The answer to 'lifespan of metal roof' is that a properly installed and maintained metal roof can last 40-70 years or more. Metal roofs are extremely durable and long-lasting, with a lifespan that is significantly longer than traditional asphalt shingle roofs, which typically last 15-30 years. Metal roofs are resistant to fire, rot, insects, and weather damage, making them a highly reliable and low-maintenance roofing option for homeowners.
The exact lifespan of a metal roof can vary depending on the specific metal alloy used, the quality of the installation, and the local climate and weather conditions. High-quality steel or aluminum metal roofs tend to have the longest lifespans, while cheaper metal roofing materials may have a shorter lifespan. Proper maintenance, such as regularly inspecting and addressing any minor issues, can also help extend the lifespan of a metal roof.
