Pg = 5 psf
Pg = 5 psf
(OP)
Since I work mainly in northern climates I have a couple questions when dealing with snow loads where Pg = 5 psf.
According to ASCE 7-02, Pf = (I)Pg = 5 psf but then I have to add 5 psf rain on snow surcharge. When calculating drift, do I use Pg = 5 psf and Pf = 5 psf or Pg = 10 psf and Pf = 10 psf or something else? I am confused!

I believe you mean flat roof snow load Pf. Because rain on snow surcharge is not required when you use drift loads. Although I do agree that the design load (S) would be the Pf + rain on snow surcharge.
