Metal Roofing Myths: Don’t Believe Everything You Hear About Metal Roofs


Uncover the reality behind the common metal roofing myths! Trust the Auckland expert metal roofers at Johnson Roofing now. Continue reading to learn more!

Metal roofing is becoming an increasingly popular choice for Auckland homes and buildings. Metal is lightweight, durable, energy-efficient, and stylish. However, some stubborn myths continue swirling about metal roofs. Don’t let misconceptions keep you from considering metal for your next Auckland roofing project. Below, we debunk some common metal roofing myths.

Most Common Metal Roofing Myths

•  Myth 1: Metal Roofs Attract Lightning and Are Unsafe – This is perhaps the most prevalent and persistent myth about metal roofs. In fact, metal roofing is no more likely to be struck by lightning than other roofing materials like asphalt shingles. Lightning strikes based on the height of the structure and nearby conductive objects, not the roofing material itself. Properly grounded metal roofs offer good lightning protection by providing a conductive path for electricity to flow to the ground. The metal construction also allows for quick dissipation of lightning energy across the roof’s surface. Quality metal roofing from companies like Johnson Roofing meets strict standards for lightning protection.

•  Myth 2: Metal Roofs Are Noisy in Rainstorms – There’s a perception that heavy rain on a metal roof creates loud noise inside the home. But today’s advanced metal roofing systems are specially designed to minimise noise from rainfall. Anti-noise insulation, solid sheeting, and protective coatings prevent rain noise. Moreover, you can opt for standing seam metal roofing for Auckland homes, as standing seams scatter the sound of raindrops compared to exposed fastener systems. With the right metal roofing products and professional installation, noise shouldn’t be an issue.

•  Myth 3: Metal Roofs Are Prone to Rust and Corrosion – It’s reasonable to assume metal would succumb to rust over the years, especially in Auckland’s marine climate. But modern metal roofing comes with protective finishes that create an effective moisture barrier. The metals themselves also have corrosion-resistant properties. Reputable suppliers like us use high-quality metals like Colorsteel and New Zealand Steel with long-lasting paint finishes to resist rust. Regular maintenance checks will keep your Auckland metal roof in excellent condition for decades.

•  Myth 4: Metal Roofs Make Homes Hotter and Colder – Since metal quickly conducts heat, there are fears it amplifies summer heat and winter cold inside the home. In reality, properly insulated metal roofing regulates interior temperatures effectively. The reflective nature of light-coloured metal actually helps lower internal heat in summer. And metal’s low thermal mass prevents heat transfer into the home. Come winter, insulation beneath the metal panels retains warmth inside. With good insulation, ventilation and design, metal roofing performs excellently in Auckland’s climate.

Metal roofing has come a long way in terms of aesthetics, technology, durability, and energy efficiency.
