Conclusion
It is important to understand protecting the integrity of the building envelope is critical. Commercial roofing contractors are not experts in lightning protection installation, and lightning installers are not roofing experts. It is therefore the specifier’s or system manufacturer’s responsibility to clearly document how the roofing and LPS effectively interface, for the benefit of the building structure, equipment, occupants, and owner.
The 2024 IBC will be available for adoption by individual jurisdictions beginning in 2024. However, even if it has not yet been adopted for a specific jurisdiction, the impact of LPS on the performance of roof systems needs to be considered. Moving forward, manufacturers of edge metal systems and roofing materials will need to work with the lightning protection industry to provide clear installation instructions for this equipment, in conjunction with the roofing system.
It is also important to remember the IBC is written to benefit society, building owners, and occupants. There will always be conflicts among the various component providers, which need to be addressed and resolved by all parties. Building consensus is time consuming, difficult and requires compromise by all entities, for the overall benefit of the building owner and occupants.
