Lightning rods or air terminals are rods of pointed copper or aluminum that are placed on roofs to direct currents to the ground, instead of through the building's plumbing or electrical systems. Lightning rods do not attract lightning, but simply provide a preferred path of low resistance for currents to travel to the ground. Lightning rod systems prevent physical damage and keep the protected structure from burning down by conducting current and the associated heat away from the structure. However, electromagnetic waves produced by lightning can induce current in nearby electrical wiring and circuitry. As mentioned earlier, this secondary effect of lightning can cause extensive damage to electronics, including computers and modems, televisions, telephones and answering machines.
If your church is at moderate to high risk of lightning strikes, Zurich recommends installing a lightning protection system, including air terminals, conducting straps or wires, and grounding rod(s). The system should carry the UL Master Label and be installed per the NFPA code #780 or to the Lightning Protection Institute's certification requirements. Although lightning protection systems do not prevent lighting strikes, they have proven to be the most effective means of protection. Be sure to inspect and maintain your lightning protection system at least annually against corrosion or other deterioration.
If lightning damage occurs
If your church is damaged by lightning, first call emergency services and follow any advice provided. Before proceeding forward with costly repairs, your next call should be to GuideStone Agency Services or Zurich. The sooner Zurich is notified, the sooner cost-effective repairs can be completed. Zurich will help you identify services that are appropriate for your church. Do not assume that all repairs recommended by a service company are necessary or will be approved for payment. Again, coordination with Zurich is essential.
Do not allow the service company to remove any parts or equipment from your premises until they have been inspected by Zurich or our designee.
When damages occur, call 1-877-889-GSPC (1-877-889-4772) to report the incident and to seek assistance from Zurich.
