When it comes to roofing projects, you’ll be pleased to learn from your contractor that you have a wide range of options when it comes to materials. In fact, you can choose between materials such as asphalt shingles, wood and even metal for your roof. When it comes to metal, however, some homeowners are somewhat reluctant to install them in their homes out of fear that it might attract lightning. In fact, some are even wondering if they need to ground their metal roof before it’s installed in their property.
In this post, Turner Home Improvement discusses if you need to ground your metal roof.
Do You Need to Ground Your Metal Roof?
If you ask your roofing contractor whether or not your need to ground your metal roof, you might be surprised if they answer that grounding your metal roof isn’t necessary unless it’s mandated by the building codes of your area. This is because while metal may conduct electricity, a lightning strike on your roof would ground out throughout the rest of your home without causing damage to your interior. This means that you’re more than free to install a metal roof in your home without having to ground it as there’s no risk associated with having an ungrounded metal roof.
However, if you have any pipes extending from your home to the roof, keep in mind that you may only leave your metal roof ungrounded if you’re using PVC piping. This is because if you’re using a metal pipe and lightning happens to hit it during a storm, it won’t be grounded throughout the rest of your property and may cause damage to your home. If you have any metal objects within a few feet of the roof itself, on the other hand, consider grounding the roof as a safety precaution instead.
Factors That Influence the Likelihood of Lightning Striking Your Home
Whether you own a metal roof or not, there are still a few factors that can influence the likelihood of lightning striking your home and none of them include grounding a metal roof. One such factor is the topography of your area; as lightning is often attracted to high points, a property that’s placed in hills or flatlands are more likely to be hit by lightning strikes compared to properties placed in the low-lands. The frequency of lightning storms in your area can also influence the likelihood of lightning striking your home.
Apart from the topography of your area and frequency of lightning storms, the size and expanse of your building can also decide how likely it is for lightning to strike your property. According to experts, the taller and more expansive your property is, the more likely it is for lightning to strike it, regardless of whether or not you have a metal roofing system attached to the property. Thankfully, experts say that buildings aren’t always struck by lightning often and as such, you should be safe regardless of your building’s size or expanse.
Finally, your building’s proximity to other geographical features can also influence how likely it is for lightning to strike your property. For instance, if your building is smaller than the geographical features that surround it such as trees, then it’ll be the least likely target during a thunderstorm. On the other hand, your building is the tallest building in the area, then it might become the target before other lower-profile features.
