Install the rod in a location near the electrical panel. Ground rods need to be installed in the ground outside in a spot where they can be hammered 8 feet (2.4 m) into the ground.
eight feet As a rule, ground rods must be a minimum of eight feet long and should not be cut down. In very dry ground, which provides more resistance than moist soil (meaning it does not accept electricity as readily), ground rods are sometimes stacked and joined with a special clamp so they can extend deeper into the earth. Jan 23, 2021
The short answer is no, a metal roof does not need to be grounded. In most cases, you will not incur additional risk if you don't ground it. Metal does conduct electricity. But when dealing with a full roof, a lightning strike would ground out through the structure, causing no more harm than non-metal roofs would. Jul 7, 2020
