Abstract: A roofing system has individual roofing panels that include a metal outer skin surrounding an insulation layer, a factory-applied protective membrane of polyisobutylene, and interlocking components for providing a rigid roof that is self-supporting and requires no sub-deck. The panels with pre-applied protective membranes are adapted to be factory-shipped to a job site so that assembly and sealing can be achieved in a one-step process.

Abstract: An assemblage of sheet metal roof covering pieces is utilized in a novel process to recover and stiffen a deteriorated roof without the necessity for extensive removal of the original roof covering, the deteriorated roof structure further stiffened by spaced stiffening ribs that also serve to fix in interlocked engagement the sheet metal roof covering pieces. Included in the assemblage are interlocking valey pans that are sequentially compressed between the ribs and then fastened with the valley pans then bridged by curved sheet metal caps that are also interlocked. The resulting structure has the pleasing appearance of an Oriental tile roof.

Abstract: A modular drainage system and/or assembly for flat-roofed or low-slope roofed structures available without field fabrication.

Abstract: A roof system for sloped metal roofs utilizing plywood decking, corrugated metal panels and one or more spacers disposed between the decking and metal panels for holding the metal panels vertically above the decking. The spacers have a planar top section, a planar bottom section and a center section to hold the top and bottom sections in spaced apart relation. The spacers also have one or more openings to form an airflow cavity between the decking and metal panels to permit the circulation of air therein. In the preferred embodiment, a thermal barrier layer is disposed between the spacers and the decking and the airflow cavity connects to a ridge vent located at the ridge of the roof and an eave vent at the eave of the roof. The roof system allows ambient air to be drawn into the eave vent to circulate through the airflow cavity and out the ridge vent in order to prevent thermal flexing of the metal roof and the build-up of moisture between the metal panels and decking.

Abstract: An apparatus secured to extend upwardly from a rooftop for redirecting free oncoming flow of a gas passing over an edge of the rooftop. The apparatus has an elongated member having at least a lower flow-surface, and a leading edge portion having a leading-rim extending therealong. A plurality of supports is spaced along the elongated member. An upper-end of each support is secured to, integrated-with, or otherwise extends from the lower flow-surface of the elongated member. There may be several such elongated members that may be joined. The lower-end of each support extends from the rooftop or sidewall structure to provide a spaced relationship between the lower flow-surface and the rooftop. The leading-rim of the leading edge portion extends into the oncoming flow to redirect of at least a portion thereof so that it flows under the leading edge portion and along the lower flow-surface and, preferably, on into a re-circulation region above the rooftop.

Abstract: A new mounting system for elevating and supporting objects such as solar panels and satellite dishes upon a roof. The mounting base for attachment to a roof rafter incorporates a threadable elongated member or stanchion and only requires a single lag bolt which is positioned directly beneath the stanchion for fastening to a roof rafter. A guide tunnel is also provided on the roof mount for proper drill angle into the rafter. The solar panel support utilizes C-shaped extruded aluminum horizontal members where, upon fastening the solar panel to the members, enhances the strength properties from a C-shape to a square structural member. The disclosed design for the solar panel support and associated equipment which are attached to at least two mounting bases, permits efficient packaging, resulting in minimal packaging time and cost.

Abstract: The roof shingle system of the present invention includes rows of shingle elements having parallel, slanting lower edges that are aligned to divert the flow of water away from areas where high flow volumes are not desired toward areas where high flow volumes will not cause harm. Because water flowing down a surface will tend to adhere to that surface, the water flowing down the surface of the shingle system of the present invention will tend to follow the slanting lower edges of the shingle elements in the direction of the slanted edges so as to provide a way to control the flow of water on the surface of a roof.

Abstract: Roofing brackets include a first leg that can be attached to vertical members of a roof structure and a second leg that extends at an angle from the first leg and can be attached to horizontal members of the roof structure and/or to a support surface. One or both of the first and second legs includes a plurality of preformed patterned holes having sizes that can receive fasteners. A roofing structure is fabricated using the roofing brackets.

Abstract: Roofing structure includes roofing brackets having a first leg attached to vertical members of a roof structure and a second leg that extends at an angle from the first leg and attached to horizontal members of the roof structure. Brackets serve to attache the vertical members to a support surface of the roof. The first and second legs include a plurality of preformed patterned holes and slots having varying sizes to receive fasteners. The pattern and size of the holes and slots allows for fastening of the brackets to steel bar joists while enabling the fasteners in the slots to be fastened near center lines of the respective bar joists. The slot sizes and positions enable fastening to steel bar joists for most distances between the flanges of their top angle chord members.
