Abstract
A shaped metallic roofing plate having a plurality of tile-shaped metallic rectangular elements adapted to be superposed at their upper and lower edges and side edges. Each rectangular element has a substantially S-sectioned bend formed along the upper edge thereof and a downward bend formed along the lower edge. The upper bend has a plurality of nailing surfaces extending in parallel with the roof surface and occupying a common plane. In assembling, the elements are nailed at their nailing surfaces to the roof surface such that the lower bend of the overlying element is placed and superposed to the upper bend of the underlying element. At one side edge portion of the element, there is formed is at least one groove extending in the direction of slope of the roof. When the other side edge portion of the adjacent element is placed on the side edge portion of the fixed element, a space is formed between the lower surface of the other side edge of the adjacent element and the top surface of the one side edge of the fixed element, thereby to prevent the possible capillary action.
