Nowadays, roof and siding contractors offer various roof covering options that can suit just about any homestyle or aesthetic look. If you want an old and rustic vibe, you can always pick wood shake. On the other hand, if you want the traditional American appeal, you can go for multi-colored asphalt shingles. However, there is one material that is extremely popular in many areas of construction, including home improvement, and that is the metal roof. 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.
Do You Need to Ground Metal Roofs?
In simple terms, the answer is no. Metal roofing is safe and you won’t incur additional risks if you don’t ground it in most circumstances. Even though metal conducts electricity, a full roof can manage to ground out a lightning strike through the rest of the building without causing damage to the interior and occupants. In addition, most metals are inflammable in nature, meaning that you’ll be safer should the rare chance of a lightning strike happen.
Currently, there’s no specific building requirement in the National Fire Protection Association’s building codes guide that calls for a ground on a metal roof. So in case roofing and siding companies don’t ground metal roofs during installation, this is your answer.
Do Metal Roofs Attract Lightning?
When it comes to grounding a metal roof, this particular question is usually the instigator. The truth is, metal roofs don’t attract lightning. Lightning will strike an item or material that gives the least resistance as a path to the ground. Since a metal roof provides the same path as a standard roof on the same structure, it won’t pose a greater risk of a lightning strike.
However, keep in mind that roofing contractors can only use PVC piping to extend from the interior of the house up through the roof. If a metal pipe is used, the would not be grounded enough and instead could travel down the pipe inside the home and cause damage.
