For instance, roof replacement in urban areas or regions with a high cost of living, such as coastal cities, tends to be more expensive. For homeowners in areas with extreme climates, metal roofs can be an attractive and resilient option. The cost for a standing seam metal roof are slightly higher at $13,600 to $20,400, due to the more complex design. Metal roofs can also help homeowners save on roof cleaning costs as they are less prone to mold and other buildup than other materials.
