In hot and humid areas, the paint may last 8-10 years. In milder climates, it can last 15-20 years. Roof type and pitch also impact durability. Steeper, smoother metals like steel can maximize paint adhesion and lifespan.
How Often Should You Coat A Metal Roof? You should typically recoat a metal roof every 10 to 20 years for optimal protection and longevity. Is It Cheaper To Paint Or Replace A Metal Roof?
