If you are considering a metal roof but have concerns associated with rust, you are not alone. Installing a metal roof may make you feel apprehensive about its durability and sturdiness in the longer run. As a homeowner, you will always want to invest in a type of roof that will last for years. 

When installed by a professional roofer, metal roofs can last for more than two decades. Being made of different types of metal, these roofs offer varying resistance to corrosion. Some types of metal naturally resist corrosion, while others need protective coatings to prevent rust. 

When the context is about selecting a long-lasting roof, you just cannot look beyond metal roofs. Metal roofs offer you a range of benefits, including longevity and aesthetic appeal. The most concerning myth commonly believed by homeowners is that metal roofs can rust over time. 

Let’s explore the factors associated with rusting and the types of metal roofs available in the market. 

What is Rust?

Rust refers to a type of corrosion on a metal surface. When metal is exposed to oxygen and moisture for extended durations, rust can form. Note that rust is commonly associated with steel and iron. Usually, metal roofs are made from steel, aluminum, copper, and zinc. Each of these metals can resist rust differently. 

Rust Formation on Aluminum and Steel Surfaces – Essential Aspects to Know 

It is pretty normal for you to have concerns about rust when considering a metal roof. Steel is an integral part of metal roofs and contains iron. When exposed to water and oxygen, iron can rust. When you leave the metal roof unattended, rust can spread across the entire structure. 

Thanks to the recent advancements in paint systems and metal finishes, metal roof surfaces can withstand rust. For steel panels on roofs, a metallic coating of zinc is applied, which safeguards it from rust. If you are considering installing a steel roof, ask the roofer to coat the surface with zinc. 

Zinc exhibits strong anticorrosion properties and bonds well with other metals. Besides steel, metal roofing panels can also be made of aluminum. You should consider installing an aluminum roof as it reflects light and cools your space effectively.
