Abstract: A sliding bracket assembly permits adjacent metal roof panels to move relative to one another to accommodate differential thermal expansion. The assembly includes a center element which is bolted across a purlin, and a pair of wing elements, one on either side of the center element. Roof panels are attached to the wing elements on either side. The wing elements can side lengthwise on the center element; thus the wing elements and their attached roof panels can move lengthwise relative to one another as the roof panels differentially expand and contract.

Abstract: A light-transmitting roof panel assembly, having the same shape as adjoining metal roof panels in a standing seam metal roof, includes an outer transparent panel made of a polymeric material and an inner reinforcing panel made of perforated metal. The inner and outer panels nest together and lie flush with the roof. Crimpable side corrugation pieces are attached to the reinforcing panel so that the assembly can be connected to neighboring roof panels by seaming.

Abstract: An apparatus for supporting a roof seaming machine on a roof has a frame formed by a pair of spaced support members. Each support member includes an arm having a slotted transverse channel member affixed to one end thereof, and a vertical column is connected to the opposite end of the arm. A platform for supporting the seaming machine is connected to the frame by a pair of hinge knuckles which allow the platform to be folded upward when the machine is not resting on it. The frame is secured to the roof by applying clamps to roof seams where the seams protrude through slots in the channel members, thus enabling the platform to support the machine beyond the edge of the roof.

Abstract: Notches are cut in a “Z”-section closure to be installed across seams on a standing seam metal roof by means of a tool which punches holes in the central web of the closure. The lower flange of the closure is subsequently cut manually to finish the notch. The tool's die surfaces correspond in shape to that of the closure, and the punch and die are aligned so that the elongate hole they make in the central web extends to the bottom of the web.

Abstract: A rectangular curb unit is installed on a sloping standing seam metal roof at an angle to the dip direction, so that water does not accumulate on the upslope side of the curb unit. The curb unit has four side walls, and inserts shaped to conform to the seam geometry are welded to the walls at the seam locations, typically at opposite corners.

Abstract: An apparatus for punching a plurality of predetermined spaced mounting holes in a building roof panel support member includes an elongated housing having an oil sump therewithin, a hydraulic pump together with an electric motor for actuation thereof mounted on the housing, guide structure which can be opened and closed for temporarily mounting the housing upon a roof panel support member, an adjustable gauge pin mounted on the housing near one end thereof, the gauge pin being supported on a mount which is adjustable along both the length and the width of the housing, and a hydraulic punch adjustably mounted near the other end of the housing from the gauge pin for punching holes in the support member.The method of punching holes in a roof panel support member as disclosed herein is also part of this invention.

Abstract: A fully adjustable, simplified system for installing a sloping roof on top of an existing flat roof is disclosed. Top and bottom roof spanning members are interconnected by individually vertically adjustable stanchions and the stanchions in the system are cross-braced in two orthogonal planes. The top and bottom spanning members of the system can be parallel or perpendicular to each other and the bottom spanning members can be eliminated and replaced by individual bearing plates where the existing roof structure allows direct loading at localized points. The system utilizes precut and prepunched components and utilizes offset hole punching to achieve a fine degree of adjustability which renders the system highly versatile.

Abstract: A hand seaming tool for use during original installation or re-roofing of roof panels of a building. A pair of main body elements, a pair of interconnected intermediate body elements, handle structure, limit structure, and an anvil head and forming bar all cooperate to permit an operator and user of the device to perform double seaming of the edge flanges of adjacent roof panels. Preferably, such operation occurs during initial starting of the double seaming and/or the final completion of such double seaming operation. A motorized roof seamer is normally used for the intermediate portion between the beginning and ending double seamed areas.

Abstract: A machine for cutting standing seams which connect roof panels together includes a cutter wheel located adjacent a platen wheel. The cutter wheel is movable and is moved toward the platen wheel by a jack-screw mechanism mounted on the frame of the machine.
