If you have recently scheduled a metal roofing installation for your home, then you are investing in a strong and durable material to protect your house. A steel roof will last you around 60 years, and this makes it much better investment than an asphalt shingle roof. However, you may be concerned about some negative aspects of metal roof ownership that you have read online. Many of these negatives are actually myths. Keep reading to learn about the truth behind a few things that you may have heard.
Myth: The Roof Will Attract Lighting To Your Home
A steel roof will simply not attract lightning to your house. Lightning occurs as electrical ions of different charges build in the air between clouds, or between the clouds and the ground. As both positive and negative charges build, the air insulates them and it keeps them from interacting with one another. When the current from the ions becomes too strong, the air barrier breaks away and you see a quick discharge of electricity. This discharge is lightning and it is the release of electrostatic energy once the ions in the air interact with one another. The resulting lightning is negatively charged energy.
The charge of the lightning makes it unstable, and it searches out a positively charged environment to stabilize. The ground is positively charged, and this is why lightning will seek out a path to the earth. The path of least resistant is usually found so the energy can quickly move to the ground. This is why the lightning will strike the tallest object in the region since this will allow for the easiest and quickest movement to the earth.
Metal roofs and metal materials in general can conduct electricity, but they do not directly attract it. This means that a metal roof will help the electrical current move through it, but this will only occur if lightening happens to hit it. This is not more likely to happen than with a slate, asphalt, or rubber roof. Even if lightning were to hit the top of your home, you would be safe. The metal is resistant to fires. This is not true of some other roofing materials, and this means that your steel roof can actually protect you from house fire related incidents caused by lightening.
Myth: Metal Roofs Are Destroyed By Hail
It is true that hail will dent your metal roof. If the hail is strong enough to cause dents in your steel-bodied car, it will probably cause similar damage to the roof. This is not surprising since a hailstone that is about one centimeter around will fall at about 9 meters per second. Velocity is gained as the hail drops, and this can result in thousands of pounds of pressure against a small area of your roof. While this may be considered a negative, this same type of pressure can create a hole in an asphalt roof or break apart a slate tile. This will result in leaks and the need for an immediate repair. This is not the case for the steel roof since the dent will not reduce structural integrity. It is simply an aesthetic concern.
If hail storms are common around your house, then it may be wise to invest in a textured steel roof that will hide small dents and other imperfections. Honeycomb, corrugated, tile, and other types of textures are available. Speak with your roofing specialist so that options can be examined before you make your choice. Textured steel roofs come in the same long sheets that smooth metal varieties do, so the installation will typically be the same. You may need to pay a bit extra for the textured metal though, since it may require special ordering.
Steel roofing can be quite advantageous, but some people believe negative myths about the roofing material. Do not let this stop you from investing in the roof. Contact your local metal roof repair and installation expert to learn about the truths about the roofing material.Share
