F or homeowners, deciding the roofing material is vital. If you plan to install a new roof, a metal roof is a better option in terms of longevity, maintenance, and energy efficiency. However, a common question arises in mind. How long do metal roofs last? Well, the lifespan depends on the variety of factors and types of material used. For example, standing seam metal roofs have a life between 50-70 years, whereas screw-down metal roofs last between 20-30 years.
The lifespan can’t be predicted accurately because many factors affect durability, such as weather conditions, ventilation, maintenance, and many more. Metal roofing is becoming a popular choice for residential roofing. Though it’s expensive compared to other materials, the longevity balances the cost in the future.
