The volume of snow is a major factor that contributes to the total weight.

How to measure weight of snow on roof.

This down bearing pressure can cause the roof to bow and result in ponding under the roof structure. Follow along to find out how to calculate its total weight. If it snows 5 of wet snow it will weigh about 12 5 pounds. 4 multiply the depth of snow in feet by the weight from step 3 of a cubic foot of snow.

Let s say our snow weighed 9 pounds per cubic foot. Collect 0 028 cubic metres 1 cubic foot of the snow on the ground choosing a sample that is representative of the overall snow pack and weigh it. If you live in the us our snow load calculator compares the total weight on your roof with the permissible load calculated according to the standards issued by the american society of civil engineers regarding the minimum design loads for buildings and other structures asce7 16. To measure the snow loading capacity of the roof the area of the roof should be determined by multiplying the length and the width of one face of a gable type roof and multiplying the result by the number of faces.

Consider removing accumulated snow from your roof to avoid collapse. With this information you re now likely wondering about the weight of snow load on your roof.

Calculating the weight of snow is useful when you need to know the total weight it adds for example to calculate the weight on a roof.

There is a calculation for this too. However if the weight of snow will be predetermined as well as the loading capacity of the roof collapse can be prevented. Calculate the snow volume. To find volume measure the length.

It is not advisable for a person to climb onto a snow or ice covered roof to remove accumulations. This quantity of snow may weigh up to 91 kg 20 lb depending on how fluffy or dense it is. Calculating snow load on roof.
