This module is an implementation of the ASCE 7-22 method of determining Flat Roof Snow Load, Sloped Roof Snow Load, and Snow Drifts on Lower Roofs, and Snow Drifts at Roof Obstructions. The Snow Loads module does not currently address the calculation of unbalanced snow loads, rain on snow surcharges, or sliding snow surcharges.

 

 

Flat Roof Snow Loads

Collects values for determination of the flat roof snow load in accordance with ASCE 7.

 

 

Sloped Roof Snow Loads

Collects parameters to calculate sloped roof snow loads in accordance with ASCE 7.

 

 

Snow Drifts on Lower Roofs

The input form collects values for all of the necessary parameters to determine the windward and leeward drifts in accordance with ASCE 7.

 

 

Snow Drifts at Roof Projections

The input form collects values for all of the necessary parameters to determine drifts at roof projections in accordance with ASCE 7.
