No. For conventional construction, the 1 and 2 family code provides a prescriptive (using figures and tables) method to determine roof member sizes. The roof snow loads used to develop these tables are derived from ground snow loads. The nomenclature and approach changed slightly from the 6th to 7th code edition to better conform to the International Code Council approach.
