McElroy Metal has introduced a method for installing standing-seam metal roofing directly over asphalt shingles without a tear-off. The system is designed around the patent-pending 138T Shingle Recover Clip and 138T symmetrical standing-seam panel. The main challenges when installing a metal roof directly over shingles with no underlayment are clip alignment and abrasion on the underside of panels. The 138T Shingle Recover Clip is long enough to sit on two shingles, aligning the clip into the plane of the roof. The clip has eight holes so the installer can align the fasteners through the ends of the shingle tabs. The clip’s 3/4-inch height holds the panel up so it does not touch the surface below but allows a contractor to walk on the roof without damaging the clips or panels.
