ABSTRACT:
Snow accumulating on sheet metal roofs may fall in large masses, causing damage to property and persons in its path. A method of impeding snow from sliding off metal roofs is provided. The method involves installing a series of attachment mechanisms which are generally U-shaped, so that each attachment mechanism straddles a roof seam. Each attachment mechanism is secured by screwing a blunt edged screw into a hole in a prong of that attachment mechanism to tighten that mechanism against the roof seam, without penetrating the seam. Each attachment mechanism is provided with a bar receiving channel to hold a bar perpendicular to the seams, to prevent large masses of snow from sliding off the roof.
