Light (81.8%) Moderate (17.0%) Case Study (1.1%)
Light — 72 counties with 1–20 PSF. Standard roof construction is typically sufficient.
Moderate — 15 counties with 21–40 PSF. Roofs need reinforced framing to handle regular snow buildup.
Case Study — 1 county where snow loads vary too much to assign one number. A licensed engineer must determine the load for your specific site.

Based on ASCE 7-22, the national standard for structural snow loads used by engineers and building codes across the US.
