New Edition
The 2024 edition of the International Building Code® (IBC), will include new language that clarifies how Lightening Protection Systems (LPS) are secured to commercial roof assemblies, roof coverings, metal edge systems, and gutters. The language, which goes beyond the existing installation standards outlined in NFPA 780 and UL 96A, was developed by the Single Ply Roofing Industry (SPRI), which worked closely with the National Fire Protection Association members, the National Fireproofing Contractors Association, the Lightening Protection Institute, the National Electrical Manufacturers Association, Underwriters Laboratories, the National Roofing Contractors Association, and other stakeholders to build consensus to get the new language approved and adopted for the code in 2024.
The new language, which will be added as new sub-sections in Section 1511 Rooftop Structures, stipulates that LPS installations must be completed in accordance with the roofing system or edge metal manufacturer’s instructions, or specifications from a qualified design professional. Where LPS components are secured to, or penetrate the roof, they must be properly flashed. The 2024 edition will be published towards the end of 2023. Once published, the new language for securing LPS on commercial buildings may be adopted by states and jurisdictions across the United States, and around the world.
