Static Buildup And Lightning With Metal Roof

Static buildup and lightning with metal roof.

This is just one more reason why we at schroer sons believe a lifetime metal roof is the best roof available today. Metal roofs do not attract lightning. Crouching doesn t make you any safer outdoors. During a voltage surge caused by a lightning event accidental power contact power cross or static buildup caused by wind or blowing snow the adu clamps the voltage on the lead in to some maximum value typical values range from 90 to 240 v and diverts the resulting current to earth ground via the bonding and grounding electrode conductors.

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. Run to a substantial building or hard topped vehicle. 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. A metal roof does not attract lightning.

Tall buildings farmhouses and other structures susceptible to lightning strikes are often equipped with lightning rods. A more common problem is static build up from electric charge in the air during a lightning storm. If your home is struck by lightning a metal roof will diffuse electricity away and cannot catch fire keeping your home safer in a thunderstorm. If you are too far to run to one of these options you have no good alternative.

A metal building may survive a lightning strike with less damage than a similarly sized and located building made of higher resistance materials. Metal roofs and lighting the misconception that metal roofs attract lightning is probably because metal itself is known as a good conductor of electricity and people therefore assume that a metal roof must attract lightning. The metal construction association notes that metal roofs do not attract lightning. Lightning myths and facts.

A metal building system with a conductive metal roof and a conductive metal structural frame gives lightning a low resistance path to the earth. Surprisingly one of the main fears people hold about metal roofs is without merit. This static can cause a charge to run down the cables from the roof and damage equipment in your house. Metal roofs are no more attractive to lightning than any other type of roofing material.
