This is my first winter in my new house and just recently noticed a great deal of condensation on the inside of my roof. In the past week temperatures have been in the -0's to -10's. I have lived in the midwest my whole life and never have seen anything like this. My house was built in 2002 and I think every thing is up to code.
You can also fit wedges to keep the overlap on the starking felt apart and allow a free flow of air

sounds like it needs some ventilation dads roof was like this and we installed some vent tiles to the roof and problem solved. before you do this check to see if you have soffit vents some times thease get blocked by people putting insulation to close to the sides of the loft needs to be a gap between the insulation and the felt all the way around the roof
