Re: Insulating Attic Ceiling
Simply adding insualtion to the underside of the roof doesn't give much advantage --- you would need to completely insulate *all* exterior surfaces of the attic -- if there are gable end walls they also need to be insulated.

Considering it would be more square footage to apply insulation to all exterior surfaces in the attic than would take to lay it down on the floor of the attic.
It would be a different story during the renovation stage when a different approach could have been taken at that time.
Insulation is only half the equation , ensuring the penetrations from plumbing , electrical , gaps in framing, into the attic space are well air sealed is the other important half of the equation.
By the way --- I also live in a c-c-cold climate.
