I have a second floor bedroom that does not have attic space above it, just the roof. I remodeled a several years ago and insulated the ceiling between the rafters. Shortly thereafter we had our roof redone. The roof contractor said we should not have insulated the ceiling because it could create moisture and lower the life of the shingles. A recent episode of the show showed the crew insulating roof rafters. I am confused. It is time to do some renovating and I am not sure if I need to remove the insulation which would require a complete tear out of the ceiling, drywall included. Any suggestions? I live in Northeast Pennsylvania and we usually have snowy winters. The roof for this room faces north.
