Standing Seam Metal Roof Panels
A standing seam roof system, also classified as concealed fastener panels, utilizes a series of adjoining panels that are connected by raised seams (or vertical legs). Seam heights vary, but are typically 1 to 2 ½ inches tall and allow the panels to snap together without any exposed fasteners. In addition to providing a sleek, modern look, standing seam roofs allow panels to expand and contract with changing temperatures, helping them to last longer and cause less wear and tear on the roof deck. For residential applications, most standing seam panels snap together while others require mechanical seaming. Mechanical seamed panels provide greater strength and wind uplift capabilities.

These panels are better suited for application like eyebrows over windows or other accent installations. For most homeowners, newer standing seam models such as Meridian or Medallion-Lok are a better option in terms of weather resistance and performance.
