Lightning

Lightning can cause considerable structural damage to a church building. A lightning protection system protects the building and the electrical systems and equipment by directing the electrical energy within a strike to earth where it can be discharged safely.

Unprotected churches are about five times more likely to suffer strike damage than one with lightning protection. Talk to your inspecting architect or surveyor about installing a lightning protection system.

Appropriate separation should be maintained between lightning conductors and other conducting material, especially a church's wiring system and electrical equipment, as well as bonding. A useful artical giving seperation calculations can be found here.

As part of the rise of metal theft, many lightning conductors have been damaged or removed. See the section on Metal Theft for further information on the prevention of thefts.
