Grounding Myths for Metal Roofs: A Perspective from Classic Metal Roofs, LLC


As a leading metal roofing provider in Southern New England, Classic Metal Roofs, LLC is committed to delivering durable, energy-efficient, and long-lasting roofing solutions. A common misconception is that metal roofs require grounding. This is a practice that’s not typically necessary for residential roof installations.


The Myth of Grounding Metal Roofs

Contrary to popular belief, residential metal roofs generally do not need to be grounded. While metal is a good conductor of electricity, the risk of electrical hazards such as lightning strikes is not inherently higher with a metal roof than with other roofing materials. In fact, properly installed metal roofs present no greater risk of attracting lightning than other types of roofs.


When Grounding Might Be Considered

Lightning typically seeks the highest point in the landscape, which is usually not defined by the roofing material but rather by the height of the structure relative to its surroundings. Metal roofs do not inherently increase the likelihood of a lightning strike compared to other types of roofs. 


In fact, if a metal roof does happen to be struck by lightning, its conductive properties can help safely dissipate the electrical energy across its surface and into the ground, reducing the risk of fire or structural damage. This characteristic can actually make metal roofs a safer option in the event of a storm. It’s important to ensure that any structure is properly equipped with a lightning protection system, especially in areas prone to frequent thunderstorms. 


Overall, metal roofs, when properly installed and maintained, offer excellent protection and durability without increasing lightning-related risks. 


The caveat would be if the house is the highest point on a hill with nothing around it or in an open field.


How Grounding Would Be Implemented

In rare cases where grounding might be considered, connecting grounding conductors like copper or aluminum cables to designated grounding rods will get the job done. This method creates a safe pathway for any potential electrical surge, although it is typically redundant for residential structures.

According to John Brady in Clavis Calendaria, the Dog Days were believed to be a time when “the sea boi...
