5 Metal Roofing Myths and the Truth Behind Them

Believing myths can blind us to the truth”. This paraphrased version of a quote by Jawaharlal Nehru, the first Prime Minister of India, holds profound significance. Not only in various aspects of life but especially concerning the misconceptions surrounding metal roofing. Here are five prevalent misunderstandings about metal roofing and shed light on the truth behind each of them.

MYTH #1: Metal roofs attract lightning strikes.

TRUTH: A common belief is that metal roofs are more likely to attract lightning due to their conductivity. However, lightning typically strikes the tallest object in its vicinity with a direct path to the ground. Since metal roofs are not grounded, they do not attract lightning any more than roofs made of other materials. In fact, metal roofing is safer in the event of a lightning strike, as it does not catch fire like some other roofing materials.

MYTH #2: Metal roofs are excessively hot and retain heat in summer.

TRUTH: There is a misconception that metal roofs become unbearably hot under the scorching sun, but this is not unique to metal roofing alone. Modern metal roofing incorporates “cool roof” technology to combat solar heat and UV rays effectively. These cool roofs reflect a significant portion of the heat, maintaining a comfortable temperature inside the house and reducing the need for excessive air conditioning. Additionally, any accumulated heat in the metal roof dissipates quickly as the sun sets. Furthermore, the color of the roof also plays a role in heat absorption, where lighter colors absorb less heat compared to darker ones.

MYTH #3: Metal roofing is expensive.

TRUTH: It is true that metal roofing 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 are prone to denting.

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. Generally, dents only occur under extreme conditions, such as exceptionally large hailstones, usually larger than a golf ball in size.

MYTH #5: Metal roofing is susceptible to rusting.

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 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.
