It is vital to remember that Weathering Steel does intentionally rust. It is designed to allow the outer layer of steel to intentionally rust, helping to protect the inner layer of steel. Weathering Steel: This variety of steel was originally used in heavy steel industries like bridge construction. However, this metal roof is vulnerable if scratched and at cut edges. Galvalume steel also provides a smaller, smoother spangle for a more uniform appearance. Aluminum better protects against corrosion in specific environments when compared to Galvanized steel. However, rather than using a primary zinc coating, Galvalume steel uses a combination of Aluminum and Zinc. Galvalume Steel: This type of steel is similar to Galvanized steel. Galvanized Steel is the most commonly used metal when installing a metal roof. The coating on top of the steel helps extend the life of the steel panel and slow the corrosion process. Galvanized Steel: This type of steel is created using a layer of Zinc to protect an inner layer of steel from corrosion. Three primary types of steel are available for roofing: Galvanized, Galvalume, and Weathering Steel. Steel roofing also offers an average lifespan of 40 – 70 years.

This rapid reaction is also what protects aluminum roofs. Due to that, aluminum roofs almost instantly react to atmospheric conditions. The reality is that aluminum is a highly active and reactive metal. While the common perception is that aluminum roofing is not affected by any corrosion, this is untrue.
