When building a new home or renovating an existing one, roofing is a subject that may arise. There are various materials that can be used including metal. The cost of metal roofing will vary depending upon what kind of metal you choose and where you buy it from. On average, you can expect to pay anywhere from $100 to $600 per square. A square is not a tile, but rather a bundle of tiles together equaling one hundred square feet. In the realm of square feet, you can expect your metal roofing materials to cost you between $2 and $6 per square foot. These calculations can help you develop the budget for your roofing project.
