Snow Load Calculator
Calculate the weight of snow on your roof or structure to assess safety and plan snow removal
Snow Load Calculator
Calculate the weight of snow on your roof or structure.
What is Snow Load?
Snow load refers to the weight of accumulated snow on a roof or structure. Excessive snow load can cause structural damage, roof collapse, or safety hazards.
The Formulas
Our calculator uses industry-standard formulas:
Snow Load = Thickness × Density
The result is snow load in kN/m² or lbs/ft² (pressure exerted by snow).
Snow Weight = Length × Width / cos(pitch°) × Snow Load
The total weight of snow on your roof in kg or lbs, accounting for roof pitch.
Why Use This Calculator?
- Safety First: Determine if your roof can safely support the current snow accumulation.
- Prevention: Plan for snow removal before dangerous loads build up.
- Insurance: Document calculations for insurance claims if damage occurs.
- Building Codes: Compare against local building code requirements.
When to Use It
Use this calculator during or after snowstorms, especially in areas with heavy snowfall. Check regularly during winter months and before major storms.
