Do Metal Roofs Rust?

2 min read

Metal roofs are one of the most sought-after roofing options on the market. Homeowners and commercial property owners love metal roofs for their durability, long-lasting performance, and longevity. Metal roofs are often misunderstood as rusting. Let’s look at how to protect and treat your metal roof panels from rust.

Do Metal Roofing Rust?

Metal roofs can withstand oxidation for most of their lifetime thanks to advances in paint systems, finishes, and other technologies. Many factors can influence whether your roof rusts. Plain, unpainted steel, for instance, will rust. If the edges of your panels don’t get appropriately cut, they could rust.

Rust-Resistant Technology

Metal roofing panels are metal and coated with high-quality paints and finishes. They are then tested to ensure that they are resistant to rust. These are the most common coatings and steel types that are rust-resistant.

  1. Galvalume Steel: Galvalume steel is a coating that is applied over steel. It’s made of aluminum, zinc, and silicone, providing corrosion and rust resistance. This coating is ideal for protecting your roof against corrosion if you live in high-temperature, high-precipitation, or marine environments. Galvalume has a matte finish.
  2. Galvanized Steel: Galvanized is steel made from carbon steel and zinc oxide. The zinc coating protects the panels and keeps them in place for decades. The final look of galvanized steel is finished with a resin coat that gives it a shiny, smooth finish and resists scratching.
  3. Weathering Steel: Weathered Steel can rust up to a point and is an incredible option for steel roofs. It is finished with a layer of copper, silicon, and phosphorus. Once exposed to the elements, it will begin to rust. The steel ionizes once the top coat is removed. This means the steel doesn’t corrode further, and the panel won’t rust. This option is not meant to rust and will last just as long as other finishes.
