Standing seam solar flashing is a sophisticated waterproofing technique used on metal roofs with standing seams. It allows for the mounting of the solar panels without compromising the roofing system. It fits within the vertical seams of the roof and utilizes brackets or clamps that fit over the ridge of the seam in a non-invasive manner. Fabricated from galvanized steel or aluminum, these flashings have watertight seals and adjustable clamps for varying seam and panel geometry. They also allow for the rotational movement of the metal roof to mitigate potential leak paths due to expansion and contraction. Adhering to the installation requirements of the roof manufacturers and using neoprene gaskets or butyl tape for waterproofing these gaskets is critical for PV projects developed on commercial and industrial standing seam roofs.
