Do I need a lightning rod on my house?

There is no good reason why lightning rods (and the associated assembly consisting of a connection to earth and a ground rod) are not routinely added to houses. However, most high buildings and other structures do have some kind of lightning protection system incorporated into them.

Similarly, you may ask, is it a legal requirement to have lightning protection?

This could be the case, for example, when considering the protection of heritage properties. Although lightning protection is not a legal requirement for all buildings and structures, the requirements of the Electricity at Work Regulations 1989 (ref 7) will apply to most businesses.

Do lightning rods attract lightning?

Print. Lightning rods, first invented by Benjamin Franklin, do not attract lightning, although a lot of people think they do. If lightning strikes a house or a tree, it could cause a lot of damage. Lightning looks for the easiest path to travel and lightning rods are good conductors of electrical current.

How much does it cost to install a lightning rod?

One reason may be the cost: to outfit a 2,500-square-foot house with a standard system, which includes several lightning rods (often called air terminals), and a central surge suppressor at the main fuse box, costs about $2,500, according to Underwriters Laboratories, the safety certification organization.
