ABSTRACT:
A hand tool is provided for swedging female seams of standing seam roof panels. The tool includes a handle and a seam-engaging structure. The handle and seam-engaging structure can either be integral or in two pieces. The seam-engaging portion has first, second, and third substantially planar surfaces with the first and second surfaces making an acute angle with respect to each other, and the second and third surfaces making an acute with respect to each other. When placed in operative association with a female seam having an end edge and first and second bends, the seam can be "opened-up" by effecting bending at the second bend, while not disturbing the first bend or end edge. To open up an entirely closed seam, the hand tool is placed at an endlap location and is impacted with a hammer to move from the endlap position to a more mid-seam location, and swedging is then effected.
