210 Roof Cover: Copper

This type of roof is made from copper and copper alloys and may be applied as formed seam sheets or rolls. It is most frequently applied in a flat, standing or batten seam method by hand or machine formed. When applied in rolls, the flat seam method has flat locked and soldered joints normally held down with copper cleats. The standing seam method can be applied over sloped roof surfaces with the seams being finished and standing about 1" high. Batten seams are formed with the use of a narrow strip of wood that forms the seam. Normally the seams are unsoldered with the joints being staggered. The spacing of the seams is characteristically a function of the architectural design of the roof.
