摘要：
A roof seaming apparatus for seaming a metal roof provides a frame having opposed upper and lower roller groups that can selectively engage and seam the roof panels depending upon orientation of the frame. When seaming a roof, the machine lower rollers engage the roof seam at the eave of the roof. The machine is powered so that the upper rollers from the seam as the machine travels to the roof crest. At the crest, the machine is inverted so that the upper rollers engage and form the seam from the crest to the opposite eave.
