How to Calculate the Snow Load for Your Roof
To figure out the snow load on your roof, you need to consider both the depth and the density of the snow after it falls. Try this method after an “average” yearly snowfall or after a particularly bad storm.
Use a yardstick or measuring tape to measure the depth of snow in several spots on your roof.
Avoid measuring near edges or uneven areas. Aim for flat sections to get an accurate average.
Calculate the average snow depth by measuring in multiple spots and dividing the total by the number of measurements.
Measuring in several different areas is important because wind and roof pitch can cause uneven snow accumulation.
If you don’t feel comfortable getting up on the roof (or close to it), you can also try a slightly different method. Push the snow back a few inches from the roof edge with a broom or rake, then measure the exposed depth from the side. It isn’t quite as accurate, but it will still work.
Estimating Snow Density on Your Roof
Snow varies widely in weight depending on whether it’s fresh and fluffy or wet and compact. See the chart below for a quick breakdown of the standard densities for different snow types. It’s measured in pounds per cubic foot to keep it simple.
Type of Snow Snow Density (lbs/ft³)
Fresh snow 3.75
Damp fresh snow 6.87
Settled snow 15.61
Wind-packed snow 23.41
Very wet snow 46.82
Ice 57.25
Using These Measurements to Estimate Snow Load on Flat Roofs
To estimate the snow load on a flat roof, use this online calculator or the formula below:
Snow Load = Snow Density (lbs/ft³) × Depth of Snow (ft)
Example:
2 feet of settled snow has a density of 15.61 pounds per cubic foot.
The formula would be: 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 issues since the snow doesn’t slide off easily.
