A mounting device for covering a roof penetration in a roof includes a base having a central hub, an outer perimeter structure, a top which is open, a bottom which is open, and ribs extending from the hub outward to the perimeter structure. A continuous internal reservoir extends between the hub and the perimeter structure, for holding a sealant against and in cooperation with the roof. The reservoir unsevered by the ribs. A cap is moveable onto the base for forming, in cooperation with the perimeter structure, an environmental seal over the roof penetration.

A fastener installation tool is provided for installing threaded fasteners through a washer plate having a center hole used in connection with roofing membrane installation. The installation tool is configured to receive different types of washer plates, and is easily dis-assembleable in the field without the need for tools in order to easily and simply clear jams.

In a continuous screw tightening machine with washer stacking supply mechanism, in conjunction with retreating of a tightening machine, a washer is placed on a seat surface portion of a washer feeding body of a washer sequential supply mechanism and reliably supplied to a tightening possible position one by one and the one screw is supplied by a screw sequential supply mechanism between the washer and a bit so as to be in concentric arrangement, in conjunction with advancing of the tightening machine, the washer sequential supply mechanism is set to a feeding preparation attitude of the subsequent washer, and the screw sequential supply mechanism is constituted to be set to a feeding preparation attitude of the subsequent screw, and the screw is tightened and fixed together with the washer at the tightening target spot by rotation/driving of the bit advanced to the tightening possible position by a driving machine.

An integral nail/disk structure that eliminates the need of having any exposed nails associated with a shingled roof having a color matching body member integrally formed with a roofing nail. Another embodiment including a fastener such as a nail or screw having an enlarged head and an associated gasket member for fastening sheet metal to a roof structure. The gasket member has a sealant on both of its top and bottom surfaces so as to adhere both to the underside of the enlarged head portion of the nail or screw, and to the sheet metal to create a waterproof seal. Still another embodiment includes an enlarged cap member associated with a gasket member attached to its underside portion wherein the cap/gasket member can be attached over a fastener hole in a roof, or over a faulty roofing nail or screw in lieu of caulking techniques usually used to cure leaks where the faulty fastener attaches sheet metal to a roofing structure.

A roof-mounting device for covering a roof penetration in a roof includes a base having an open top, an open bottom, and an outer perimeter structure. An internal reservoir of the device is in communication with the open top and the open bottom, and a mount plate is disposed in the internal reservoir extending between opposed ends of the outer perimeter structure. A bore is formed in the mount plate below the top of the base, the bore for receiving a fastener for fastening the mounting device at the roof penetration. When the bore receives the fastener therein, the internal reservoir is unsevered, remaining in communication with the open top and open bottom of the base.

A flat roof washer and heat welding installation system (1) for securing rigid roofing panels and overlaying membranes to a flat roof truss system comprising one or more wheeled carts having a plurality of screw guns (12) and/or heat welding heads (16) arranged in grid patterns to allow for quick and even installation of screwed washers and heat welds on a flat roof.

A mounting device for covering a roof penetration in a roof includes a base including a hub, an outer perimeter structure, a top, a bottom, and ribs extending from the hub outward to the outer perimeter structure. An internal reservoir extends between the hub and the outer perimeter structure. A mount plate is disposed in the internal reservoir between the hub and the outer perimeter structure. A bore is formed in the mount plate.

A method of covering a roof penetration in a roof includes providing a roof mounting device comprising a base, an outer perimeter structure, an open top, an open bottom, and an internal reservoir bound by the outer perimeter structure, and a fastener. The method includes securing the roof mounting device to the roof by applying the fastener to the base and to the roof penetration. The method includes applying a sealant to the internal reservoir until the sealant seals the fastener at the roof penetration.

A mounting device for covering a roof penetration in a roof includes a base having a hub, an outer perimeter structure, a top which is open, a bottom which is open, and a dome extending from the hub to the outer perimeter structure. An internal reservoir extends between the hub and the outer perimeter structure for holding a sealant against and in cooperation with the roof. A rib is formed to an underside of the dome and extends radially outward from the hub toward the outer perimeter structure.

A commercial roofing screw machine has: a plurality of screw guns that each properly place and install screw and washer pairs, both securely and in the right location, from separate magazines; automated operation with automatic or manual fastening pattern selection; sensors to recognize insulation sheets or marking lines, the high and low rib on the decking through the insulation, and torque; an indicia generator that marks fastener locations that did not hold correctly; and wireless communications for remote status checks, new programming uploads, troubleshooting, issue and error reporting, communicating with like or complementary machines to complete tasks, communicating with a records and reporting system to document fasteners installed correctly and which ones failed and were fixed by humans, and other beneficial purpose, and enabling plans upload with feature locations identified to select a fastening pattern based on location on a building and wind uplift ratings.
