A spacer has an elongated body having a first end and a second end that are spaced along a longitudinal axis. The elongated body has a first side and an opposed second side that are spaced along a transverse axis that is perpendicular to the longitudinal axis and a third side and an opposed fourth side that are spaced along a thickness axis that is perpendicular to the longitudinal axis and the transverse axis. At least one channel extends into the elongated body from the third side of the elongated body and toward the fourth side of the elongated body. The at least one channel extends along the transverse axis from the first side to the second side of the elongated body. Each channel has opposed ends each having a width, and a neck between the opposed ends. The neck is narrower than the width of each of the opposed ends.

The present disclosure concerns specially patterned zinc sheets for coverage and protection of building roofs and facades. A recurrent problem linked with the use of zinc sheets in building applications is the development of white rust. As the complete avoidance of white rust is difficult to achieve, additional means to reduce its impact are most welcome. It is now proposed to limit the visibility of white rust by providing a camouflaging pattern on the surface of the zinc. The invention more specifically concerns an unweathered rolled zinc alloy sheet with at least one patterned face having an optical reflectivity that varies from region to region, characterized in that said regions are of a pseudo-random shape, having characteristic dimensions in the range of 0.1 mm to 10 cm; and in that the optical reflectivity, when measured across the sheet in any arbitrary direction, presents a specular reflectivity RMS deviation of more than 3 GU and/or a diffuse reflectivity RMS deviation of more than 0.2. A laser-aided imprinting process is disclosed to generate suitable camouflage patterns on the zinc.

A snow brake anchoring system for an inclined roof having a plurality generally T-shaped standing seams that extend upwardly from the inclined roof surface, the snow brake anchoring system having a two-part anchor body defining a width adjustable elongated and generally rectilinear channel. The first half of the body caring an elongated convexly shaped rotation protuberance on an interior surface, and the second half of the body defines an elongated concavely shaped notch on an interior surface, and the rotation protuberance is at least partially carried within the concavely shaped notch allowing the two body halves to move relative to one another to adjust the width dimension of the elongated generally rectilinear channel. Gripping protuberances are carried at a bottom portion of each edge of the channel to frictionally engage with the T-shaped standing seam, and a plurality of fasteners releasably interconnect the body halves to one another.

A roofing system having at least one underlayment layer; at least two nail fasteners attached to the at least one underlayment layer and into the roof deck, wherein the head of each of the nail fasteners is above the at underlayment layer and the shaft is driven through the underlayment layer and into the roof deck; at least one bead of adhesive applied above the underlayment layer; and at least one metal roofing panels placed on the at least one bead of adhesive applied above the underlayment layer, wherein the at least one metal roofing panels are above the at least two nail fasteners and the at least two nail fasteners do not penetrate the at least one metal roofing panels.

A Wind uplift strap for securing a coverage structure. The Wind uplift strap including one or more metal strips having a thickness between 0.50 mm and 1.1 mm, substantially equal to that of the coverage structure, and a width between approximately 15 mm and 50 mm, depending on the load to be supported. The Wind uplift strap having a slightly angled fold in more than 90, forming a flap at one of its ends. The Wind uplift strap further comprising a main body, a flap, a hole for fixing the flap, a fold line of the flap, and a hole at an end of the main body that is opposite the flap.

A spacer designed to be inserted between the roofing panel clip and the sheathing is provided. The spacer has a configuration of openings and slots on the spacer to allow it to be used with a wide variety of panel clips. The opening for the fastener, the outer rim, and the walls of the spacer are designed to seal against the sheathing and provide tiers of protection to prevent water from contacting the fasteners. The spacers are designed to have lips, grooves, and recessed areas that coincide with the walls to accommodate stacking to allow for different channel heights without having to stock multiple spacer sizes. Also, the preferred embodiment of the spacer is rounded to prevent water from collecting along the edges of the spacer and instead flow down the slope of the roof. Finally, the spacer is specifically designed to have one spacer per panel clip.

The present application provides a roofing assembly (300). The roofing assembly (300) comprises: a support frame (310, 320); a window panel (350) supported on the support frame; a roof covering (319, 364) having an inner surface facing the support frame (310, 320) and extending over the support frame (310, 320) to a boundary of the window panel (350); and a sealing adaptor (360) comprising a sealing portion (430) having a sealing surface (432) for forming a seal against the window panel (350), and a retaining portion (410) defining a retaining recess (420) formed to retain an end of the roof covering (319, 364) therein. The retaining portion (410) comprises a lip region (422) for contacting the inner surface of the roof covering (319, 364) when the end of the roof covering (319, 364) is received in the retaining recess (420). The retaining recess (420) is provided between the lip region (422) and the sealing surface (432).
