A roof drainage system designed to be in-line with the rain-screen-type exterior wall finish assembly to discharge run-off water to a drainage location, including a gutter assembly recessed into the roof edge structure connected to a downspout assembly that is recessed into the exterior finish material outboard of the rigid insulation and weather barrier that allows for ease of maintenance, clean out, and replacement; with a day-lit or sub-grade tie-in type outlet; that also visually blends into the faade.

A gutter diverter is disclosed may include providing a base having a generally triangular shaped planar section having a first leg, a second leg, and a third leg positioned at a periphery of the generally triangular shaped planar section. In addition, the gutter diverter may include forming a first attachment tab positioned on the first leg of the base and projecting orthogonally downwardly from the base. The gutter diverter may include forming a second attachment tab positioned on the second leg of the base and projecting orthogonally downwardly from the base. Moreover, the gutter diverter may include forming a diverter plate positioned on the third leg of the base and projecting orthogonally upwardly from the base.

There is provided: a novel roof panel that is easy to manufacture, is durable, and is capable of completely preventing rainwater ingress and easily draining rainwater; a roof using the roof panel; and a three-dimensional structure with the roof. A precast concrete roof panel 10 includes on its upper surface 14 an inclined main portion 16 that is inclined downward toward an edge.

A roof panel includes a planar body having top and bottom edges, with a downturn edge extending therebetween, and an opposing channel edge. The downturn edge overlays a channel edge of an adjacent panel. The bottom edge overlays a top edge of another adjacent panel. A plurality of courses extends between the channel and downturn edges. Each course includes a nesting ridge to receive the downturn edge of an adjacent panel and to position a top surface of the panel flush with adjacent panels. Surface channels and contoured ridges are defined within each course. A drain aperture of the drip edge aligns with an adjacent channel edge to direct material through the drain aperture and onto adjacent panels. A gable member engages an edge when the panel has one or fewer laterally adjacent panels, wherein the gable member is flush with the adjacent planar body.

A photovoltaic (PV) module mounting system including a rail having a base wall and opposed first and second sidewalls extending outwardly therefrom. The first and the second sidewalls each have a flange extending outwardly therefrom. The flanges form a mounting surface adapted to support a PV module. The first and the second sidewalls define therebetween an open channel. A wire support is disposed between the first and second sidewalls and is adapted to support wires extending through the channel at a distance spaced from the base wall. The wire support divides the channel into a wireway and a water channeling portion. The wire support includes an opening therein to permit fluid communication between the wireway and the water channeling portion.

A gable member engages an edge when the panel has one or fewer laterally adjacent panels, wherein the gable member is flush with the adjacent planar body.

A building includes an outer wall, a roof arranged so as to be orthogonal to the outer wall and inclined with respect to the ground, and a flashing arranged at a boundary between the roof and the outer wall. The flashing includes an attachment configured to extend along the outer wall, a guide connected to the attachment and arranged above the roof, and a water draining portion arranged so as to intersect the attachment and the guide.

Embodiments of the present technology may encompass drip gutters. The drip gutters may include a vertical member. The drip gutters may include a horizontal member extending laterally outward from the vertical member. At least a portion of the vertical member may extend upward above the horizontal member. The drip gutters may include a vertical lip extending upward from a surface of the horizonal member and laterally spaced apart from the vertical member such that an open-topped drainage channel is formed between the vertical member, the horizontal member, and the vertical lip.

A coating cover with a metal structure for roofs of buildings comprises a plurality of slabs of substantially quadrilateral shape, each of which is provided with lateral edges that are parallel and opposite to one another for mutual connection between adjacent slabs in a longitudinal direction and for formation of a joint positioned between each of the adjacent slabs. The lateral edges comprise a first set of folds at least partially symmetrical on the two edges. The lateral edges also include a second set of folds on at least one of the lateral edges, and a third set of folds on at least one other lateral edge. The lateral edges comprise at least one curvature at one of the first set of folds placed horizontal and parallel to the installation base. The cover also has at least one fixing bracket that is configured to join the lateral edges.

A modular roof structure comprises a frame to which an array of solar panels are attachable. The frame comprises purlins at a periphery of the roof structure, the purlins being configured to receive edges of the solar panels thereat, and rafters arranged between the purlins in a configuration to receive opposing edges of adjacent solar panels thereat, the rafters comprising gutters for collecting water that runs off the solar panels and directing the collected water to a water outlet.
