Snow load guides
Ground snow loads, explained for the two people who ask about them: the homeowner who wants a trustworthy number, and the engineer who needs the methodology.
For engineers and owners
Ground snow load case study: what it is, and when you need one
Why the map says “CS” in mountain areas, what changed with ASCE 7-22, how a site-specific study is done from nearby weather stations, and what a building official looks for.
For homeowners
How much snow can my roof hold?
Why the same depth of snow can weigh up to seven times more or less, how roofs are actually rated, the warning signs of overload, and how to find the design number for your address.
For engineers
ASCE 7-22 ground snow loads: what changed
The move from the uniform-hazard map to reliability-targeted values, the fate of case-study zones, and where site-specific studies still fit.
