There are many advantages to getting a coastal metal roof. Florida’s coastal communities bear the brunt of our hurricane seasons, but metal roofs will stay in place and protect your property even through a major hurricane. That said, there are unique concerns for a metal roof near Florida’s coastline.
That’s why we’re here. As your local roofing partner, PITCH Roofing has all the information you need on how to plan the best metal roofing experience for coastal areas. Today we’re talking about planning a metal roof replacement as well as maintaining a metal roof near the coasts. Keep reading for crucial information on coastal metal roofs!
Unique Concerns for Coastal Metal Roofs
Before we discuss how to plan and take care of your coastal metal roof, we first have to talk about what it’s up against. Life on Florida’s coasts can be beautiful, but it’s tough on roofs. For one thing, hurricane-force winds are a major concern in the summer. This means your metal roof has to be able to withstand winds in excess of 140 mph.
The humidity and saltwater air can be just as damaging as the hurricane-force winds, though. Salt air can cause corrosion, even on metal roofs that could normally withstand Florida’s humidity. This is why coastal metal roofs require specialized, anti-corrosive roofing materials.
Whether you’re in Pinellas or Palm Beach Counties, your coastal metal roof will need to withstand occasional hailstorms and storm debris. Some softer metals can be prone to denting, which can cause aesthetic issues on your metal roof. Thankfully, though, it’s rare for hail or storm debris to cause meaningful damage to a metal roof in Florida.
All together, the performance requirements of a metal roof on Florida’s coasts are extremely high. Thankfully, there are metal roofing materials that are up for the job. Let’s talk about your best bet for a Florida-proof metal roof on the coasts.
Coastal Metal Roofing: Aluminum vs. Galvalume
| Feature | Aluminum (Coastal Best) | Galvalume Steel (Standard) |
|---|---|---|
| Saltwater Resistance | 100% Immune (Naturally Non-Corrosive) | Moderate (Coating eventually fails) |
| Ideal Location | < 1 Mile from Coast | Inland Florida |
| Wind Rating | Hurricane Rated (140+ MPH) | Hurricane Rated (140+ MPH) |
| Durability | High (But softer, prone to dings) | Very High (Harder, resists dents) |
| Energy Efficiency | Excellent (High UV Reflectivity) | Good (Reflects Heat) |
The Best Metal Roofing Material for Coastal Areas
In Florida, Galvalume steel is among the top-rated metal roofing materials. It’s strong, durable, and it has an anti-rust coating that prevents corrosion. However, it just can’t stand up to the high demands of Florida’s coasts. So what’s the go-to roofing material for metal roofs within a mile of the coastline? Aluminum is the best roofing material for coastal metal roofs. While it’s extremely lightweight, it doesn’t sacrifice strength or durability, meaning it will protect against hurricane-force winds. And aluminum is unique among metal roofing materials because it is naturally immune to rust. This makes it a perfect fit for the coastline, where saltwater air will eat through anti-rust coatings much faster than you’d expect. Another key benefit of aluminum metal roofing is its UV reflectivity. By directing UV rays away from your home, an aluminum roof prevents premature degradation of your roofing materials. At the same time, this also lowers your energy bills by reducing how hard your HVAC system needs to work in the hot Florida summers. There is one notable downside to aluminum: its softness. While it’s a strong roofing material, aluminum is not as hard as steel. This means it’s possible for hail or storm debris to dent your metal roof. While this isn’t ideal, it also isn’t likely to do significant damage to your roof — more realistically, you may be looking at a few dings over the years. This isn’t ideal, but for our money, it’s not enough to override the many benefits of metal roofing near Florida’s coasts. Protecting your roof from Florida’s coastal weather patterns requires more than just picking the right material, though. Coastal metal roofs have special roof maintenance requirements that you’ll need to follow to maximize your roof’s lifespan.The “One Mile” Benchmark
If your home is located within one mile of the coastline, standard Galvalume steel isn’t enough. The salt air will eventually eat through the protective coating. For these properties, we almost exclusively recommend Aluminum roofing because it is naturally immune to rust.
Maintaining a Metal Roof on the Coasts
Taking care of a coastal metal roof does require some extra work, but the demands thankfully aren’t too bad. Perhaps the most important piece of metal roof maintenance is preventing salt buildup on your roof. To minimize corrosion, it’s a good idea to rinse your coastal metal roof with freshwater from a hose at least a few times per year. This way, salt won’t have the opportunity to build up on your roof and start chipping away at your roof’s protection.
It’s also a good idea to take a look at what’s around your roof. Overhanging tree limbs can pose a risk to your metal roof, especially during hurricane season when high winds can knock branches loose. When these fall on your roof, they have the potential to dent your roof, or worse, scratch away your protective coatings. By trimming any overhanging branches about twice a year, you can minimize this risk and keep your roof safe.
Finally, the most important piece of coastal metal roof maintenance is keeping up on your roof inspections. Roof inspections lower your overall roofing costs by helping you identify when they’re small and easy to fix. If you wait until your roof is leaking to have contractors look at your roof, the repair bill will be much higher than having them catch the problem early. At PITCH, we recommend annual professional roof inspections, as well as taking a quick look at your own roof after major storms.
Metal roof maintenance is extra responsibility, but following it is essential to getting the best performance from your roofing system. By taking these necessary steps, you can protect your roof and your property from the worst that Florida’s coastal climate can dish out. The “Freshwater Rinse” Rule
Living near the ocean? Salt buildup is the enemy of any roof. We recommend grabbing a garden hose and giving your coastal metal roof a gentle freshwater rinse a few times a year. This simple step prevents corrosion and extends the life of your finish significantly.
Coastal Metal Roof Replacement FAQs
Aluminum is the best material for coastal metal roof replacement. Unlike steel, aluminum is naturally immune to rust, making it the only metal roofing option that can withstand the relentless saltwater air found within a mile of the Florida coastline.
It can, if you choose the wrong material. Standard steel roofs rely on a zinc/aluminum coating (Galvalume) to stop rust. Over time, salt air eats through this coating, causing the steel core to rust. This is why we recommend rust-proof aluminum panels for coastal properties.
While aluminum is softer than steel and can be prone to cosmetic dings from heavy storm debris, it is structurally incredibly strong. It is rated to withstand hurricane-force winds in excess of 140 MPH, ensuring your home stays protected even if the roof takes a few aesthetic dents.
Maintenance is simple but vital. We recommend rinsing your roof with fresh water 2-3 times a year to wash away salt accumulation. Additionally, keep overhanging tree branches trimmed back to prevent them from scratching the protective paint finish during high winds.
