Metal Roofing Systems

Union offers both exposed fastener and concealed fastener metal roofing systems for residential, commercial, and post-frame  applications. As the name implies, exposed fastener metal roofing¬   systems use screw fasteners that are visible on the exterior of the roof surface after installation. These exposed fastener metal roofing  products are economical, have been in service for decades, and are  extremely popular in a wide variety of applications. In concealed¬   fastener metal roofing systems such as our standing seam panels, the¬   screws are completely concealed and protected by the roof surface. This  metal roofing product gives standing seam panels very clean,  aesthetically pleasing lines. The metal roofing materials also exhibit  the very best in weather resistance and durability since the fasteners  are not exposed to the outside elements. We offer the three primary¬   types of standing seam metal roofing systems; screw flange, snap lock,¬   and mechanically seamed. Each of these metal roofing product designs¬   uses a slightly different method to secure the panel to the metal roof.
