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

Advantages of using aluminum sheets for roofing include their lightweight nature, which reduces structural load; corrosion resistance, making them suitable for coastal areas; and low maintenance requirements. They are also energy-efficient, reflecting heat and reducing cooling costs. Disadvantages include the potential for dents and damage from hail or heavy impacts, and they can be more expensive than some other roofing materials. Additionally, aluminum can be noisy during rain, and it may require more frequent replacement compared to some other materials due to its lighter gauge.
