Can lightning go through a metal roof?
Extensive research on lightning protection reveals that metal roofing is no more likely to attract a lightning strike than any other type of conventional roofing material. This is because when lightning strikes a home or building, it doesn’t matter if the materials it hits can conduct electricity or not.
How do metal roofs not get struck by lightning?
A metal building system, with a conductive metal roof and a conductive metal structural frame, gives lightning a low-resistance path to the earth. A metal building may survive a lightning strike with less damage than a similarly sized and located building made of higher-resistance materials.
Do metal buildings attract lightning?
Contrary to urban myth, steel buildings resist lightning, not attract it. The height of a structure, not the framing material, determines the probability of a direct lightning strike. The taller the building, the greater the risk that lightning might hit it.
Do houses with metal roofs need lightning rods?

Does a metal roof have to be grounded?
Why do modern homes not have lightning rods?
Perhaps it’s because the chance of a lightning strike is, for most houses, quite low. However, most high buildings and other structures do have some kind of lightning protection system incorporated into them.
Should I ground my tin roof?
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.
What happens when lightning strikes a metal roof?
