Abstract: A standing seam paneling system comprising a plurality of elongated flat panels having upturned side edges arrayed in side-by-side relation on opposite sides of a series of longitudinally aligned spaced apart clips secured to a supporting surface. Each clip includes a generally rectangular upright body section having an integral flange-like foot section extending outwardly from its bottom edge for fastening the clip to the underlying support surface. The upper part of the clip includes a pair of angularly contoured members extending upward from a longitudinal row of perforations and adapted to be folded over in opposite directions over the upturned side edges of adjacent panels to secure them to the surface. A sealing cleat cap is installed over upturned panel edges and the retaining clips.
