How To Measure Weight Of Snow On Roof

As snow falls it can accumulate on your flat roof putting unnecessary weight on the structure.

How to measure weight of snow on roof.

Since snow falls at slow steady speeds large quantities of snow can fall on the roof resulting in bowing. There is a calculation for this too. Calculating snow load on your roof depends on two factors. With this information you re now likely wondering about the weight of snow load on your roof.

However if the weight of snow will be predetermined as well as the loading capacity of the roof collapse can be prevented. To figure out the load on your roof take the depth of snow in feet and multiply it by the weight of a cubic foot of snow. For example 4 kg per cubic metre x 0 38 m 1 52 so the. 1 25 times 9 comes to 11 25 so the amount of pressure the snow is exerting on the ground is 11 25 pounds per square foot multiply the area of the roof in square feet by the snow load.

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. To find volume measure the length. Unsurprisingly wet snow is the heavy stuff. 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.

Calculate the snow volume. On average two feet of snow can equal up to 19 tons of weight on your roof which can significantly weaken the structure. 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. Calculating snow load on roof.

This down bearing pressure can cause the roof to bow and result in ponding under the roof structure. 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. This quantity of snow may weigh up to 91 kg 20 lb depending on how fluffy or dense it is. If it snows 5 of wet snow it will weigh about 12 5 pounds.

Rain sleet and ice add to the weight of existing snow. If your roof is 1 000 square feet the total snow load is 15 000 pounds of snow. If the snow weighs 10 pounds per cubic foot and there are 1 5 feet on the roof each square foot of the roof is getting 15 pounds of pressure. Multiply the depth of snow by the weight.

Consider removing accumulated snow from your roof to avoid collapse. Let s say our snow weighed 9 pounds per cubic foot. The volume of snow is a major factor that contributes to the total weight.
