Quick Reference: Weight of Roofing Materials
The following table provides typical weights for various roofing materials. Where possible, the values were taken from manufacturer technical data sheets and are the actual weights of specific, representative products. In a few cases, the weights we give were calculated using manufacturer data, or taken from a non-manufacturer source that we consider reasonably authoritative. In all cases, these values are meant to provide a general idea of what the various roofing materials weigh, and should not be used if precise values are needed for critical engineering calculations. When precision is necessary, always refer to the data sheets of the actual, specific product you intend to use, or contact the technical department of the product manufacturer or material provider.
Note that roof assemblies typically include more than one type of material. A built-up roof, for instance, will also include some kind of insulation and cover board. Don’t forget to include all roof system materials when calculating roof weight.
