Lightning Protection Systems

A lightning protection system is designed to protect a structure from damage by intercepting such strikes and safely passing their extremely high voltage currents to "ground." This system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground against potential strikes.

Each year thousands of properties are damaged or destroyed by lightning. Lightning accounts for more than one billion dollars annually in structural damage to buildings in the United States. What is not reported is the loss of business, the downtime and liability that occurs when businesses or commercial tenants are forced to shut down to repair lightning damage. Insurers now require higher levels of safety for commercial buildings, schools, hospitals, institutions, historic landmarks, sports arenas and other public venues, including the installation of lightning protection systems.

Common Questions

Do lightning rods actually attract lightning?

No; they neither attract nor repel lightning. If lightning strikes, a protection system simply creates a pre-determined path of low resistance to the ground, facilitating a harmless discharge of the lightning strike.

Our building is grounded; doesn't that protect us?

No; a building may be grounded to insure electrical safety. However, grounding is not intended to prevent lightning damage.

Our antenna is grounded; doesn't that protect us?

No; an antenna is not designed to handle a lightning strike. It allows dangerous current to enter the building.

Don't our trees protect our building?

No; many times after trees are struck, the lightning can be sideflashed to the surrounding building or structure.

Can't we install our own lightning protection?

No; an improperly-installed system may be very dangerous. Lightning protection is a very specialized industry requiring trained technicians. A proper system takes into account your building's design, construction, electrical components, soil condition, location and more.

Won't it ruin the aesthetics of our building?

No; the system can be concealed within the walls during the construction stage. For existing structures, conductors can be semi-concealed.
