Through the cooperation of several related roofing contractor and design associations, the industry provides standards for single-ply roofing construction. The American National Standard Institute (ANSI) and the Single-Ply Roofing Industry (SPRI) have been instrumental in establishing standards for roofing material design and installation. . . .

A roof edge system must act as a water seal at the edge by protecting the membrane from pulling free under high winds or repeated seasonal wind cycles. If the edge leaks or blows off, damage to the roof membrane, insulation and/or the structural decking can occur. . . .

It’s important that roofing professionals comply with building codes.  A construction contractor whose work is not consistent with the building code in the jurisdiction where the work was performed may face civil liability for negligence, as well as contractual liability. . . .

The destructive power of Mother Nature’s high winds and its devastating effects on our buildings has dramatically changed how “low slope” roof edge systems are currently designed, manufactured and installed . . . .

The formulation for calculating a building’s design pressure is found in “ANSI/SPRI ES-1 and the Wind Design Standard for Edge Systems Used with Low Slope Roofing Systems.”  This calculation involves 5 key elements . . . .

Sample certification that the Product(s) have been tested in accordance with the protocols of the ANSI/SPRI ES-1 Roof Edge Standard, and when installed as required will withstand the Design Pressures as calculated using ES-1 for the below listed project, and as prescribed by Section 1504.5 of the International Building Code. . . .

National ES Testing Service Inc. can provide your company with tested roof edge products that not only meet the new local codes but also comply with the requirements of the 2003 International Building Code (IBC) . . . .
