Abstract A roof snow guard in the form of a flat base member mounted flush to an inclined building roof and extending parallel thereto in the direction of incline and having a wing member extending angularly outwardly of the base member at the lower end thereof to prevent movement of snow or ice on the roof, which is formed integrally with the base member of molded clear plastic to render the snow guard practically invisible on the roof, reduce cost, and prevent discoloration of the roof during weathering of the snow guard since it is immune to corrosion.
