Most snow-related building losses typically occur at stepped elevations where blowing snow is carried from an upper roof down to a lower roof.
- Heavy and repeated snowstorms can create packed snow and ice conditions resulting in unusual and excessive snow loads of 50 p.s.f. or greater.
- Blowing and drifting snow can add to these loads
- Rain-on-snow can cause significant load increases
- These loads can be in excess of the design capacity of the building and can cause damage, collapse, or at worst, business interruption, injury and death.
