BIDIRECTIONAL ROOF SEAMING MACHINE ABSTRACT OF THE INVENTION A roof seaming machine has symmetrically arranged forming rolls and a reversible permanent magnet motor for operation of the machine in either a forward or reverse direction. Adjustable linkage connects the forming rolls with an articulated handle for moving the forming rolls relative to a drive wheel which propels the machine and which is adapted to be disposed on the opposite of a seam from the forming rolls. A reversible switch is connected to energize and deenergize the motor, and a directional switch safety guard is assoc- iated with the switch to limit its movement between an "off" position and either one of two "on" positions, depending upon the positioning of the guard.
