    Abstract: A snow removal device for elevated positions, such as roofs, while remaining on the ground. The device includes a shovel type head 10 which folds back, to assist the slide motion up the surface of a pitched roof. The shovel type head 10 is spring 14 loaded to open upon the pull action. When in use, the operator places the shovel type head 10 end of the device on top of the snow covered surface. In this position, the shovel type head 10 is hinged back so as to have the convex side of the shovel type head 10 to the surface of the snow. This allows the device, with a pushing motion, while extending the pole handle 15, to slide on or near the surface. When the desired distance is reached, the pulling back motion of the handle 15 opens the shovel type head 10 with assistance of the spring 14 and resistance to the snow. This forms a scoop, or plow action, dislodging and removing snow downward from the roof.
