Purpose of This Web Site. The purpose of this Web site is to provide ground snow load analysis information and data gathered from all 50 States. Each state has a listing of building code and applicable guidelines for snow loads, as well as details about where the snow load information may be found or purchased.

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.

Roof Load Zone Map Each manufactured home must be designed according to the federal Manufactured Home Construction and Safety Standards at 24 CFR 3280, commonly called the HUD Code. The HUD Code stipulates, at §3280.305(c)(3), that the home shall be designed and constructed to conform to one of three roof load zones.
I find that code commentaries do a good job of explaining the basis of a code requirement, and in the case of Section R301.6, the commentary suggests that 20 psf is a pretty severe live-load condition and is most likely to be concentrated in a small area of the roof, as with a stack of shingle bundles.
Where uniform roof live loads are reduced to less than 20 psf (0.96 kN/m 2) in accordance with Section 1607.12.2.1 and are applied to the design of structural members arranged so as to create continuity, the reduced roof live load shall be applied to adjacent spans or to alternate spans, whichever produces the most unfavorable load effect.See Section 1607.12.2 for reductions in minimum roof ...
Common Design Loads in Building Codes Notation: A = name for area ... r = live roof load symbol LRFD = load and resistance factor design R = rainwater load or ice water load ... (see code) AASHTO lane loads should also be considered where appropriate.
When the I codes were first adopted in NE PA, we chose to use the snow load of 50 as a default, since it roughly equals 38.5psf design load and we allowed a 30psf design load under our old code. After receiving much flack from the contractors, I had a study done on the the 2 areas that are being heavily developed and suprisingly enough the ...
