❄️ Roof Snow Load Calculator
Whether you’re battling Nor’easter blizzards or lake-effect snow squalls, our tool helps prevent roof collapse by calculating psf (pounds per square foot) snow loads. While sunny California roofs rarely need shoveling, Alaskan-record snowfalls (like the 1963 78″ accumulation) remind us why proper snow load management matters.
❄️ Snow Weight: 0 lbs (0 psf)
🏠 Roof Capacity: 0 psf
STATUS: INPUT REQUIRED
⚠️ Important: This calculator estimates dry snow equivalent weight and doesn’t account for:
- 🔺 Roof slope factors
- 💧 Ice dam formation
- ⚖️ Local building codes (check IRC 2018 Chapter 8)
