Roof lightning rods.
Roof finials and ornaments lightning protection.
It is a very common misconception that a lightning rod attracts lightning.
Lightning rods are typically installed around the perimeter of flat roofs or along the peaks of sloped roofs at intervals of 6 1 m or 7 6 m depending on the height of the rod.
Let us understand it this way.
Does a metal roof need a lightning rod attached.
A one foot steel rod is included with each finial but the mounting bracket must be purchased separately.
A lightning rod is erected on the roof of a building and it is connected to a conducting channel to take the huge discharge of electricity into the ground.
Depending on the building s size and configuration additional air terminals are required around the roof perimeter at intervals not exceeding 20 feet within the field of the roof on rooftop equipment and as dictated by the standards.
The most obvious above roof components are air terminals formerly called lightning rods.
The only aim of a lightning strike is to neutralize itself with the ground.
