Can aluminum sheets be installed on existing roofs?

Yes, aluminum sheets can be installed on existing roofs. This process typically involves removing the old roofing material and ensuring the roof structure is sound. Aluminum sheets are lightweight, durable, and resistant to corrosion, making them a popular choice for roof installations. They can be installed over a solid substrate, such as plywood or metal decking, and often require a proper underlayment to ensure watertightness. It's important to follow manufacturer guidelines and local building codes when installing aluminum sheets on an existing roof. Professional installation is recommended to ensure the roof's integrity and longevity.
