5 Myths About Metal Roofs (And Why They're Dead Wrong)

Metal Roofing Myths Homeowners Still Believe

When it comes to choosing a new roof, misinformation can cloud your judgment and cost you in the long run. Metal roofs have surged in popularity for their longevity, energy efficiency, and low maintenance, but myths still persist. Let's debunk five of the most common metal roofing myths and set the record straight.

1. Myth: Metal Roofs Leak More Than Shingles

This myth stems from poor installation practices, not the roofing material itself. In reality, metal roofs, especially standing seam systems, are designed with interlocking panels that form a tight, watertight seal. When installed by professionals like Valley Metal Roofing, these roofs outperform shingles in leak protection, especially during BC's heavy rain season.

2. Myth: Metal Roofs Attract Lightning

One of the oldest metal roofing myths is that they increase your risk of a lightning strike. The truth? Lightning is attracted to the tallest object in an area, not the material it's made from. And if lightning does strike your metal roof, it actually disperses the energy safely because metal is non-combustible. In that sense, metal roofing could actually be safer than other materials.

3. Myth: Metal Roofs Block Cell Phone Signals

This myth continues to circulate, but it's largely outdated. Modern construction materials—including insulation, concrete, and low-emissivity windows, impact cell signals more than a metal roof ever could. And with today's technology, any minor interference is easily solved with a booster or Wi-Fi calling.

4. Myth: Metal Roofs Are Noisy in the Rain

It might sound romantic in a cabin, but the idea that metal roofs are loud during rainstorms is another misconception. With proper insulation and attic space (standard in modern homes), the sound level is comparable to any other roof. Most Valley customers report no noticeable noise difference compared to their old asphalt roofs.

5. Myth: Metal Roofs Rust Easily

Thanks to modern coatings like Hylar 5000 and Kynar 500, metal roofs are built to withstand even BC’s coastal climates. These coatings prevent rust, fading, and corrosion for decades. Steel and aluminum panels used by Valley Metal Roofing are designed to last over 50 years, with minimal maintenance.
