A standing seam roof is a type of metal roofing system characterized by vertical seams that rise above the plane of the roofing panels. These seams are interlocked and secured, creating a watertight seal that protects the building beneath. The design allows for thermal expansion and contraction, making it ideal for various weather conditions. Standing seam roofs are commonly made from materials such as aluminum, steel, and copper, and they are often used in commercial, industrial, and residential buildings.
