Our metal roofs provide long-lasting energy savings, beauty and protection for your home, garage or carport. They’re made of GALVALUME®, 50% Aluminum-Zinc alloy coated steel. By choosing a metal roof, you'll not only save money, you’ll do your part for the environment. Conventional roofing products like asphalt shingles contribute billions of pounds of waste to U.S. landfills annually. Metal roofs, by contrast, can often be installed over your existing roof, eliminating the cost and ecological impact of tear-off and disposal.
