The answer to 'what is metal roof' is a type of roofing material made from metal sheets or tiles. Metal roofs are known for their durability, longevity, and resistance to weathering, fire, and pests. They come in a variety of styles, including standing seam, corrugated, and metal shingles, and can be made from materials like steel, aluminum, or copper.
Metal roofs are a popular choice for both residential and commercial buildings due to their low maintenance requirements, energy efficiency, and ability to withstand harsh weather conditions. They are often more expensive upfront than traditional asphalt shingles, but their long lifespan and low maintenance costs can make them a cost-effective option in the long run.
