Is metal roofing heavier than shingles?

Metal roofing, on average, can weigh up to 3 pounds per square foot. The weight on your roof will depend on the style you choose, the gauge of the metal,  and the panel's profile.  Metal roofing is light compared  with other systems. For example, asphalt shingles can weigh up 3.5 pounds per square foot, and clay or concrete tiles up to 10 pounds per square foot.
