Lightning protection systems (lightning rods) should be inspected every three to five years by a firm that specializes in lightning protection, is UL listed, and their installers have qualified by exam as Master Installer by the Lightning Protection Institute.* The cost is typically in the $125 range. They should be called out immediately if you believe that you took a lightning strike, have added on, or planned to re-roof. If you have purchased a home with a lightning protection system and you do not know who installed it or when it was last inspected you may wish to contact an installer who meets the aforementioned criteria.* Generally, roofers are not experienced with lightning protection systems.* In this case the question is how does a homeowner know that the system was re-installed to NFPA-780, Standard for the Installation of Lightning Protection Systems, 2017 edition?
