Is it too heavy for some home & structures?


No!


Metal roofing systems generally weigh half of what other materials weigh.  Less than 3 pounds per square foot.  *The actual weight is dependent upon metal gauge and profile of the panel.  


Surprisingly, the weight of a metal roof is significantly lighter than any other type of roofing materials. It typically weighs less than one-third of the weight of an asphalt or  fibreglass shingle roof and is much lighter than clay, concrete, or slate at about 75%.


This makes metal roofing a great choice for just about any application!
