Understanding Some Of The Pros And Cons Of Choosing An Aluminum Roof

Posted on: 3 August 2017

If you want a metal roof placed on your home, then you may be surprised that there are several options available to you. While steel is often the "go to" material for metal roofing, it is not always the best choice. Aluminum may actually be a bit better for your home. If you want to know about some of the pros and cons of this material, then keep reading. 

Pro - It Is Resistant to Corrosion and Lightweight

There are certain parts of the country where a corrosion resistant roof is highly desirable. Any area that is coastal or near a body of salt water can benefit from aluminum. Aluminum does not rust. However, it does form oxidation. In fact, the reactivity of the metal itself is what helps to keep it impenetrable to corrosion. As the aluminum is exposed to air, it almost immediately oxidizes to create an aluminum oxide layer. This keeps the aluminum metal underneath from further degrading. Aluminum oxide forms whenever the metal is scratched or marred in some way. This means that it protects itself, even if it becomes damaged. 

If you live in an area that is far from either coast, then you may not be as concerned about corrosion. If winter weather and snow are your main concerns, then you should know that aluminum is extremely lightweight. This means that snow on top of the roof will not cause a weight issue where the roof may then collapse. The roof will need a base though since the aluminum is so thin. However, most metal roofs require a base so the roof can retain strength and durability.

Con - The Roof Can Lift And Develop Dents

The lightweight nature of the aluminum can make it quite advantageous in snowy areas. However, this can also cause issues if high winds are something that you experience. Specifically, the low weight can make it so that winds push their way underneath the aluminum and allow the material to lift away from the roof deck.

Not only is aluminum lightweight and formed in thin layers to construct roofs, but the material is soft too. These properties allow for dents from branches, hail, and flying debris. If you live in an area that sees occasional hail storms or high wind storms, then steel may be a better choice for you.

While dents and dings may develop in your roof, these spots will still retain their resistance to corrosion. The damage is often cosmetic, so you do not have to worry about the reduced function of your roof. Check with companies like National Roofing Of Collier Inc  for more information.
