Metal is a premium roofing material manufactured from a high-quality coated steel or aluminum coil.
Most of high-end residential metal roofs are made from either hot-dip galvanized (zinc-coated) G-90 steel used for metal shingles, or Galvalume (an even better type of coating comprised of zinc and aluminum alloy to protect steel sheets from oxidation due to exposure to environmental elements such as oxygen, moisture, salt spray environment, etc.) steel for standing seam panels.
Majority of high-end metal roofing systems and profiles are manufactured from one of the following metals: 24 to 26 gauge steel, 32 to 40 mil. aluminum sheets/coil, and 16 to 20 oz. copper. Zinc and stainless steel can also be used for high-end metal roofs. In fact, some architects often specify zinc standing seam panels for luxurious homes and cabins designs/developments.
Cost of Materials:
Metal shingles generally cost $3.50 to $5.50 per sq. ft. (materials only) for steel and/or aluminum shingles, plus trim and flashing details. Most products have an average cost of $3.00 to $4.00 per square foot.
Standing seam metal panels generally cost anywhere from $3.50 to $5.50 per square foot or $350 to $550 per square (100 square feet), but the cost may be significantly higher for smaller orders.
Standing seam panels are generally 12 to 19 inches wide. They are typically made out of painted galvanized steel/G-90 steel, Galvalume steel (offers greater protection from corrosion than galvanized steel), and aluminum. It is also possible to order a standing seam metal roof made of copper or zinc, but these premium metals are extremely expensive and are not a typical material choice for most homeowners.
