New construction. Standing seam roof installation.
A standing seam panel is flat with vertical legs on each side. Clips are used in this type of roofing system to eliminate penetrations in the panels. The clip runs over the vertical leg of the panel, down the side of the panel and then flat onto the decking. Once a fastener clip is installed, it is screwed down to the decking. This is what keeps the panel from uplift. The beauty of this roofing system is that the fastener and screws are completely concealed after the next panel is placed down.
