Make sure to not wait for too long though.
Roof snow load support.
If the weight of the actual snow load exceeds the weight a structure was designed to support the roof or even the entire structure can fail.
The term snow load refers to the downward force on a structure s roof by the weight of accumulated snow and ice.
P s c s p f.
The thermal factor c t from table e 3 determines if a roof is cold or warm slippery surface values shall be used only where the roof s surface is unobstructed and sufficient space is available below.
Basing on the roof parameters you specified in the first section our snow load calculator displays the maximum allowable snow cover thickness and snow weight.
The live load depends on the maximum snow load in your area.
Snow loads acting on a sloping surface shall be assumed to act on the horizontal projection of that surface.
Overall a plan should be established by greenhouse operators before winter weather arrives.
Determine the load per square foot that the roof must support.
The sloped roof snow load p s shall be obtained by multiplying the flat roof snow load p f by the roof slope factor c s.
If your roof is 1 000 square feet the total snow load is 15 000 pounds of snow.
The dead load is constant and is estimated as 10 pounds per square foot for wood framed construction.
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.
It also informs you whether you should immediately remove some of the snow or you can wait a little bit longer.
