    Abstract: A roof removal machine may include an auger assembly at least a first helical auger flight coupled to a central axle, and a plurality of blades coupled to an outer edge of the auger flight. A motor is operably coupled to the auger assembly and configured to rotate the auger assembly about the axle in at least a first direction of rotation. The blade edge of each of the blades is oriented transverse to the first direction of rotation. In some examples, a second helical auger flight is also coupled to the central axle, and the two auger flights may be oppositely-handed with respect to each other, such that roof debris is moved toward a central extraction port.
