Cut the piece large enough to cover the hole and 6 inches of the surrounding roofing each way, using sheet metal cutters. Apply base coat on the underside of the piece and install it on the roof. Cover the patch and surrounding area with glass-membrane fabric and apply a coat of urethane cement over the entire area. Patching Materials for Metal Corrugated Roofing Sheets Obtain some roofing mesh and cut out 2 identical square patches. Press one patch over the roofing cement. Let it conform to the contours on the metal panel. Spread some more roofing cement over the roofing mesh then attach the other square patch. Gain access to the roof.
