Jan 17, 2024 · These calculators consider factors such as roof slope, geographic location, and design parameters to determine the approximate snow load. By inputting specific data, you can easily calculate the estimated snow load your roof needs to bear.
Snow load is the additional weight on a roof structure added by snow and ice buildup on the roof. Calculating the snow load is crucial to determining if the structure can handle the snow’s additional weight.

The roof’s dimensions are important when calculating the weight of the snow it supports. The larger these variables are, the greater the snow load will be. In the formula used to determine the weight of snow on a roof, the length and width of the roof (expressed in feet or metres) are multiplied together to obtain the surface (or area) that is cove...
The roof pitchalso has an important role to play in calculating the weight of snow on a roof. As a general rule, the steeper the pitch, the lower the snow load will be. In the formula, a slope expressed in degrees of inclination should be used.
Snow load is generally measured in lb/ft² or kg/m². It is the last variable you need to apply the formula. It can be obtained by multiplying the snow depth by the snow density. However, since it can be difficult to know the exact density of each layer of precipitation on a snow-covered roof, here are some examples of snow loads based on the quality...
Dec 3, 2020 · If you have 2 feet of settled snow, which has a density of 15.61 pounds per cubic foot, the formula for calculating the snow load is: Snow Load = Snow Density (15.61 lbs/ft³) × Depth of Snow (2 ft) The result is approximately 31.22 pounds per square foot of snow load on the roof. Keep in mind that flat roofs are at higher risk for snow load ...
Mar 16, 2024 · Snow can vary in weight from a little over a pound to as much as 30 pounds per cubic foot. Fresh, dry, fluffy snow might only weigh about four pounds per cubic foot. Snow that has been sitting for a few days under normal conditions will usually weigh around 15 pounds per cubic foot.
