I have a newly constructed home in Northern New York. Over the weekend the my metal roof was dripping all over the upstairs. It was 20 degrees out and 75 inside with the wood stove going. I installed the metal roof on strapping with no moisture barrier. The roof is insulated with r19 faced. The upstairs is unfinished. I vented the roof using a ridge/soffit vent. Is there a way to solution this without pulling the whole roof off?

Look for undue sources of moisture inside the home. Another solution would be to spray the underside of the roofing with closed cell urethane foam insulation.

If I sprayed the underside of the roof with closed cell urethane foam insulation does this come in contact with the metal roof? Will the proper vents provide enough ventilation to the ridge vent?

I would suggest talking to the insulation contractor for their opinion. Yes, the foam would be on the back of the roofing. It would be nice to keep the vents open but I would spray the entire underside of the roof deck.
