- Type: Metal
- Official Name: Standing Seam
- Description: Standing seam metal roofing is defined as a concealed fastener metal panel system that features vertical legs and a broad, flat area between the two legs. It's also described as having raised seams, or vertical legs, that rise above the level of the panel's flat area. Standing seam systems can be used for either metal roofing, which is the most common, or metal walls. The main idea to remember for standing seam systems is that the fastener is hidden, whether the panel is attached to the roof deck using a clip or is directly fastened to the decking material under the vertical leg using a fastener flange.
