Metal is durable, versatile and energy-efficient, making it one of the most popular commercial roofing systems available today. But it is not without a downside. A metal roof, for instance, can be prone to galvanized corrosion. So, you can gain a better understanding about this issue and how to deal with it, we explain more here.
How Does Galvanized Corrosion Occur in Metal Roofing?
Galvanized corrosion refers to an electrochemical process that happens when one metal comes into contact with a different metal. If you’re investing in a new metal roof this season, make sure the system comes with the proper metal combinations. This avoids galvanized corrosion and ensures your metal roof can deliver the reliable, long-lasting performance weather performance you expect.
How Can You Prevent Galvanized Corrosion?
Avoiding galvanized corrosion starts with your choice of metal roofing. You should consider getting steel panels with a zinc-aluminum, or galvalume®, coating. By replacing the galvanizing process in metal roofs, galvalume allows for a better, more effective protective layer that eliminates the potential for corrosion. However, if you still want to go for galvanized metal panels, you’ll want to make sure they don’t come into contact with lead and copper.
Avoid using lead roof jacks for pipe penetrations because they increase the risk for corrosion. Contact between copper and galvanized metal panels will also cause a negative reaction because copper can eat through metal when exposed to condensation. Learning more about galvanic reactions between dissimilar metals goes a long way in ensuring your new roofing remains durable and corrosion-free.
