Pros and Cons of a Galvalume Roof in Florida

May 10, 2024

Many people still picture metal roofs as noisy things made of tin, but metal roofing technology has come a long way since then. Now, a Galvalume roof is one of the most widely used options for a metal roof replacement. But because most Floridians aren’t familiar with this metal, they don’t realize how much good it can do for their properties.

As your local roofing partner, it’s our job to spread this crucial metal roof replacement information! Keep reading to hear from the PITCH Roofing experts about everything you should know about Galvalume steel and its value as a Florida roofing material. First, we’re getting started by explaining the basics of Galvalume.

Galvalume Roofing 101: New Steel, Old Protection

Galvalume 101: New Steel, Old Protection

Galvalume steel was invented in the 1970s, but its base materials are tried and true. This new roofing technology comes from a mixture of galvanized steel, aluminum, and zinc. And if your goal is to protect your property in Florida, then this mixture could be perfect for your roof.

Galvanized steel is known for its durability and unrelenting protection. Aluminum complements this strength by providing essential rust resistance. This way, your roof will be much slower to corrode, even with Florida’s year-round humidity.

But when damage does start to develop on your roof, you’ll still be protected. That’s thanks to the zinc in a Galvalume roof, which will shed the damaged parts of itself. For this reason, roofers often say that zinc has “self-healing” properties, and this unique protection provides great longevity for metal roofs in Florida.

This means that in theory, Galvalume steel is perfectly suited to Florida. But a Galvalume roof isn’t the solution to everything. To see if this metal roofing material is right for you, you have to look at the pros and cons!

Pros and Cons of a Galvalume Roof in Florida

Pros and Cons of a Galvalume Roof in Florida

There’s no such thing as the perfect roof. Every roof, even metal ones, will have both good and bad qualities. Now, let’s look at the good and the bad of a Galvalume roof so you can make an informed decision!

Pro: Perfectly Suited to Florida’s Weather Patterns

You don’t need to be a roofing expert to know that the weather in Florida is tough on roofs. Between the humidity, intense UV exposure, and hurricane-force winds, any number of weather events could destroy your roof. But for all of these threats, a Galvalume roof is a pretty good answer.

Galvalume steel is generally rated for up to 140 mph in wind resistance. So even with a major hurricane raging outside, you can rest assured that your roof isn’t budging. And when properly installed, a Galvalume roof should create a waterproof barrier around your structure that keeps water out even when it’s being pushed by high winds.

And while UV rays are a year-round roofing concern, Galvalume steel handles them extremely well. By reflecting UV rays away, it reduces the wear and tear that the sun can do to your roof over time. It also lessens the amount of cooling that your AC system needs to do in the summer!

Con: Occasional Oil Canning

Oil canning is a possibility for any standing seam roof, including Galvalume. And while this isn’t a structural concern for your roof, it’s still worth being aware of as a possibility.

Oil canning is a wavy, distorted pattern that can spread across your roof. It doesn’t weaken your roof at all, but many property owners don’t like the way it looks. Thankfully, there is a way to drastically lower your roof’s risk of developing oil canning.

Developing oil canning is not a random event. It happens when inexperienced roofers install metal roofing panels too closely together, causing them to push against each other as they expand with the sun’s heat. And since it’s due to an installation error, you can minimize your risk by choosing experienced professionals for your Galvalume roof replacement.

Pro: Long-lasting Protection

Thanks to all of its durability features, a Galvalume roof will last for a long time. Even with all of Florida’s harmful weather, Galvalume steel still lasts for around 60 years. This is a good lifespan even for a metal roof since other types of metal roofing might only last around 40 years.

While metal roofs are more expensive than some other roofing materials, they’re worth the investment. A Galvalume roof, for example, will last more than twice as long as a standard shingle roof replacement. This more than makes up for the higher up-front costs of roof installation!

Con: Not Suited for Coastal Florida

Remember how we said that a Galvalume roof is resistant to rust? That’s still true, but there are limitations to this protection. Specifically, Galvalume steel may not be the best choice if you live on one of Florida’s coasts.

The root problem with coastal areas is the salt water. The salt works its way into the air, which can greatly speed up how fast a metal roof will develop rust. And while zinc and aluminum both have great rust-resistant qualities, they’re not immune, and these coatings can’t stand up to salt water over years. So if you live within a mile or two of the coast, you may want to choose another roofing material.

Pro: Low-cost Metal Roofing

When talking about affordable metal roofing, it’s important to have clear standards. An architectural shingle roof will always be cheaper than a metal roof. But when looking at how much metal roofing costs, a Galvalume steel roof costs a very reasonable amount.

So how much does it cost, exactly? The price range for a Galvalume steel roof is between $10 and $19 per square foot. While this isn’t a cheap price, it’s very affordable compared to other metal roofing costs. So if you want the protection of a metal roof without the sky-high prices, a Galvalume roof may be the perfect choice.
