Abstract: A rear roof visor is provided as an apparatus that is designed to prevent sunlight from obscuring a driver's vision through a vehicle's rear window. The rear roof visor accomplishes this by preventing sunlight from being reflected off of a surface positioned underneath the visor. The rear roof visor is constructed utilizing a durable translucent material that allows the driver to see through the visor if needed. The visor is particularly formed and shaped in order to cooperatively function with the vehicle's aerodynamic characteristic reducing disruptive airflow. The rear roof visor attaches to the vehicle through the use of mounting brackets and a mounting lip. The mounting brackets and the mounting lip are specially formed in order to fit a vehicle's particular contours. Additionally the mounting brackets and the mounting lip utilize adhesive couplers in order to securely retain the visor to said vehicle.
