Even lightning can’t hurt a metal roof

Metal roofing in Charlotte, NCLong-lasting metal

Metal roofing eventually makes back the cost of its installation, because if properly maintained it will last 40 to 60 years — longer in some cases. This saves you the money you’d have to spend on replacing it.

Metal roofing has other advantages as well. It’s surprisingly lightweight for the strength it offers — it tends to be from 50 to 150 pounds per 100 square feet. With standing seam roofs, the most popular type of metal roofing, the seams are few and elevated, reducing potential leaks. In some states, a metal roof can cut homeowners’ insurance premiums by up to 35 percent. It doesn’t heat up as much, which will lower your AC bills. Made properly, it won’t even make noise in the rain.

As far as price goes, the least expensive metals are steel and aluminum. Galvanized steel can withstand the worst weather better, but aluminum is lighter and more rust-resistant. Copper is the most durable, but also (along with zinc) the most expensive. Ask your roofing contractor for a price list.

But there’s still one question that a lot of people worry about: what if it gets hit by lightning?

What happens when lightning strikes

There’s no use trying to stop lightning. By the time it hits your house, it has already passed through thousands of feet of resistant air, and it will force a path through anything — wood, brick, stone or flesh — on its way into the earth. A metal roof is no more likely to be hit than any other kind of roof.

The more a given material resists the lightning, the more of the lightning’s energy is converted into heat, the hotter the material gets and the greater the risk of fire. A metal roof combined with a lightning rod offers the lightning a smooth and easy path into the earth that bypasses your home’s electrical system, plumbing and sensitive electronics. Even if it isn’t connected to a lightning rod, a metal roof will spread the lightning strike over the entire structure, minimizing the amount of damage that will be done to any one part of it.
