A roof ridge and hip ridge vent system for contoured roofs which include a vent slot located through the roof structure. A contoured roofing material forms the roof surface. Vent strips are provided on the roof surface that extend on each side of the vent slot. The vent strip is comprised of synthetic fibers that are randomly aligned into an open web by an air flow and then joined by a phenolic or latex binder to form an air permeable mesh material having a generally uniform thickness, a density of about 0.08 to 0.1 grams per cubic centimeter (1.3 to 1.6 grams per cubic inch), and a crush recovery of at least 80%. A first longitudinally extending groove extends from the bottom surface about 40% to 60% of a height of the vent strip and is located a distance of at least about 1 inch from a downslope side.

A corrugated plate assembly includes at least two corrugated plates each having a crest portion. The crest portion is asymmetric and includes first and second arcuate ends, two longitudinal lateral sides connected between the first and second arcuate ends and two indentations indented from the first and second arcuate ends. The second arcuate ends of the corrugated plates are interconnected in such a manner that the indentations of the second arcuate ends are intersected each other and that the second arcuate ends overlap with each other. Ventilation gaps are formed between overlapping parts of the second arcuate ends.

Systems and methods for collecting solar energy and ambient heat are provided. A roof panel includes a metal sheet disposed about an upper end of the roof panel. Heat insulation is disposed below the metal sheet. At least one hot air duct and at least one cold air duct are each formed parallel to a rafter direction and in the plane of the roof panel. Each hot air duct is exposed to a surface of the metal sheet, and each cold air duct is encompassed by the heat insulation. A medium collectively fills the air ducts. A lower air reversing chamber is formed at a lower end portion of the roof panel, and an upper air reversing chamber is formed at an upper end portion of the roof panel. A cooling device is disposed in the upper air reversing chamber.

This invention is an envelope-structure interface, enabling the use of exterior insulation and pressure-equalized cladding with a post-frame structure. The present invention includes the following interface details: a continuous roof-to-wall water, vapor, and air impermeable weather barrier that is fully adhered to sheathing exterior of framing, girts, and purlins; continuous roof-to-wall insulation exterior of weather barrier that is mechanically fastened back to the post-frame structure; and removal of the requirement for an interior finish material in a conditioned post-frame building. The invention brings superior envelope performance to the structural and material efficiency, rapid rate of construction, and affordability of post-frame techniques.

A rafter vent system suitable for valley roof or hip roof construction, the system having at least one rafter bypass channel member in fluid communication with rafter vent members positioned between adjacent hip or valley rafters, the rafter bypass channel member providing a bypass channel for passage of ventilating air along a hip or valley rafter, such that a passageway is created extending between eave vents and ridge vents.

A corrugated plate assembly includes at least two corrugated plates each having a crest portion. The crest portion is asymmetric and includes first and second arcuate ends, two longitudinal lateral sides connected between the first and second arcuate ends and two indentations indented from the first and second arcuate ends. The second arcuate ends of the corrugated plates are interconnected in such a manner that the indentations of the second arcuate ends are intersected each other and that the second arcuate ends overlap with each other. Ventilation gaps are formed between overlapping parts of the second arcuate ends.

A ventilating and heat dissipating assembly for a roof includes hollow bricks, first corrugated plates and second corrugate plates. Each first corrugated plate spans a gap between two pairs of the hollow bricks that are spaced apart along intersecting first and second directions. Each second corrugated plate spans a gap formed between two of the hollow bricks spaced apart in the first direction and a gap between two of the first corrugated plates spaced apart in the second direction.

A hollow brick includes a bottom wall, two side walls projecting from the bottom wall, a plurality of intermediate walls projecting from the bottom wall between the side walls, and a top wall opposite to the bottom wall and connecting the side walls and the intermediate walls. A plurality of ventilation holes is bounded by the bottom wall, the side walls, the intermediate walls and the top wall. Each ventilation hole has two ventilation open ends opposite to each other along the transverse sides of the bottom wall. Two outer holding ribs projects respectively from outer surfaces of the side walls in opposite outward directions.

A hollow brick includes a bottom wall, two side walls projecting from the bottom wall, a plurality of intermediate walls projecting from the bottom wall between the side walls, a top wall opposite to the bottom wall and connecting the side walls and the intermediate walls, and a plurality of ventilation holes bounded by the bottom wall, the side walls, the intermediate walls and the top wall. The bottom wall has a plurality of foot portions projecting downwardly and spaced apart from each other. A bottom groove is formed between two adjacent ones of the foot portions.

A converted reverse ballasted roof system is provided including a structural roof beam. Insulation is positioned upwardly adjacent the structural roof beam, and a first waterproofing membrane is arranged upwardly adjacent the first waterproofing membrane. A weighted cover board is disposed upwardly adjacent the first waterproofing membrane and a second waterproofing membrane is installed upwardly adjacent the weighted cover board. The first water proofing membrane and the second waterproofing membrane substantially seal the weighted cover board.
