Metal Roofing Myth: Is It True That All Metal Roofs Eventually Rust?

We’ve come a long way since the days that metal roofs were reserved for use on a certain type of building. Time was, you would only see a metal roof on an agricultural or industrial building than you would anywhere else.

We’ve come a long way since then, and now we know that metal roofs have a lot to offer. The durability, strength and life span of metal roofing makes it a perfect choice for virtually any type of building.

Additionally, you can get metal roofing in such a wide variety of  colors, styles and finishes that they’ll look right at home on even the most reserved residential property.

Despite all of the positives, however, there are still people who believe that metal roofing isn’t a good match for their property at all. Often, the reason for this is that they believe one of the myths about metal roofs that have no real basis in reality.

People have worried that metal roofs are more likely to be struck by lightning, or that they make the rain sound unbearably loud when it rains, even though neither of these have any real truth to them at all.

To help you get to grips with what the truth is, we here at Garvin Metal Roofs New York have decided to get to the bottom of one of the more common concerns we’ve heard about metal roofing:

The grain of truth in this myth comes from the time when metal roofs were mainly found on barns and sheds, and were just sheets of metal roughly hammered onto the buildings. Given these conditions, it is no wonder the metal roofs of old were subject to rust and corrosion.

These days, metal roofs are a lot more technologically advanced. This means that you won’t have to worry about any rust or corrosion affecting your roof for a long time. The metal sheets that make up roofing panels are coated and treated to help prevent rust formation.

For example, treating a steel roof panel with a zinc compound allows it to develop a layer of zinc hydroxyl-carbonate that naturally acts to prevent moisture from getting through to the metal, making it naturally resistant to corrosion and rust.

Additionally, if you choose a metal roof that is constructed out of aluminum, then you won’t have to worry about red rust at all. Instead, aluminum develops a white rust that can simply blend in with the

This is part of the reason why metal roofs are so incredibly strong and long lasting, In fact, you can expect your average metal roof to last you at least twice as long as traditional asphalt or shingle roofs.
