Metal roofs have become a popular choice among homeowners. They offer a long list of benefits, including superior weather resistance, energy efficiency, and a long lifespan. They also come in a variety of styles and colors, making them suitable for just about every type of home. But, one concern raised by a lot of homeowners is whether or not a metal roof will rust.
Metal Roofs and Rust
There are a lot of different types of metals like aluminum, copper, and steel that you might find used in metal roofs. But only metals containing iron, such as steel, are susceptible to rust.
Aluminum is one of the most popular materials used for metal roofs. It is one of the most abundant metals in the world, is lightweight, durable, recyclable, and naturally rust-resistant.
Copper and tin don’t contain iron, so they are also naturally rust-resistant. But both of those materials are susceptible to tarnishing, particularly in coastal areas.
Just because steel contains iron, that doesn’t make it a terrible choice for a metal roof. As long as you are using galvanized steel, the protective coating on the material will prevent rust and oxidation.
Protecting a Metal Roof from Corrosion and Rust
No matter what material you choose for your metal roof, it’s never a bad idea to give it extra protection from corrosion and rust. Here are a few options:
Aluminum
You can coat a metal roof, such as one made of steel, with aluminum. This prevents the material from rusting by giving it an added layer of protection from the elements.
Zinc
Also known as galvanization, steel can be coated with a layer of zinc oxide to make it resistant to rust. This type of treatment is long-lasting and requires little maintenance.
Zinc, Silicon, and Aluminum
You can also combine zinc and aluminum together with silicon to coat a steel roof. This type of coating is known as galvalume. It provides superior rust protection for metal roofs, particularly in coastal areas.
Maintaining Your Metal Roof to Prevent Rust
Steel is a superior material for all types of metal roofing applications. But, you’ll want to make sure your metal roof has been treated with a rust-resistant coating if you choose this material.
The coating applied during manufacturing may need to be re-applied after about 5-10 years. When your roofing manufacturer inspects your roof each year as part of your regular maintenance, they will determine if the protective coating needs any attention.
