People still have many outdated ideas about metal roofs, and most of those ideas were passed around so often that nobody stopped to check if they were true. Some believe these roofs make a loud noise during rainstorms, while others worry they’ll attract lightning, rust quickly, or trap heat inside the house.
But metal roofing has changed significantly enough that many of these fears or doubts no longer make sense. With modern materials and installation methods, metallic roofs now offer benefits that go far beyond what people expect from shingles or tiles.
In fact, the global metal roofing market was valued at $22.55 billion in 2024, and it’s expected to grow steadily, reaching $32.83 billion by 2032, with an average annual growth rate of 4.81% from 2025 to 2032 (source). This clearly shows just how many homeowners are rethinking their roofing needs.
Let’s go through the biggest myths and break down what’s actually true.
Myth 1: Metal Roofs Attract Lightning
Many people still believe that these roofing solutions increase the chance of being hit by lightning, but this idea doesn’t hold up under science. Lightning strikes the highest point in an area, not the most metallic surface, so the material on your roof doesn’t make your home more of a target.
In fact, having a metal roof could make your home safer during a lightning strike. Metal conducts electricity and disperses the energy across the surface, lowering the risk of fire or structural damage.
Myth 2: They Are Noisy in the Rain
One of the most popular myths regarding metallic roofs is that they make excessive noise during rain or hailstorms. This idea derives from the old-fashioned tin roofs seen in barns and sheds, which can be rather noisy. However, sophisticated roofing techniques have developed.
Modern metal roofs are built with strong sheathing and insulation, which greatly minimizes noise. These layers function as sound barriers, absorbing and suppressing the sounds of rain, hail, and other weather-related noise. When placed correctly, these roofs may be quieter than regular asphalt shingles.
Myth 3: These Roofs Rust Easily
Contemporary metallic roofing materials are designed to withstand rusting and corrosion even in harsh climatic conditions. Furthermore, these roofs now have superior surface coatings, resulting in increased durability and lower maintenance requirements during their lifetime. Routine inspections and maintenance done by professional metal roof repair contractors may help extend the life of this roofing solution, assuring long-term performance.
Myth 4: Metal Roofing Makes Homes Hotter Inside
It’s understandable to believe that a metallic roof would make your home hotter in the summer, yet this is not true. Metal roofing in Houston, TX, is one of the most energy-efficient roofing options on the market. In contrast to asphalt shingle roofs, which absorb heat like a sponge, metal roofs reflect solar radiation upward and away from the dwelling. During the hot summer months, you may notice warnings about how asphalt may heat up to 50 degrees higher than the surrounding air temperature.
Asphalt shingles are among the worst alternatives for energy-efficient roofing due to their low emissivity and poor solar reflection. Metallic roofs, on the other hand, are intrinsically reflective, reflecting most of the sunlight. Because metal reflects energy up and away from the structure, less heat is absorbed, keeping the residence colder.
