Metal roofing is considered one of the best options by many professionals for its low maintenance and durability. These are advantages if the roof is properly installed and maintained. Metal roofing comes in many colors and styles and is lightweight. High-end products like Decra (steel metal panels) are beautiful and durable. Metal roofing is also designed in traditional roof styles such as clay tiles, shingles, and shakes with the added advantage of a steel substrate.
