottom face of the main hood in a manner to reduce the venting opening. A perforated interior panel is placed between the top face of the main hood and the throat panel to eliminate wind driven rain and/or snow even in high wind situations. The perforations are preferably designed as mini-louvers, wherein the mini-louvers of the main hood and the mini-louvers of the throat panel comprise the same shape and count the same number.
