Calculate your Roof Snow Load Capacity

To calculate the weight of snow on your roof, use the first two sections of our snow load calculator provided by OMNI Calculator.

You need to supply the following information:

  • Length and width of your roof. You can enter these values in any units you'd like, including meters and feet. If your roof is pitched, enter the length and width of the flat area covered by the roof.
  • Roof pitch. You can enter this value either as a ratio x:12 or as an angle, whichever suits you better.
  • Snow cover thickness. Intuitively, this is the number of inches of snow on your roof in the place where the cover is the thickest.
  • Snow type. The density of snow depends on whether it's fresh, wet, wind-packed, or mixed with ice. If you're not sure which type to choose, always settle for the wetter types, as they are denser.

Once you know these values, our snow load calculator automatically finds the total weight of snow on your roof. You can also find the load per square meter or square foot of roofing by opening the advanced mode.
