Metal roofing is one of the most reliable roof systems that you can use for your home. It’s best known for its strength and resiliency, longevity and minimal upkeep. However, like in all other roof types, poor or incorrect installation can cause problems sooner than you would expect.
In this article, trusted roof repair expert State Roofing discusses how galvanic corrosion occurs. We also briefly explain how it can affect your metal roof.
What Is Galvanic Corrosion?
Galvanic corrosion happens when one metal corrodes after being in contact with another metal and a certain type of electrolyte such as water. It often results in rust stains, which could affect a small area or the entire roof surface. Over time, the damaged panel can deteriorate and potentially affect your entire roof system.
What Causes Galvanic Corrosion?
Lead and copper are the usual culprits when it comes to galvanic corrosion so make sure these metals don’t mix. Double-check the metals that are going to be used in installing your roofing. Pay close attention to the panels and fasteners.
If you’re unsure of the metal compositions of the materials you’re considering, ask an expert for help. Proper metal combinations can help you ensure a durable metal roof. Additionally, you might want to coat the steel panels of your metal roof with a zinc or aluminum coating. This type of coating protects the steel parts from unsightly corrosion.
