Understanding the new standards for safety, sustainability, and well-being through an overview of the NSF/ANSI 347 will provide the basis for specification and adherence. Codes have changed, relative to Low Slope design and Edge Standards to comply with those codes. Additionally, system design now allows the specifier and their clients to merge low slope and steep slope roof assemblies through one source. Compatibility of those systems is critical to performance, workmanship, and warranty. All of the key elements for total system design that will perform and meet the new code standards offer the design professional greater control of their intended design and its performance. Finally, knowing the importance of the materials used to manufacture steel, comparing Galvanized to Galvalume along with the Grade of the steel provides design professionals with a clear knowledge of strength of steel versus the perception that thickness is more important. The thickness of single ply membranes clarifies that not all single ply membranes are equal and thicker is not always better.
