1994 ubc snow loads

[BLSPAM]

I am currently looking at the capacity of a roof designed in 1995 for the addition of mechanical equipment. Has anyone compared the snow load of 1995 UBC to todays IBC 2012?

The project is in St. Cloud Minnesota. Pg = 50 psf

I attached the section from the 1994 UBC on snow. Hopefully the local code had more information than this.
