Standing Seam Roof Over Shingles

The system is designed around the patent pending 138t shingle recover clip and 138t symmetrical standing seam panel.

Standing seam roof over shingles. Architectural and premium shingles. There are two main reasons. Mcelroy metal has introduced a method for installing standing seam metal roofing directly over asphalt shingles without a tear off. The problem is that metal has such a large coefficienct of expansion and contraction that the fasteners are frequently worn out or broken.

In a standing seam roof long single panels run vertically all the way from the eave to the ridge. First of all if you install a standing seam metal roof over asphalt shingles there will be a so called telegraphing effect where shingles can punch horizontal lines in standing seam panels. Standing seam roofs are a little better than other types because the fasteners are hidden. Unlike steel and aluminum shingles standing seam panels should not be installed over the existing asphalt shingles.

Both field locked and snap locked panels the overall installation cost is 950 to 1 550 per square. In contrast steel shingles are small panels installed in horizontal rows much like other shingles. The main challenges when installing a metal roof directly over shingles with no underlayment are clip alignment and abrasion on the underside of panels. Standing seam metal roofing is defined as a concealed fastener metal panel system that features vertical legs and a broad flat area between the two legs.

The cost to install architectural shingles labor and material included comes in around 350 to 550 per square. Better steel shingle systems like the one shown install over a framework of 2x2s.
