ASCE 7-22 Snow Load Formulas

$$P_f = 0.7 times C_e times C_t times I_s times p_g$$

$$P_s = C_s times P_f$$

Ground snow loads ($p_g$) are converted to flat roof design pressures using exposure ($C_e$), thermal ($C_t$), and importance ($I_s$) factors, reduced by slope shedding factors ($C_s$) on steeper roofs.
