The present invention relates generally to the field of vehicle snow clearing systems and more specifically, to an apparatus for clearing snow and ice from the roof or top surface of a commercial vehicle such as, a tractor trailer. The apparatus includes at least one upright member with a longitudinal axis and a lifting carriage assembly coupled to the at least one upright member for movement along the longitudinal axis thereof. A carriage driving assembly is operatively connected to the lifting carriage assembly and the lifting frame for selectively moving the lifting carriage assembly along the longitudinal axis of the at least one upright member. Also provided is a snow clearing assembly carried by the lifting carriage assembly and positionable on the roof or top surface of the vehicle. The snow clearing assembly includes a housing, blower means disposed at least partially within the housing for casting snow from the roof of the vehicle and a pair of first and second, spaced apart, auger members rotatably mounted within the housing for directing snow on the roof of the vehicle toward the blower means. The first auger member is disposed frontward of the second auger member. The lowest extremity of the first auger member is spaced away from the roof or top surface of the vehicle, when the snow clearing assembly is positioned onto the roof or top surface of the vehicle. At least one portion of the second auger member is constructed of a resilient material so as to allow the at least one portion of the second auger member to flex when borne against the roof during actuation of the snow clearing assembly.
