Metal roofing has increased in popularity over recent years, and for good reason. They offer a number of benefits, which includes durability, longer lifespan, energy efficiency, and low maintenance. They are also pest and fire-resistant, and you can choose from a variety of styles and colors to match the rest of your home.
One of the most common questions that we get asked at ABC Roofing is whether or not metal roofing will rust.
Will My Metal Roofing Rust?
This is entirely dependent on two main factors: What type of metal your roof is and whether or not it has been treated. Let’s look at these two factors.
Types Of Metal And Rust
There are three main types of metal roofing; steel, aluminum, and copper. All three have different levels of resistance to rust.
– Steel is the most popular type of metal roofing and is often what people think of when they picture a metal roof. It is strong and durable, making it a great choice for homes in areas with severe weather conditions. It is also the most affordable option. However, it is also the most likely to rust. This is because steel is a ferrous metal, which means it contains iron. When iron comes into contact with water and oxygen, it corrodes and turns to rust. The good news is that this can easily be resolved with the right treatment.
– Aluminum roofing is a non-ferrous metal, which means it does not contain iron and is therefore resistant to rust. It is also lightweight, making it easy to install, and is a popular choice for those who are looking for an eco-friendly option as it is 100% recyclable. The only downside of aluminum roofing is that it can be more expensive than steel, but if you are looking to invest in your roof then this may be the option for you.
– Copper roofing is the most expensive option, but it is also the most durable and has the longest lifespan. This is because copper is a natural element that is found in the earth’s crust and does not corrode when it comes into contact with water or oxygen. It is also known for its antimicrobial properties, which means it can help to protect your home from bacteria and mold.
Protecting Your Roof With The Right Treatment
Now that we know the types of metal roofing and their resistance to rust, let’s look at how you can protect your roof with the right treatment. There are a number of protecting coatings that will protect your metal roof from corrosion and rust.
Before we go into each, it is important to note that you should have your roof installed by a professional if you want to avoid rust. This will ensure that it is properly sealed and that all seams are correctly fastened.
1) Zinc
Zinc is often used as a protective coating for steel roofing. Known as galvanization, by coating a roof with zinc oxide it will become rust-resistant. What’s great about galvanization is that it’s long-lasting, often lasting for up to 50 years.
2) Aluminum
As we mentioned above, Aluminum is highly resistant to rust. Often roofing professionals coat steel with Aluminum to protect it from the elements. It’s an effective method of preventing a roof from rusting.
3) Combining Zinc And Aluminum With Silicon
It is also possible to combine zinc and aluminum with silicon to create an even more effective barrier against rust. This process is known as galvalume, which was patented in 1972 by Bethlehem Steel. It gives a roof excellent protection against rust, especially in coastal areas.
How Often Should You Reapply A Coating To Your Roof?
It really depends on the type of metal roof you have and your location. Coastal areas are more susceptible to rust and would require reapplication more often than roofs that are more inland.
Generally, it is recommended that you reapply a coating to your roof every five to twelve years. This will ensure that it remains in good condition and does not rust.
Trust The Roofing Professionals
When it comes to protecting your roof from rust, it is always best to trust the roofing professionals. They are able to advise you on the best type of coating for your roof and how often you should reapply it.
