How do I calculate the weight of snow on a roof?
To calculate the weight of snow on a roof, use the first two sections of our snow load calculator. You need to supply the following information: Length and width of your roof. You can enter these values in any units you'd like, including meters and feet. If your roof is pitched, enter the length and width of the flat area covered by the roof.

How to calculate snow load for a pitched roof?
The calculation of the snow load for a pitched roof is a bit more complex than for a flat roof, but we only need to follow 6 steps. ⬇️⬇️ 1. Find the snow load shape coefficient $\mu_ {1}$ 2. Exposure coefficient $C_ {e}$ 3. Thermal coefficient $C_ {t}$ 4. The characteristic snow load value on the ground $s_k$ 5.

Can snow be applied vertically to a pitched roof?
This load is now applied vertically to the pitched roof. Compared to the dead load the snow load is not following the slope of the rafter. But because the roof is pitched, there are 3 different cases that we need to consider due to drifted load arrangements (EN 1991-1-3 5.3.3 (3) + (4)).

How to calculate snow load?
You can also find the load per square meter or square foot of roofing by opening the advanced mode. If you want to calculate these values by hand, use the following formulas: The result - snow load, or the pressure exerted by the snow - has the units of kN/m² or lbs/ft². The weight of snow is measured in kg or lbs.

How do you calculate line load if a roof is pitched?
But because the roof is pitched, there are 3 different cases that we need to consider due to drifted load arrangements (EN 1991-1-3 5.3.3 (3) + (4)). Transformed in a 2d statical system, we calculate the line load (kN/m) from the area load (kN/m 2) by multiplying the area load with the spacing of the rafters = 0.8m.

How much ice is in a roof?
7.5 to 12.5 cm (3 to 5 in) of compacted snow is equivalent to a load of approximately 2.3 kg (5 lbs) per square foot of the roof. 2.5 cm (1 in) of ice is also equivalent to a load of 2.3 kg (5 lbs) per square foot of the roof. Rather than using the formula above, you can enter the requested information in our snow load calculator tool.

Dec 3, 2020 · Example. If you have 2 feet of settled snow, which has a density of 15.61 pounds per cubic foot, the formula for calculating the snow load is: Snow Load = Snow Density (15.61 lbs/ft³) × Depth of Snow (2 ft) The result is approximately 31.22 pounds per square foot of snow load on the roof. Keep in mind that flat roofs are at higher risk for ...
