Lightning Rods for Houses
The most frequently asked question is whether or not a person needs lightning and surge protection installed on their property and there is really no good reason why lightning rods are not added to houses from the get go. Most of the higher building types and other structures do have some kind of lightning rods or other lightning protection system incorporated into them.
Lightning rods for houses are very affective. At the very worst case of lightning strike damage, the current might damage the lightning rod and can easily find another conductive path, such as building wiring or plumbing, and cause fires or other disasters. Grounding systems without low resistivity to the ground can still be effective in protecting a structure from lightning damage. Lightning rods for houses that are installed and designed proper will reduce the risk of such damage.
Contrary to a popular belief, a lightning rod for houses and structures does not serve to prevent a lightning strike at all. The presence of the lightning rod on the building can only serve to divert the dangerous charge from the lightning bolt to the ground safely through a low resistance pathway and in this way protect the building from the probable damage which would otherwise be caused by the lightning strike.
There is a very popular myth that claims that if you are in a house, you are 100% safe from lightning – THIS IS FALSE. The fact is however that a house is a safe place to be during a thunderstorm as long as you avoid contact with anything that conducts electricity. This means not using corded phones, electrical appliances, wires, TV cables, computers, plumbing, metal doors and windows.
