Standing seam metal roof installation involves securing long metal panels vertically along the roof's surface, with raised seams connecting adjacent panels. The process begins with preparing the roof deck and installing underlayment for weather protection. Next, installers attach the metal panels using specialized clips or screws along the seams, allowing for expansion and contraction. Seams are then crimped or mechanically seamed to ensure watertightness. Flashing and trim pieces are added around edges and penetrations for added protection.https://www.crownroofingsolutions.com/maintenance
