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. 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.

In a few cases, the weight of roofing materials we provide was calculated using more general manufacturer data, or taken from a non-manufacturer source that we consider reasonably authoritative. Where possible, the values for the weight of roofing materials were taken directly from manufacturer technical data sheets and are the actual weights of specific, representative products. These values can be considered the dead load values or self-weight of roofing materials. The following table provides typical values for the weight of roofing materials and related building products. Both the weight of roofing materials and the square footage they cover are typically given in the product description, which allows you to figure out the weight per square foot of actual roofing products.

You can also look at roofing materials on the Home Depot website. The staff in the technical department can usually answer any other question you might have, too, and they always seem happy to talk to someone!įor links to a huge directory of roofing manufacturers, organized by roofing material and product type, see our Roofing Manufacturers Directory.

When it comes to estimating the weight of roofing materials for an existing roof, field verification of the in-place construction is necessary in order to see what materials are actually present on the roof. Roof systems typically include more than one type of material, and the weight of a roof system can be determined by adding up the weights of the different roofing materials used in that system.Ī built-up roof, for example, will typically include the built-up membrane itself, the layer of gravel for a gravel-surfaced roof, and the insulation and cover board, which will vary in thickness and material type from roof to roof. Roof systems can vary wildly by weight, from well under a pound per square foot for an aluminum standing seam metal roof to over 15 pounds per square foot for very thick clay roof tiles. The total weight of a roof depends on the type of roof system (and the size of the roof, of course).
