The average lifespan of a metal roof, such as galvanized steel, typically ranges from 40 to 70 years. This longevity is attributed to the material’s durability and resistance to various weather conditions. Factors influencing its lifespan include the thickness of the zinc coating, the method of galvanization, environmental exposure, and the level of maintenance. Proper installation and regular care, such as cleaning and addressing damage promptly, are crucial for extending the roof’s life. Additionally, painting or coating can offer extra protection. While metal roofs may have a higher initial cost, their long lifespan and low maintenance can provide significant savings over time.
