An aluminum strip is significantly lighter than many other roofing materials. It weighs approximately 1.5 to 2.5 pounds per square foot, depending on the thickness and profile. In contrast, asphalt shingles can weigh between 2.5 to 4.5 pounds per square foot, while concrete tiles can be as heavy as 7 to 10 pounds per square foot. Clay tiles are also heavier, typically ranging from 6 to 8 pounds per square foot. This makes aluminum strips an attractive option for those seeking a lightweight roofing solution.
