Wisconsin Roof Snow Loads

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.
