The words “metal roofing” can frequently conjure images of warehouses or storage facilities. While those are certainly a few applications, they're not the only ones. Standing seam refers to a high-quality roofing system in which the fasteners are concealed from sight and, therefore, from the elements. Because the roofing is attached with clamps, there are no nail or staple holes. Advantages of standing seam roofing include its clean modern design and variety of colors and surface textures. These roofs are also low maintenance and energy efficient.
