Wisconsin Roof Snow Loads TM


Use our Wisconsin Roof Snow Loads map to easily determine the roof design snow load (Wisconsin Administrative Code: SPS 321 SubChapter 2) for any location in the State of Wisconsin. Wisconsin has not adopted the International Residential Code (IRC) and utilizes its own Uniform Dwelling Code (UDC) for all residential structures. You can click on the map below to find the minimum roof design snow load for that location.

All commercial buildings and structures should use the ground snow load values from the 2009 IBC and not the residential design values given below.
 
* Roof design snow loads derived from Figure 321.02 of the Wisconsin Administrative Code. Local codes and ammendments may govern,verify with local building department or jurisdiction.
 

Use our Roof Snow Load Calculator to determine your design roof snow loads.
