Busting Common Myths About Metal Roofing

Metal roofing has gained popularity in both residential and commercial settings due to its many advantages, including durability, longevity, and energy efficiency. However, several misconceptions surround metal roofs that can mislead potential buyers. In this article, we aim to debunk five prevalent myths associated with metal roofing to help you make an informed decision when considering this roofing option.


Myth 1: Metal Roofs Attract Lightning

One of the most enduring myths about metal roofs is that they attract lightning. In reality, lightning is highly unpredictable and primarily determined by weather conditions, not the roofing material. Metal roofs do not have a higher propensity to attract lightning strikes than other roofing materials. Moreover, metal roofs offer an advantage as they are non-combustible, reducing the risk of fire compared to materials like wood or shingles.


Myth 2: Metal Roofs Are Noisy During Rainstorms

Another common misconception is that metal roofs generate excessive noise during rainstorms. The noise level largely depends on the building's construction and insulation. While metal roofs on open-framed structures may produce some noise, residential homes with proper insulation and attic spaces often experience noise levels similar to or quieter than other roofing types. Roofing installers can provide guidance on minimizing rain noise if it concerns you.


Myth 3: All Metal Roofs Develop Red Rust Over Time

While it is true that many metals can oxidize and develop rust when exposed to oxygen and water, not all metal roofs turn red. For instance, copper develops a protective patina that can be bluish-green or dark bronze, depending on location and other factors. Zinc forms a protective patina called zinc carbonate, which resists corrosion. Aluminum does not develop red rust; instead, it forms a white rust that blends with its color. Steel is the primary metal roofing material that can develop red rust, but modern coatings like galvalume are designed to mitigate corrosion.


Myth 4: Metal Roofs Dent Easily

Some individuals worry that metal roofs are susceptible to denting, especially during hailstorms. In reality, metal roofing systems engineered for impact resistance can withstand hail. Roofs with a UL2218 Class 4 rating, in particular, are highly resilient against hail damage. While larger hailstones can potentially cause dents, this risk exists with any roofing material.


Myth 5: Metal Roofs Hold Heat in the Summer

Many believe that metal roofs retain heat in the summer, leading to uncomfortably warm interiors. However, advancements in technology have given rise to cool metal roofing. These roofing panels are highly emissive and reflective, allowing them to release absorbed heat quickly and absorb less heat initially. Consequently, cool metal roofs help maintain comfortable indoor temperatures.


Conclusion:

Dispelling common myths about metal roofing is crucial in making well-informed decisions regarding your roofing needs. By addressing these misconceptions, we underscore the numerous benefits of metal roofing, such as its resilience, impact resistance, and energy efficiency. When contemplating roofing options, consult with professionals and reputable installers to ensure you select the most suitable roofing solution for your property. Metal roofing offers enduring protection and peace of mind for years to come.
