Standing seam roof systems are often recognized as the best metal roofing system available. And without a doubt, they offer unparalleled protection when properly specified, manufactured, and installed. Unfortunately, as long as individuals are involved in the process, the potential for mistakes exists. In her latest column for DesignandBuildwithMetal, Kathi Miller of McElroy Metal roofers installation tips for a weathertight standing seam roof system.

Metal roofing is well-known for its outstanding performance against mother nature. From hailstorms to hurricanes, metal roofing performs better than other material options like membrane roofing and shingles. With that said, like with any other product, problems can occur. And while installation errors lead to most issues, panel side laps, incorrect panel profile selection, and fastener locations can be problematic for exposed fastener panel installations, particularly on lower roof slopes.

Manufacturer certification programs can be a source of confusion. Most often, the confusion stems from using words like “certified,” “approved,” “authorized,” and “qualified” interchangeably. While they may mean the same thing to architects and building owners, those terms often mean completely different things to manufacturers. Kathi Miller explains in her latest blog.
