Q: How much do metal roofs cost? A: As with most roofing options, installation is a large percentage of the total cost, and this varies widely depending on your specific geographic area and the complexity of your roof. Depending on the metal roof purchased, the total installed cost could vary from $125 to $1100 per square. A square is equal to 100 square feet and is the measurement that is used to determine the size of your roof coverage area for quoting. Since metal is a premium upgrade, you can expect to pay more up-front than you would for a quality asphalt shingle. However, over the life of the roof, metal can save you over 60% in total installation and maintenance costs. To make an informed decision, make sure your dealer or contractor quotes the full range of paint grades and gauges available. Stepping up to a premium grade typically adds very little to the overall cost since installation is such a large component. In many cases, a few hundred dollars can mean the difference between getting an unwarranted low-end grade or a premium grade with a Lifetime transferable warranty.
