Many homeowners hesitate to install metal roofing because of the pervasive myth that it attracts lightning. In this blog, roof repair contractor Universal Roofing & Exteriors dispels this myth and shares why metal roofing is one of the best roofing systems for all climates and weather conditions.
Lightning Behavior
The myth about metal roofs being a “lightning magnet” is probably due to the fact that metal is a highly conductive substance. While this is true, it has nothing to do with how lightning behaves. Lightning will not strike a home just because it is made of metal; it will simply strike the tallest structure in its path. In the unlikely event that lightning does hit a metal roof, the inhabitants of the home will actually be better protected because metal is so fire resistant.
Lightning behaves like a typical electrical discharge: it seeks the path with the least resistance. Therefore, lightning will almost always hit the tallest grounded structure in the area, which could be a tree, a bell tower or a satellite dish. This is why lightning rods are supposed to be the tallest component of the home they’re installed on. In the event that lightning does hit a metal roof, the surface conductivity allows electricity to safely dissipate to the ground.
Other Advantages of Metal Roofs
Metal roofing systems offer more than just lightning protection, such as a long lifespan that’s almost twice as long as traditional asphalt shingle roofs. In addition, metal provides exceptional impact resistance, ideal for areas prone to hailstorms. Its smooth surface sheds rain and snow efficiently. Metal roofing systems are also lighter than asphalt shingles, making them easy to install on almost any type of home or building.
Metal roofs are nothing if not aesthetically versatile. Standard standing seam roofs can be coated with virtually any color, which makes it easy to plan an exterior color palette. Reflective coatings can make a metal roof more energy-efficient. Certain options such as copper and aluminum roofs can be installed bare. Lastly, metal roofs are highly recyclable, and are therefore one of the most eco-friendly roofing systems available.
