In my area, 6" is nothing! However there are several factors to consider!
I have flat roofed, attached garage that has a laundry in one end. The ceiling joists/rafters span 15 feet and are made from 2X8" #1 grade white spruce.
I have had as much as 36" of snow on there, and all has been well for 30 years.
To make a proper judgement in your case, the size and the length of the rafters and what type of lumber has to be known.
If you are in doubt, it is a good idea to remove the snow.
I use an electric snow shovel for this purpose. A regular shovel is likely to gouge the roofing and then you will have a major problem when the snow melts.
