Lightning And Metal Roofs

Then the metal s fire resistant properties will protect your building even further.

Lightning and metal roofs.

Should your metal roof be struck by lightning the electricity will be spread out across a larger area which diminishes the immediate impact. The metal construction association notes that metal roofs do not attract lightning. Steel roofing materials are no more attractive to lightning than any other type of roofing material according to the metal roofing wholesalers website. Metal clearly is far more resistant to fire than asphalt shingles wood shingles or other shingle 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. It is a false belief that metal roofs can increase the risk of a lightning strike. 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. Fire is the most destructive element of a lightning strike because most roofs will immediately combust.

In other words metal roofing does not affect the chances of lightning discharging from the sky and striking structures. A metal building system with a conductive metal roof and a conductive metal structural frame gives lightning a low resistance path to the earth. In fact as a non combustible material with the highest class a fire resistance rating metal roofing is the most desirable material for homes and businesses in lightning prone regions. In this regard metal building materials far exceed traditional wood framed buildings due to metal s non combustible nature.

Metal roofs are no more attractive to lightning than any other type of roofing material. Lightning is attracted to. In fact the most destructive part of a lightning strike to a building is the fire it produces. Regardless if a suburban area has metal roofs or not lightning will strike whenever it is ready.

Even so metal roofs do not attract lightning and are not struck any more frequently than other roofing materials. A metal building may survive a lightning strike with less damage than a similarly sized and located building made of higher resistance materials. 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.
