Metal Roof Lightning

Lightning is attracted to.

Metal roof lightning.

Lightning strikes on metal roofs are an understandable concern for homeowners considering an upgrade to a metal roof. Metal roofs do not attract lightning strikes. The metal construction association notes that metal roofs do not attract lightning. A metal building may survive a lightning strike with less damage than a similarly sized and located building made of higher resistance materials.

While a building s structural steel will conduct lightning it is the bonding interconnection and grounding provided by a lightning protection system lps that will dissipate lightning s harmful electricity safely to the ground. Lightning produces intense heat and often this heat can cause fires on the roof or inside the house. The reality is that a properly installed metal roof may actually be an advantage if a building is struck by lightning. The only way to protect a building is with a properly designed and installed lightning protection system lps.

Even so metal roofs do not attract lightning and are not struck any more frequently than other roofing materials. Metal roofing materials are non combustible so if a metal roof does get struck by lightning it is less likely to result in a fire than some other types of roofing materials such as cedar shakes. The concern about metal roofs attracting lightning strikes is most likely associated with the fact that metal can be an electrical conductor. The concern about metal roofs attracting lightning strikes is most likely associated with the fact that metal can be an electrical conductor.

Even so metal roofs do not attract lightning and are not struck any more frequently than other roofing materials. Nor do metal roofs protect a building against lightning. Lightning is attracted to. Metal is also a non combustible material.

Metal roofs are no more attractive to lightning than any other type of roofing material. A metal building system with a conductive metal roof and a conductive metal structural frame gives lightning a low resistance path to the earth. The materials used in the construction of a metal roof specifically steel are obviously conductive however they do not attract lightning strikes according to the metal construction association. Extensive research on lightning protection reveals that metal roofing is no more likely to attract a lightning strike than any other type of conventional roofing material.
