A ski device for use in combination with a snow removal device (such as a roof rake). The ski device includes ski portions that may be used to protect a surface (such as a roof surface) from damage by preventing a head of the snow removal device from directly contacting and scraping along the surface from which snow, ice, and/or debris is to be removed. The ski device also allows the amount of clearance between the head of the snow removal device and the surface to be adjusted. This allows a user to position the ski device to provide for a desired amount of clearance, which allows for adjustment of the amount of snow, ice, and/or debris that is to be removed, as well to allow for clearance of other structures (such as rain deflectors, etc.) on the surface.
