The Importance of Metal Roof Edge System Testing

Years ago, the American National Standards Institute (ANSI) and Single Ply Roofing Industry (SPRI) developed standards to test wind loads and the wind uplift pressure to the edge of a metal roofing system installed on any commercial building. SPRI released their own statement regarding this topic: “It is the opinion of SPRI that a critical element in meeting a design standard is a fabricator’s manufacturing capabilities. Therefore, ANSI/SPRI ES-1 testing should be performed on systems as manufactured by a given fabricator.” To help fabricators meet this requirement, we act as a non-biased, third-party tester to ensure the product’s quality.
