Old Mossy Horns
DRS, no way to say for sure without seeing it but your problem may be as much due to warm air from inside the living space getting into the attic as lack of ventilation. Kinda like a glass of tea, when warm air hits cool metal it will cause condensation(sweating). I've pulled rolled metal roofing off of 100 year old farm homes and put the metal right on the existing purlings, no barrier at all, with no sweating problems.... but..... if there's a way for warm air from the living area to get into the cold attic it'll drip in that area...
The contractor is ranked on of the best in the country. We have had air quality professionals and engineers look at the problem. We have had the walls sealed to the attic, more insulation added to the attic and under the floor sealed. We monitor the temps and humidity of the living area and attic, recording these daily. It has everybody stumped. I have to say the contractor has tried to help solve the problem. Now we are talking with the contractor about providing the labor and us the material to tear off the entire roof and replacing it all. Might try insulating the under side of the roof between the rafters, first though. One problem is there is only a few months out of the year to tell if the work done helped. Heck, the roof/structure may last my lifetime. Just really don't know what to do, that is what makes it so frustrating.
