Rustic design has a natural and aged look that has gained popularity in recent years in architectural and interior designs. When it comes to roofing, a rustic appearance can be achieved with the use of steel that arrives unrusted and will rust with exposure to the weather or with painted panels that look rusted.

At Western States Metal Roofing, we manufacture rusted metal roofing and siding panels in Corten Steel and bare cold rolled steel that will naturally rust. Even though both products have similar appearances and chemical compositions, they do have differences. In some cases, neither Corten or bare steel may actually be the right fit for your project. In those cases, using painted metal panels that are designed to look like weathering steel would be a better option.

In this article, we discuss the pros and cons of rusted metal roofing and when using painted metal panels may be a better fit to help you decide which to use on your project.

 

What Is Rusted Tin Roofing?

A rusted tin roof is a metal roof where the panels have developed a protective oxide coating on the surface over time which gives the roof a rusted orange color and appearance that is always slightly unique, giving each rusty metal roof its own aesthetic that is one-of-a-kind. While people use the term “tin roof”, the roof is actually made from a different type of metal: steel. Traditional tin roofs are no longer used and have been replaced by aluminum or steel.

The patina can slow down the overall rate of corrosion. In addition to this important function, rusted tin roofing is also popular for its appearance. The antique and natural look of metal roof rust especially blends well with desert, farmland, and mountain areas. However, it's not the right choice for all areas.

 Rusted tin roofing is not compatible in climates, including tropical and coastal areas, as the salt spray from the ocean prevents the development of the inner protective oxide layer from forming.

Corten Steel

Bare Cold Rolled Steel

Corten Steel

Corten steel has a natural oxidizing finish that not only looks attractive, but also alloys that will decrease the rate of corrosion.

Superior Corrosion Resistance Compared To Bare Cold Rolled Steel

Corten is also referred to as weathering steel or A606-4. It contains a combination of copper, chromium, manganese, and nickel. After the surface rust has developed, the composition of Corten gives it superior corrosion resistance and a greater ability to handle harsh climates compared to bare cold rolled steel.
