A metal roof is a roofing system composed of metal panels or shingles, typically made from steel, aluminum, or copper. Known for durability and longevity, metal roofs provide excellent resistance to weather elements, including rain, snow, and UV rays. They are energy-efficient, reflecting sunlight to reduce cooling costs, and come in various styles and finishes, offering versatility in design. Metal roofs are a popular choice for both residential and commercial buildings.
