I think I would be starting to worry about the load also. You have what is called heavy snow. Lots of moisture in it.
I looked up the code and it should be 40 lbs/sq.ft. minimum.
Remember, snow is a live load. You also have to add to this the dead load, which in your case are 2 layers of shingles, and your sheeting. I would clean the snow off my roof if I were you.
