Considering all of these effects, a new zoning procedure for low-sloped roofs for buildings with h 60 feet was developed. Thus starts the time when practicing engineers learn the new provisions of the Standard and how they apply to their practices. This table is based on 140 mph wind speeds and a 45-foot mean roof height.
