Heavy snow accumulation on your roof can pose a serious structural risk. This Snow Load Weight Calculator helps you estimate the weight of snow on your roof based on the area, snow depth, and snow density. With this tool, you can quickly determine whether your roof might need snow removal before damage occurs.

Formula for Snow Load (psf)

$\text{Snow Load (psf)} = \frac{\text{Snow Depth (in)} \times \text{Snow Density (lb/ft³)}}{12}$

Formula for Total Snow Weight (lb)

$\text{Total Snow Weight (lb)} = \text{Snow Load (psf)} \times \text{Roof Area (ft²)}$

Formula for Metric Units (kPa)

If using metric units:

$\text{Snow Load (kPa)} = \frac{\text{Snow Depth (cm)} \times \text{Snow Density (kg/m³)} \times 9.81}{1000}$

Example Calculation

Given:

Roof Area = 1,000 ft²
Snow Depth = 12 inches
Snow Density = 20 lb/ft³

Step 1 – Calculate Snow Load:

$\text{Snow Load} = \frac{12 \times 20}{12} = 20 \ \text{psf}$

Step 2 – Calculate Total Snow Weight:

$\text{Total Snow Weight} = 20 \times 1000 = 20{,}000 \ \text{lb}$
