In areas of the state outside of certified local government jurisdictions the design snow load shall be based on the ground snow loads developed in snow loads for structural design in montana authored by f f.
Nc roof snow and dead loads.
Roof loads are a downward vertical force on the home.
If your roof is 1 000 square feet the total snow load is 15 000 pounds of snow.
The north zone middle zone and the south zone are identified on the roof load zone.
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.

Snow loads are influenced by elevation general weather and moisture patterns slope direction exposure roof or trail bridge configuration and wind direction and severity.
Overestimation of snow loads can unnecessarily increase the cost of construction.
Such requirements must be based on a roof snow load of 0 6 of the ground snow load for areas exposed to wind and a roof snow load of 0 8 of the ground.
The live load on a roof is the weight of any temporary objects on the roof.
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.
The values for dead loads in table 3 2 are for commonly used materials and constructions in light frame residential buildings.
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.

However a south roof load zone home cannot be installed in either a middle or north roof load zone.

The net uplift roof load must not be reduced by the dead load of the roof structure for the purposes of engineering design or structural load testing.
The minimum design roof snow load.
A clay tiled roof may have a dead load of as much as 27 psf.
