Calculate the snow load on the roof and assess the structure’s durability.
The snow load calculator calculates the roof snow load in kg or kN based on the thickness of the snow layer and the roof area. Snow is heavy – 0.39 in of wet snow weighs about 10 kg/m².
The calculator is free, works in the browser, and does not require registration. This site offers over 200 calculators with 2026 data.
Load (kg) = Snow Thickness (m) × Snow Density (kg/m³) × Roof Area (m²). Dry snow ~100 kg/m³, wet snow ~300–500 kg/m³.
Fill in your information in the fields and press the calculate button – the result will appear immediately.
Roof 80 m², snow layer 40 cm, wet snow 300 kg/m³ → 0.4 × 300 × 80 = 9,600 kg = 9.6 tons.
