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.
