About the Roof Weight Chart
The following table provides typical weights (dead load, self-weight) for various roofing materials and related building products.
Where possible, the values were taken directly 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 more general 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.
EPDM rubber, metal tiles, asphalt shingles, modified bitumen, asphalt BUR, PVC, copper panels, roofing slates, and cedar shingles.
Weight of Roof Systems
Note that roof systems typically include more than one type of material.
A built-up roof, for example, will typically include the built-up membrane itself, with or without gravel, as well as some kind of insulation and cover board, which will vary in thickness from roof to roof.
When it comes to estimating the weight of an existing roof, field verification of the in-place construction is necessary.
Don’t forget to add all roof assembly materials when calculating total roof weight. Depending on what you are using this information for, this can include the roof deck and the supporting structure (typically roof trusses and/or rafters) as well as the roof system itself.
Check with the Roofing Manufacturer
Manufacturer technical data sheets (with the material weights) are almost always made available on the manufacturer’s website.
For links to a huge selection of roofing manufacturers, organized by roofing material or product type, see Roof Online’s Roofing Manufacturers Directory.
See roofing materials at the Home Depot.* Both the weight and the square footage are typically given in the product description, which allows you to figure out the weight per square foot of actual roofing products. Home Depot will also deliver to your home, by the way.

Note: These are installed weights. Shingles, tiles, and panels overlap; the weights for these materials will be higher per square foot than for the uninstalled weights of the same materials.
