Abstract: A novel tool and method for making the tool for bending roofing material having uniformly spaced support ribs. The bending tool has a channel for bending roofing material having uniformly spaced support ribs. The dimensions of the channel height and length are based on properties of the ribs of the roofing material on which the tool is to be used, specifically the height of the ribs and the distance between two consecutive ribs. The tool is made by taking these measurements of the ribs and fabricating a channel based on these measurements. The channel is formed by two flanges attached to a solid upper base. The entire base is attached to a handle.
