There are a number of styles and materials that are available when installing a metal roof. To begin, there are a few different types of metal to choose from, including steel, aluminum, copper, tin, and zinc. Then comes the panel profile of the roofing system. You have two options here: exposed fastener panels or concealed fastener panels. The concealed system will typically cost you twice as much as the exposed fasteners would. You also have different options when it comes to the gauge or thickness of the metal, usually ranging from 29 gauge to 20 gauge. A galvalume base is typical for metal roofs, with a paint finish applied on top. The variety of colors and designs that are available with metal roofing is another one of its distinguishing features. You can almost always find whatever color you want, and designs range from corrugated metal to tile, slate, and more! You can even install a metal roof that mimics the appearance of traditional shingled roofing.
