Weight of ice and snow on roof.
Our snow load calculator helps you to make the decision when to remove the snow from your roof by comparing the weight of snow with the load carrying capacity of the roof.
And when snow inevitably melts it can cause major flooding and problems with home septic systems.
Homes in areas prone to heavy snowfall require special engineering to support the load.
Roof collapse can happen when a roof can t bear the weight of ice and snow.
However there are conditions and limitations.
Since snow falls at slow steady speeds large quantities of snow can fall on the roof resulting in bowing.
It is also important to remember that that math doesn t take into account any ice you have on your roof which weighs much more than heavy wet snow weighs.
On average two feet of snow can equal up to 19 tons of weight on your roof which can significantly weaken the structure.
This down bearing pressure can cause the roof to bow and result in ponding under the roof structure.
Insurance may help cover the cost of replacing or repairing a roof that is damaged or destroyed by a collapse.
It is not advisable for a person to climb onto a snow or ice covered roof to remove accumulations.
As snow falls it can accumulate on your flat roof putting unnecessary weight on the structure.
While snow which is a crystalline form of ice is lighter in weight than solid ice each cubic foot of snow adds 17 pounds per square inch to the roof.
The weight of ice and snow on a roof has the potential to cause winter disasters.
