Metal roof prices vary based, in part, on the metal used. Galvanized steel is the most common and least expensive metal roofing material commonly available. Aluminum roofs are lightweight and more rust resistant, but usually cost more than steel.
Copper roofs are colorful and long lasting, but they are cost prohibitive for most builders. The cost of metal roofs can change over time depending upon the commodity price of metals. Prices can also vary depending upon the style of metal roof to be installed. Steel shingles, for example, are often cheaper than steel panels. Metal shingles designed to look like a ceramic roof can be more expensive than steel panels.
