A windshield roller assembly that may be retrofitted to existing wiper arms and that provides a rolling surface so that it is able to conform to surface irregularities and expel dirt and debris from low spots. The rolling surface avoids scraping the windshield glass and is not subject to the shear forces incurred by scraper type blades. The windshield roller is generally a simple cylindrical shape about a flexible shaft such as carbon fiber rod. The geometry of the roller is most typically an elongated frusto-conical shape so as to trace an arced path.
