Abstract: A flashing arrangement for mounting of a roof element in a roof having a thin sheet-formed roofing comprises flashing elements for connection with the main frame members and is made from a sheet material. The flashing elements intended for connection with the side members of the main frame are of a substantially L-shaped cross-section with an upright flange portion for bearing against the side member of the main frame and a flange portion protruding substantially parallel to the roof surface. The protruding flange portion is folded to form at least one slot in its longitudinal direction, said slot having an opening facing away from the main frame side member for receiving an edge portion of the thin sheet-formed roofing.

Abstract: Standing seam roofing system including first and second dikes integral with opposite longitudinal edges of a panel, and a roof connection ledge connected to the first dike and extending in the plane of the panel.

A lip on the second dike extends under a base on the first dike of the adjacent panel, the lip position being maintained by a pinching action or force produced by the slope of the downwardly extending leg.

Abstract: A frameless container of a predetermined length includes a floor having floor supports, a roof, a pair of opposing sidewalls and a pair of opposing end walls. One end wall includes an access door. The sidewalls are respectively connected to the floor supports and the roof. The upper portion of each of the opposing sidewalls has at least a first and second lap-jointed panels. Each panel has predetermined dimensions for the height, width and thickness. The lower portion of each sidewall includes a scuff plate. The bottom of the scuff plate is connected to the floor supports. The top of the scuff plate extends up from the floor by a predetermined distance defining a "scuff zone." The scuff zone has a projection-free surface exposed to the interior of the container. Fasteners attach the scuff plate to the lap-jointed upper wall portion and are arranged into a horizontal row located above the scuff zone. The fasteners have low profile heads which project only slightly from the inner surface of the scuff plate.

Abstract: A mid-roof anchoring system includes a series of anchoring channels secured to the roof structure along a line midway between the eave and the ridge of the roof. Metal roof panels installed over tile substructure are permitted to float laterally on the roof, except where they are attached to the anchoring channels. As a result, the roof panels expand or contract in both directions away from the midway line. This approach minimizes thermally induced movement the upper and lower edges of the roof, and minimizes reaction forces at the anchor.

Abstract: A method of restoring lapped metal roofs of, for example, steel or aluminum, and consisting of side-by-side panels having side and end edges which overlap to form edge joints, wherein the terminal edge of one panel is an exposed edge which extends over and overlies the edge of an adjacent panel to form an elongated joint, and wherein fasteners extend through the lapped panels to secure the panels together and in place. The method involves applying a flexible, formable rubber to cover the exposed terminal edges of the panels along their lengths. The rubber strips adhere to the panels and are stretchable with temperature-induced expansion and contraction of the panels. Similar strips are applied over all exposed fasteners, and then a substantially non-elastic asphaltic coating is applied over the strips and roof panels to bond to each. With temperature-induced relative movement of the roof panels, the coating cracks and separates and moves with the elastic strips as they stretch.

This panel provides a greater panel width per sheet stock width, ease of assembly, spacing and tracking surfaces for continuous edge seaming, and balanced strength with respect to loading.

Abstract: A ridge element for corrugated roofs is made as a monolithic tile member (2) having an upper arched shell portion (4), the underside of which is provided with protrusions (8) showing exterior edges (10) profiled so as to be engageable with the corrugations of the opposed roofing elements (12) when these form a specific ridgeangle with each other. The same or similar ridge elements will be advantageously usable for other ridge angles, too, because a relative tilting of the roofing elements will produce small gaps only between the surface thereof and the non-engaged portions of the tile edges (10), whereby a complete sealing will require relatively small amounts of sealing compound. In practice, therefore, one type of ridge tile will be usable for all relevant ridge angles, Preferably the tile edges are provided with compressible sealing strips which will normally obviate any additional use of sealing compound, whereby the tiles are very easy to mount.
