How much snow a roof can hold depends on the type of snow roofline and material among other considerations.
Roof snow holds.
That sounds simple enough right.
Snow guards are roof mounted at spaced intervals and in two or more rows near the edge of a roof.
These occur when snow melts off a roof into the gutters.
This can also happen if you have metal gutters as the metal holds cold temperatures well.
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.
In turn the ice dam will prevent the mass of snow from sloughing off the roof all at once in a single avalanche.
How much snow can a roof hold.
Roof snow loads indicate the amount of additional force pressing down on a building when snow and ice pile up on the roof during winter storms.
It calls for 20 psf throughout most of ohio and 25 psf along a north south strip in the eastern half of the state.
These questions aren t quite so easy to answer because there are several variables.
Well there are a lot more variables than just the amount of snow on the roof.
The idea is that as snow and ice back up against the guards it will harden and create a dam.
The residential code of ohio which applies to one and two family homes shows a map indicating the required snow load.
If the gutters are blocked then the melted snow can t run away as it normally would.
If your roof is 1 000 square feet the total snow load is 15 000 pounds of snow.
