25YR Coastal Metal Roofing by Premier Metal Roof Mfg.
GET COASTAL BEAUTY WITHOUT THE RUST.
welcome to the x factor
GalvaMAX™ and CoastalMAX™ were built for those who build the coast — the developers redefining skylines and the architects shaping Florida’s most iconic homes and communities. You no longer have to choose between form and function.

These standing seam metal roof systems deliver the clean lines you crave, the strength codes demand, and the salt-air resistance coastal life requires — all backed by 25 years of proven performance up to the water’s edge along Florida’s Gulf Coast and any site 300 feet or more from breaking surf.
Born On The Highway
Perfected for the Coast.
Salt. Snow. Endless splash from salted northern highways was eating away at guardrails built to protect lives. Aluminum was too weak. Steel was strong, but too corrosive. A better solution was needed.

The answer: Zinc-Aluminum-Magnesium alloy—engineered to be strong, salt-resistant, and proven in the harshest conditions. What kept highways safe mile after mile is now protecting rooftops with GalvaMAX™ and CoastalMAX™.

This breakthrough delivers 25-year marine-grade performance across Florida’s toughest coastlines and waterways—standing up to Gulf storms, salt air, and everything in between.

When protection matters most, choose what’s already proven—mile after mile, storm after storm.
Available in high-strength 24ga steel
