5 Metal Roofing Myths (And The Truth Behind Them)

Misconceptions tend to persist in society, with myths being passed down through generations, clouding the truth. The realm of construction, particularly metal roofing, is no exception to these collective beliefs. Such myths can discourage homeowners from exploring the numerous benefits of metal roofs. This article aims to debunk five misconceptions about metal roofing, shedding light on the facts behind these myths.

MYTH #1: Lightning will strike metal roofs.

TRUTH: There’s a widespread belief that metal roofs are lightning magnets due to their conductivity. However, lightning tends to strike the tallest object with a direct path to the ground in its vicinity. Since metal roofs are not grounded, they don’t attract lightning any more than roofs made of other materials. Metal roofing can be safer in the event of a lightning strike because it doesn’t catch fire like some other roofing materials.

MYTH #2: Metal roofs are hot and trap heat in the summer.

TRUTH: Metal directly exposed to the hot Atlanta sun will heat up, however so do other roofing materials. Metal roofing is now made to combat solar heat and UV rays. These are called “cool roofs”. They reflect the heat keeping the home at a comfortable temperature, and the need for excessive air conditioning use.  When the sun does go down, any heat in the roof is quickly dissipated. Metal roofing is quite energy efficient. Secondly, the color of the roof does have an impact on heat. Lighter colors absorb less than darker colors. 

MYTH #3: Metal roofing is expensive.

TRUTH: Metal roofing indeed comes with a higher upfront cost compared to traditional asphalt roofing. However, one must consider the long-term benefits. The specific type of metal roofing chosen can influence the cost, with standing seam roofing being more expensive than corrugated metal. Despite the higher initial investment, metal roofing can last nearly twice as long as asphalt shingles, providing better durability and a longer lifespan. Over time, this makes metal roofing a more cost-effective choice.

MYTH #4: Metal roofs dent easily.

TRUTH: Contrary to the misconception that metal roofs are easily dented, they are built to be highly durable and resilient. Most metal roofing options are designed with a Class 4 Impact Resistant rating, offering excellent protection against hail and other potential impacts. Dents typically occur only under extreme conditions, such as exceptionally large hailstones, usually larger than a golf ball in size.

MYTH #5: Metal roofing can rust easily.

TRUTH: Many believe that metal roofs are prone to rusting, which can compromise their integrity. However, modern metal roofing is treated with protective coatings, such as a galvalume substrate and a painted finish, to prevent oxidation and rust formation. As a result, metal roofs are designed to withstand the elements and maintain their appearance for several decades. Most metal roofing manufacturers offer extensive warranties against rusting for over two decades.

Opting for metal roofing is a wise decision for homeowners aiming to invest in the long-term resilience and durability of their residences. Despite persistent myths, the facts highlight that metal roofs not only offer safety but also prove to be energy-efficient and cost-effective over time.
