Hey guys... I want to thank you in advance for your time and sharing your experience and professionalism. I live in Vermont. Upstairs, my roof is part of the wall structure. Last year, my roof sweat like crazy. We insatalled vinal in the eaves and proper vented the roof to the attic space. My issue seems to be in the valleys. Since they dont stretch to the eaves, I am unsure how to get ventilation. Right now, there is proper vent in there with fiberglass insulation below. As you can well imagine, the venting isn't cut perfectly and the insulation butts up tight. Will this work?
