This is perhaps the biggest myth about metal roofing. While metal is a conductor of electricity, it does not draw electricity. Lightning is an excess of electricity in search of the nearest possible discharge. It will strike the tallest object in the area, like treetops or a power pole.
A metal roof poses no additional risks of a lightning strike. As a matter of fact, as a non-combustible material, metal roofs are a smart option for lightning-prone regions. A metal roof disperses electricity from lightning safely through the structure of your home. If an asphalt roof gets struck by lighting, there's a potential for a fire.
