What are the advantages and disadvantages of using aluminum sheets for roofing?

Aluminum sheets for roofing offer several advantages, including durability, resistance to rust and corrosion, lightweight nature, and energy efficiency due to reflective properties. They are also easy to install and maintain, and can be recycled, making them environmentally friendly. However, there are some disadvantages such as being more expensive than some other roofing materials, potential for denting if not properly installed, and noise issues during heavy rain or hail due to their lightweight nature. Additionally, they may require more frequent replacement compared to some other materials.
