Palm Beach is a paradise of swaying palms, stunning ocean views, and endless sunshine. But behind the beauty lies a hidden danger for homeowners: salt air. Over time, that crisp ocean breeze can do serious damage to roofs, leading to unexpected repairs and costly replacements.
If you live anywhere near the coast, understanding how salt air impacts your roofing—and why metal is the superior choice—is critical to protecting your investment. Let’s dive into the real effects of coastal living on roofing materials, and why so many Palm Beach homeowners trust Ametco Metal Roofing, Inc. to shield their homes.
The Unseen Enemy: How Salt Air Wears Down Your Roof
It’s easy to think of salt air as harmless—after all, it’s invisible. But this constant, salty mist carries microscopic salt particles that settle on exposed surfaces, including roofs. Over time, these particles act like tiny corrosive agents, slowly breaking down materials and finishes.
The process is especially aggressive in Florida’s humid environment, where moisture gives salt particles the perfect conditions to stick and react. Even when the sun is shining, corrosion is happening at a microscopic level, eating away at roofing materials day after day.
Here’s how salt air impacts common roofing materials:
Common Roofing Materials vs. Salt Air: A Tough Battle
1. Asphalt Shingles
Asphalt shingles dominate many inland communities, but they’re no match for the coastal environment. The salt-laden moisture seeps into the tiny cracks and edges of the shingles, accelerating deterioration. Over time, shingles can blister, crack, or even slide off entirely during high winds, leading to frequent maintenance headaches.
2. Wood Shakes
Wood roofing may look charming, but it struggles terribly in salt-heavy air. Salt encourages wood to retain moisture, making it a breeding ground for mold, mildew, and rot. Even treated wood shakes often fail prematurely near the coast, requiring replacement far sooner than expected.
3. Clay and Concrete Tiles
Clay and concrete tiles fare better in coastal climates, but they’re not invincible. Salt can seep into small pores and hairline cracks, leading to gradual erosion or spalling (surface flaking). The salty environment also weakens the mortar used to secure tiles, risking dislodgment during storms.
Why Metal Roofing Excels Against Salt Air in Palm Beach
Now, here’s where metal roofing shines—literally and figuratively. When properly selected and installed, metal roofing offers unmatched resistance to the salt air that wreaks havoc on other materials. Here’s why metal wins the coastal battle:
1. Natural Resistance to Corrosion
Certain metals—like aluminum, zinc, and copper—have natural corrosion resistance that makes them ideal for coastal environments. Aluminum, in particular, doesn’t rust at all. Even steel can be fortified with protective coatings like Galvalume, providing a reliable barrier against salt damage.
2. Minimal Moisture Absorption
Unlike wood, asphalt, or tile, metal doesn’t absorb moisture. That means there’s little opportunity for salt to cling and corrode the surface, especially when maintained properly. With regular inspections and occasional cleaning, a metal roof can withstand decades of coastal exposure.
3. Superior Durability During Storms
Palm Beach residents know that hurricanes and tropical storms are part of life. Metal roofs are engineered to handle extreme wind speeds, often exceeding local building codes. When secured with standing seam systems and hurricane-rated fasteners, metal roofs stay firmly in place even when the storms rage.
4. Reflectivity and Energy Efficiency
Beyond its strength, metal also reflects solar radiation, which reduces attic temperatures and lowers energy bills—a huge advantage in the Florida heat. Choosing ENERGY STAR-rated reflective coatings enhances this effect even further, helping homeowners save money year-round.
The Best Metal Roofing Materials for Palm Beach Homes
Choosing the right type of metal makes a big difference when building a coastal-resistant roof. Here’s a closer look at top options:
1. Aluminum Roofing
For homes close to the shoreline, aluminum is a top choice. It’s lightweight, corrosion-proof, and incredibly energy-efficient. Aluminum roofs can also be coated with high-performance finishes that further protect against fading, chalking, and salt exposure.
2. Galvalume Steel Roofing
Galvalume steel combines the strength of steel with a protective coating of aluminum and zinc. This fusion offers strong corrosion resistance, making Galvalume an affordable option for homes that are a few miles inland. It also delivers excellent longevity with minimal maintenance.
3. Copper Roofing
While copper comes with a higher price tag, it offers an unrivaled lifespan—often 70 to 100 years—and a timeless beauty. Copper develops a stunning green patina over time that not only adds elegance but also enhances its natural resistance to salt air.
4. Zinc Roofing
Zinc roofing is less common but offers outstanding durability and self-healing properties. Minor scratches and marks on a zinc roof will “heal” themselves over time, thanks to the natural patina that forms on the surface. It’s an eco-friendly choice for coastal homeowners who want long-term performance.
Installation Matters: Why Professional Craftsmanship Is Key
Even the best metal materials can fail if installed improperly. Coastal metal roofing requires expert techniques to ensure panels are fastened securely and seams are properly sealed against moisture intrusion.
That’s why working with a local specialist like Ametco Metal Roofing, Inc. is critical. They understand the unique conditions in Palm Beach and bring decades of coastal roofing expertise to every project.

Protecting Your Metal Roof from Salt Air: Simple Maintenance Tips
Metal roofs are famously low-maintenance, but a few simple steps can help them last even longer:
- Rinse your roof occasionally. A gentle hose rinse removes salt buildup.
- Schedule annual inspections. Have a roofing professional check for loose fasteners, worn coatings, or other minor issues before they become big problems.
- Touch up protective coatings as needed. If scratches or dings occur, spot-treating them helps maintain full corrosion resistance.
Fortunately, with quality materials and expert installation, maintenance is minimal—and well worth the effort to protect your investment.
Conclusion:
Salt air is an inevitable part of life in Palm Beach, but roofing headaches don’t have to be. Traditional materials like asphalt, wood, and even tile struggle under coastal conditions, while metal roofing rises to the challenge.
With its superior corrosion resistance, energy efficiency, and storm durability, metal is hands-down the best roofing option for coastal homes.
