How do I patch a hole larger than the 5″ RoofKit Cover Strip?
Cut a patch out of an extra piece of EPDM membrane larger than the hole, and round the edges of the patch. With Seam Primer and a scrub pad, clean the mating surface of the patch and the installed membrane a minimum of 4″ larger than the hole. Apply RoofKit Multi-Purpose Adhesive to the patch and the area surrounding the hole with a small-nap paint roller. After drying to a tacky touch, place the patch over the hole, roll the edge of the patch with a seam roller, and seal the edges with RoofKit Rubber Caulk.
