Should Metal Roofs Be Grounded
We elaborate further in this post.
Should metal roofs be grounded. Metal conducts electricity but when you are dealing with a full roof a lightning strike would ground out through the rest of the structure without causing damage or harm to the interior. Metal roofing is perfectly safe. If you plan on using metal roofing you may need to consider whether or not you need to ground that roofing like other metal equipment in construction. The short answer is no you don t have to ground a metal roof and you will incur no additional risk if you don t ground it in most circumstances.
In simple terms the answer is no. Do you need to ground metal roofs. Do you need to have your metal roof grounded. Wouldn t a grounded metal roof protect your home.
Nor do metal roofs protect a building against lightning. No in fact the best thing you can do for your own personal safety during a thunderstorm is to head indoors. It does not attract any extra attention from lightning and just like buildings constructed with traditional building materials any electricity from a lightning strike will will be safely transferred to the ground below so occupants will be unaffected. Metal roofs do not attract lightning strikes.
Metal roofing is safe and you won t incur additional risks if you don t ground it in most circumstances. What if lightning struck your roof. In general there s no need to unless it s mandated by your local building codes. In the case of a metal roofed building any electricity from a lightning strike will be safely transferred to the ground below so occupants will be unaffected.
The only way to protect a building is with a properly designed and installed lightning protection system lps. A metal roof in no way makes your home more vulnerable or susceptible to lightning strikes. Metal roofs are resistant to wind and hail weigh less than asphalt shingles require little maintenance and are energy efficient. Your metal roof is not grounded and thus lighting has no reason to strike it.
