I want to roll out some additional fiberglass insulation in my attic. Currently there is loose cellulose with faced fiberglass batts placed on top of the cellulose. The facing is facing out as in the picture. My question is, can i just roll the insulation out on top of this without a vapor issue or do i need to remove the facing (if that's even possible). Thanks for you thoughts.

The facing shouldn't be there in the first place. The facing/vapor barrier should always be on the inside. ("Warm side")
Having the facing on the outside creates a moisture pocket - moisture that gets between the ceiling below and the facing above becomes trapped, and encourages rot and mold growth.
Remove the facing and then you can pile on more insulation to your hearts content. Lay it perpendicular to the existing layer.
