If you purchased a home with a metal roof, you may be worried about lightening strikes. That is normal, as there are a lot of rumors and myths going around. The simplest way to unveil the truth is to talk to an experienced roofing contractor in Hillsborough, NC. Installers know a lot about the materials they use every day. Here are some of the comments you can expect when you ask them about the possibility of lightening striking your roof.
What Is Lightning?
Lightning is a discharge of electricity in the sky. This natural phenomenon is triggered in a cloud by a buildup of differing charges. A lightening flash is a sudden release of energy. It becomes a bright flare, usually followed by a loud thunderclap. Lightning can strike anywhere, and appears in a variety of guises. Which one you will see depends on your local atmospheric conditions. Avoid a confrontation, as a single lightening strike can carry millions of volts of electricity. A hit can be deadly.
Probability of Lightning Striking Your House
It is true that metal conducts electricity. However, metal roofs do not attract lightening. They do not increase your chances of getting hit either. Why? The following factors increase the probability of a strike:
- Location: A house high up in the mountains or built on a hill has a higher chance of getting hit by lightening than one located on a flat field.
- Dimensions: A high structure with a large cover is at a bigger risk than a low building with a small roof.
- Neighboring buildings: Short structures near tall buildings are extremely safe.
- Vicinity: Some regions are more affected by thunder and lightning storms than others.
Metal Construction Materials Are Safe
Metal is actually much safer than other roofing materials for the simple reason that it is noncombustible and does not explode. If a metal roof is struck by lightning, it is less likely to start a devastating fire. The electricity could spread throughout a large surface. That is not the case with asphalt shingles or wood.
A roofing contractor in Hillsborough, NC, explains to his customers that the safest place to be during a bad thunder and lightning storm is inside an enclosed building in an interior room. If they are outside, people should seek shelter in a vehicle and keep the windows closed. They should not touch any conductive paths to the outside.
