What Kind Of Roofing Materials Are Ideal For Lighting Protection?

It is crucial to take the appropriate safety measures to safeguard your property if you reside in a region that frequently experiences lightning storms. One of the most important steps is installing a lightning protection system. But what kind of roofing materials are best for this purpose? 

In this blog post, TC Roofing & Restorations will rank the most common roofing materials from worst to best on their ability to withstand lightning strikes.

Why Is Lightning Prevention Necessary On The Roof?

It all boils down to fire prevention regarding roofing and lightning strikes. A lightning strike might quickly start a fire if the roof is coated in flammable materials like wood or petroleum-based asphalt shingles.

Lightning generates a high intensity of heat, which can frequently start fires on the roof or within the home after “jumping” from the roof to the next ground level.

Best To Worst Roofing Material For Lightning:

1. Metal Roofing:

A conductive substance, like metal roofing, is what you want for the best lightning protection. Contrary to popular belief, conductive metals don’t draw lightning but provide an electrical channel when a strike occurs. Lightning that hits a metal roof penetrates through the panels and down into the building’s base.

 Almost all metal roofing systems have a Class A fire certification and can withstand just about anything Mother Nature can throw at them.

2. Concrete And Clay Tiles:

Look for fire resistance if conductivity can’t be established throughout the roof. A direct or close lightning strike can disrupt your home’s electrical system and harm electrical appliances, but the possibility of a fire from the heat of the hit is much more harmful to the building. 

Concrete and clay tiles are naturally fire-resistant. When these tiles are used with a lightning protection system, even a direct hit to the roof has minimal possibility of igniting a fire. Additionally, these tiles are less likely to be lifted and thrown off the roof by the strong winds that sometimes accompany thunderstorms.

3. Slate Tiles:

Slate is naturally fire-resistant, making it one of the best roofing materials to withstand lightning. Slate roofs have been known to endure more than a century. While they are among the most expensive roofing options up front, they save money in the long run due to their durability.

4. Asphalt Shingles:

Asphalt shingles are one of the most often used roofing materials. They are also one of the worst when it comes to lightning protection. This is because they are flammable materials that can easily catch fire from a lightning strike. If you live in an area such as Fort Worth, TX, where lightning storms are common, it is important to avoid using asphalt shingles on your roof.

5. Wooden shingles:

A wood roof is among the worst options regarding fire resistance. Wood must be extensively treated with a fire-retardant to attain a Class B or Class A fire rating because it is a flammable material. Even after being treated with fire-retardant, insurance companies normally won’t cover homes with wood roofs in wildfire regions, so if you live in one, you should steer clear of a wood roof.
