Metal roofing myths: Separating fact from fiction

Metal roofing has become increasingly popular among homeowners for its durability, energy efficiency, and sleek design. However, several myths can make people hesitant to choose this roofing material.

I will explore the most common metal roofing myths and clarify misconceptions about noise, rust, and other concerns.

Myth 1: metal roofs rust easily

Modern metal roofs are designed to resist rust. They are typically made from aluminum, galvanized, or coated steel, including protective layers to prevent oxidation.

For instance, galvanized steel roofs are coated with zinc, while aluminum naturally resists corrosion. Additionally, most metal roofs are finished with durable paints or coatings, such as Kynar, which protects them from moisture.

This myth arises from old metal roofs without the advanced coatings and materials used today.

Myth 2: metal roofs are noisy

When installed correctly, metal roofs are no noisier than asphalt shingles. Proper installation involves a solid underlayment and insulation that dampens sound. These layers help absorb rain or hail impacts, making the noise level comparable to traditional roofing materials.

Popping noises are rare but can occur due to thermal expansion and contraction as the roof heats and cools. However, skilled installation minimizes this by allowing natural movement within the roof system.

Myth 3: metal roofs are too expensive

While the upfront cost of a metal roof is higher than asphalt shingles, it’s a long-term investment. Metal roofs can last 40 to 70 years, whereas shingles typically need replacement every 20 to 30 years.

Their durability, energy efficiency, and low maintenance make them cost-effective in the long run.

Myth 4: metal roofs attract lightning

Metal roofs do not attract lightning. Metal is a non-combustible material, meaning it is safer in the event of a lightning strike. Lightning is more likely to strike the tallest object in an area, regardless of its material.

Myth 5: metal roofs are heavy

Metal roofs are one of the lightest roofing materials available. They are lighter than asphalt shingles, slate, and tile roofs. This reduced weight makes them easier to install and places less stress on your home’s structure.

Myth 6: metal roofs don’t work well in cold climates

Metal roofs perform exceptionally well in cold climates. Their smooth surface allows snow and ice to slide off easily, preventing ice dams. Additionally, metal roofing systems can be paired with snow guards to control snow movement, protecting gutters and landscaping below.

Myth 7: metal roofs look industrial and boring

Modern metal roofs come in a wide variety of styles, colors, and finishes. They can mimic the look of traditional shingles, slate, clay tiles, or even wood shakes. This versatility allows homeowners to achieve the aesthetic they desire without sacrificing the benefits of metal.

Myth 8: metal roofs can’t be walked on

You can walk on a metal roof, but you need to step carefully to avoid denting or damaging the surface. Walking on a metal roof is safe with proper support and knowledge of where to step (usually on the ribs or over support structures).

Myth 9: metal roofs are hard to repair

Metal roofs are designed for durability, but repairs are straightforward if necessary. Damaged panels can often be replaced individually without disturbing the surrounding roof system, making repairs less invasive than other materials.

Myth 10: metal roofs don’t work with solar panels

Metal roofs are one of the best roofing materials for solar panels. They provide a stable surface for panel mounting and often last longer than the solar panels’ lifespan, eliminating the need for re-roofing during the panels’ use.

Metal roofing myths often arise from outdated perceptions or a lack of understanding about modern roofing technology. With their durability, energy efficiency, and wide range of design options, metal roofs are an excellent choice for homeowners.
