Lightning protection is not a do-it-yourself project. Only experienced and reputable LPI-certified lightning protection contractors should install lightning protection systems. Qualified specialists use UL-listed materials and ensure that methods of installation comply with nationally recognized Safety Standards of LPI, NFPA and UL. Design and installation is typically not within the scope of expertise held by homeowners, electricians, general contractors or roofers. Only trained experts, like LPI-certified contractors that specialize in lightning protection, should install these systems.
