What is Metal Roofs Made of?

The main material used is steel. For corrugated galvanized steel roofs, a wrought iron-steel sheet is coated with zinc. A blend of zinc, aluminum, and silicon-coated steel is often used for factory coated colored roofs, while stainless steel is the choice material in harsh weather conditions. However, aluminum and copper are also popular metal materials for roofing. 

Aluminum is lightweight and extremely long-lasting, making it a popular material. Copper is more often used for flashing as it is an extremely expensive material. However, the beauty of copper makes it sought out, especially when restoring historical buildings. 


Metals roofs, being lightweight, making them easy to transport. However, they are also extremely durable as the oxidization of the base material forms a protective patina. The lowest end metal roofing can last 20 to 30 years, which is rough twice the lifespan of an average asphalt roof. 

Likewise, coatings used can be designed for particular environmental elements, making the materials that much tougher to resist wear and tear. 

As eco-friendly material, metal roofs are used in what is known as "Cool Roofing." The urban heat island effect is the absorption of heat in urban areas which adds to global warming. They reflect the heat, aiding in reducing atmospheric temperatures. 

Another advantage is the material can easily cover large buildings with less material than other types of roofing, and repairs and maintenance are considerably less in both price and occurrence.
