Abstract: A roofing ventilation system for a metal building. The system includes a compressible seal between a corrugated sheet metal roof and a roof vent of the system. Further, the present invention utilizes an insulating block having venting capability in order to allow moisture and hot air in the roofing system to escape, thereby reducing corrosion of the metal roof and deterioration of the insulating ability of the insulation material. In one embodiment, the system includes a shield between the insulating vent block and insulation material, such that insulation adjacent a compressed area of material does not obstruct the air passages of the insulating block. In one embodiment of the present invention, the compressible seal is a sealing strip that conforms to the profile and shape of the corrugated roof. The sealing strip is formed from an open-celled foam material and has a plurality of slits to provide an environmental barrier across the length of the corrugated roof.

Abstract: A ridge vent assembly extends along a roof ridge of a building. One embodiment has corrugated plies defining small diameter passages that communicate a vent opening cut along the ridge of the roof with ambient atmosphere. A moveable valve member extends along the outer edge of the vent parts and includes a lift spacer to keep the valve member spaced from the roof when in an inactive position. When wind speed increases above a predetermined wind speed, the movable member moves into a position adjoining the edge of the vent parts and the bubble is compressed against the upper edge of the corresponding vent part, thereby preventing entry of wind driven moisture and snow into the passages and into the building structure through the vent opening. Accordingly, the moveable valve member acts as a weatherstripping material for the vent. A similar flexible member is usable to weatherstrip windows, doors, and other building openings.

Abstract: A ridge vent assembly extends along the ridge of the roof of a building structure and is provided with multiple plies of corrugated material. The corrugations of the plies define small diameter passages that communicate a vent opening cut along the ridge of the roof with ambient atmosphere. A flexible member consisting of a strip of cloth material extends along the outer edge of the vent parts. The strip of material terminates into a flexible bubble. When wind speed increases above a predetermined wind speed, the movable member moves into a position adjoining the edge of the vent parts and the bubble is compressed against the upper edge of the corresponding vent part, thereby preventing entry of wind driven moisture and snow into the passages and into the building structure through the vent opening. Accordingly, the cloth strip and bubble act as a weatherstripping material for the vent.

Abstract: Ventilating material for covering a vent opening in a roof consists of multiple panels that interconnect with each other to condense the venting material for transport by permitting it to be folded into multiple layers. A fastening band extends around all but one of the panels and a second fastening band extends around all of the panels to thereby hold the panels together for transport. After the bundle is placed on the roof of a building structure, the second fastener is released to release the first panel, while the remaining panels remain bundled together by the other fastener. The method of creasing and folding the materials to permit multiple ply corrugated material to be folded to form the bundle of venting material is also disclosed. The folding process may also be used, according to still another aspect of the invention, to make a transport container of multiple ply corrugated material.

Abstract: A ventilating device for a roof having a vent opening includes a cover for a vent opening in the roof. The cover defines vent passages for communicating the vent opening to ambient atmosphere. A moveable member mounted adjacent to the passages is moveable from an open or inactive position permitting communication through the passages to an active or closed position in which the moveable member closes the passage to restrain entry of wind driven rain and or snow into the passages. The moveable members are returned to their inactive or open position by the resiliency of the material from which the moveable members are made and/or by the force of gravity.

Abstract: A ventilating cap for the roof includes a cover which is supported over a vent opening extending along the ridge of the roof by a first pair of coil springs supporting one side of the cap and a second pair of coil springs supporting the other side of the cap. Optional foam rubber blocks may be installed between the pairs of coils and also extend longitudinally along the roof to restrict entry of wind blown moisture from entering the vent opening. In another embodiment of the invention, nonwoven batts are retained by the springs to restrain entry of moisture into the vent opening. In still another embodiment of the invention, a deflectable baffle is moved from an inactive position laying on the roof to an active position closing off passages between the coils to wind blown moisture in response to wind velocity above a predetermined level.

Abstract: A ventilating cap for the ridge of a roof includes a pair of vent parts located on opposite sides of a vent opening cut along ridge board of the roof.
