A roofing panel system including a plurality of elongated panels disposed in side-by-side parallel array on a supporting roof structure, each panel having an upwardly projecting longitudinal flange along each side with the flanges of adjacent panels together constituting a standing seam at the junction of the panels. A plurality of clips, fastened to the roof structure along each standing seam and interposed between the adjacent panel flanges constituting that seam, engage the tops of the adjacent panel flanges to anchor the panels to the roof structure and also support the adjacent panels from below. Each standing seam is covered by an elongated cap member snap-fitted over the tops of the adjacent panel flanges and bearing sealant material which engages the tops of the latter flanges to seal the seam. The top portion of each panel flange is bent toward the other flange of the panel to form a leg, over which the cap member extends, having a flat upwardly facing surface for contact with the sealant material. The clips can be formed to support the panels in outwardly spaced relation to the roof structure to provide a gap for receiving thermally insulating material.
