The average lifespan of a metal roof, such as galvanized steel, typically ranges from 40 ke 70 bertahun-tahun. 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, dan tingkat pemeliharaan. Proper installation and regular care, such as cleaning and addressing damage promptly, are crucial for extending the roof’s life. Selain itu, 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.
