Do Metal Roofs Attract Lightning?

Metal is becoming increasingly popular as a roofing material due to its durability, endurance, and energy economy. However, many homeowners are concerned about, ‘Do metal roofs attract lightning?’.

To satisfy your quest for ‘Do metal roofs attract lightning?’, Only Roofing Woodlands TX reveals the science underlying lightning strikes and dispels the myths about the relationship between metal roofs and lightning.

What Happens If Lightning Hits Metal Roof?

A lightning strike will not burn through a metal roof. Like the metal lightning rod, it disperses the lightning’s strength, cushioning the damage. In contrast, a tall tree struck by lightning can readily catch fire, burn, and smoke for hours.

Metal Roofing and Conductivity

The conductivity of metal roofs is one aspect that contributes to the belief that they attract lightning. Metals are great electrical conductors, and it is simple to imagine a metal roof acting as a magnet for lightning. However, this assumption simplifies the complex mechanics of lightning strikes.

Contrary to common opinion, metal roofs are not considerably more likely to be struck by lightning than other types of roofing. Tall structures, trees, and geographical factors are more likely to attract lightning than the roof itself.

Height Matters

The structure’s height is the critical element impacting the chance of the structure’s strike. Tall things, such as buildings and trees, are more likely to be struck by lightning because they are close to the charged clouds.

In contrast, regardless of roofing material, single-family dwellings are shorter and less prone to attract lightning.

Lightning’s Path of Least Resistance

When lightning strikes a building, it takes the route of least resistance to the earth. Due to their conductivity, metal roofs are better suited to channeling electrical currents securely to the ground. This trait is advantageous since it reduces the potential harm caused by a lightning strike.

The Bottom Line

Summarizing, ‘Do metal roofs attract lightning?’, the belief that metal roofs attract lightning is more myth than fact. The chance of a lightning strike is determined more by a structure’s height and surroundings than by the roof material. You must be confident that well-maintained metal commercial roofing is a long-lasting and energy-efficient option for your properties!
