I have a house with a hip roof and ridge vent. Had additional blown-in insulation added and have moisture problem. Discovered that my soffit is completely blocked by wood. Understand that best resolution is having continous soffit vents added, but because of expense and the difficulty in pulling back insulation and adding baffles (low attic access and compacting insulation), could adding roof intake vents fairly low work as a substitute? Or even blocking the ridge vent and adding a power ventilation fan and roof intake vents? Roof was put on about 15 years ago and shingles are showing wear. Any other solutions?
