This patent discloses a system to remove accumulated snow and ice from the trailer rooftop of the semi-trailer truck. The system includes tracks, sensors, a control switch, a blade, an axle, a left cogwheel, a right cogwheel, a left motor, and a right motor. The tracks are attached to the trailer rooftop and the blade is connected to the tracks through the left cogwheel and the right cogwheel. The left and right cogwheel may rotate about the axle that passes through the blade. The left motor and the right motor are configured to be in communication with the sensors and control switch. If the sensors detect snow on the trailer rooftop or if the control switch is pressed, the motors cause the blade to move along the trailer rooftop to clear off any accumulated snow.
