Metal roofs can rust, but steel is a material that holds up well to environmental factors, especially if it’s painted or galvanized. One of the main determining factors regarding rust is the environment the roof is in. Harsher environments with a lot of salt in the air will rust much more quickly than a steel or metal roof in a dry climate. Zinc-coated steel, called galvanized steel, is excellent at preventing rust from forming.

A metal roof can significantly reduce your energy bills by reflecting heat away from your home, so your cooling system doesn’t need to work as hard to keep the inside cool. After installing a metal roof, you may see up to 40% lower energy costs, depending on how energy efficient your previous roof was and your area’s average climate.

Metal roofing gets hot when it’s exposed to direct sunlight, but aluminum is naturally reflective and can actually help keep your home cooler in hotter, sunnier climates. The solar reflectance of aluminum is significantly higher than that of asphalt shingles and clay tile, so a metal roof will reduce solar heat gain in your home.
