Metal roofing is a premium product. As such, the initial cost of materials and installation is generally more expensive than other roofing systems. For example, metal roofing costs approximately 2-3 times as much as asphalt shingles. However, metal roofs also last significantly longer than asphalt shingles roofs do. Since metal roofs are maintenance free (and come with warranty coverage) as well as highly energy-efficient, you can expect long-term savings with your investment.
