Do I need Protection against lightning? Yes, Proper protection against lightning damage can save you a lot of costs in replacing sensitive equipment. A quality surge or lightning protection device is designed to prevent damage to electrical equipment from over-voltage transient events by blocking or redirecting surge current to the ground instead of passing through the equipment. Surge protection is connected to a conductor on the line side of equipment – Surge protection is separate from lightning protection system.
Lightning rods intercept the voltage, providing a safe path for the powerful lightning current to flow into the ground and avoide damage as far as possible. They do not decrease the likelihood your home may be struck, but provide a direct path to ground, preventing damage to your home from fire, explosion, and electrical surges that can result from lightning strikes.
Proper protection will not keep your house from being struck by lightning, but a properly installed system will instead provide a safe path from the site of the lightning strike (which is often on the roof) to the ground. This minimizes the damage your home will sustain. In most situations, it is not necessary to install lightning rods on your metal roof. Lightning strikes to homes are rare, however the damage it causes are ofthen quite shocking and can be avoided by having proper protection installed on the property. If your roof is the highest point of a surrounding area, you may consider having a lightning safety system installed on your home.
