Most metal roofing products consist of steel or aluminum, although some consist of copper and other metals. Steel is invariably galvanized by the application of a zinc or zinc/aluminum coating, which greatly reduces the rate of corrosion.
Metal roofing is available as traditional seam and batten, tiles, shingles, and shakes. Products also come in a variety of styles and colors.
Metal roofs with solid sheathing control noise from rain, hail, and bad weather just as well as any other roofing material. Metal roofing can also help eliminate ice damming at the eves. And in wildfire-prone areas, metal roofing helps protect buildings from fire should burning embers land on the roof. Metal roofing costs more than asphalt, but it typically lasts 2 to 3 times longer than asphalt or wood shingles.
