Did you know that some batteries employ salt solutions to assist in electron transfer? It’s true! Any dissolved ionic compound enhances oxidation and allows for electron transfer much more easily than pure water. So what does this have to do with metal roofing? Living next to the ocean, the environment is full of salt, even the air where salt is dispersed through tiny water particles. These tiny droplets of salt water or “salt spray” are carried through the air via wind and fog and collect on nearby surfaces. Salt spray develops salt deposits on these surfaces that corrode over time. When it comes to your metal roof, a STEEL roof would look like this in about 8-12 years.

As you can see, the drip edge of this metal roof has almost rusted completely. This rust is called iron oxide. It is the compound created when the iron in carbon steel oxidizes. It is also the reason a steel roof should never be used near the ocean.
Instead, the answer is a new 0.032 Aluminum “Rust Proof Roof” from The Roof Duck Watertight Roofing Systems! Although aluminum does oxidize under the same conditions, it is a much different process. Aluminum holds up very well to salt water and salt deposits.
The 0.032 or 0.040 Aluminum metal roofing that our team uses comes from the manufacturer coated in a highly durable Kynar 500 Paint system that resists fade (25-year fade warranty) and is roll formed to your roof panel profile. It serves as an added layer of protection!
