I have been asked to look at a roof that has serious condensation issues. It has a purlin system with a 29ga ag panel. It was a reroof with a flat roof material for the first roof.(3/12) Ridge vent was cut into the house, the cut penetrated the closet space. (no insulation?!)The hole was plugged. The metal roof has been opened at the bottom and ridge vent at the top. Still condensation. The kitchen has a commercial stove with constant gas pilots. The inside ceiling is tounge and groove, so the easiest way to insulate would be from the outside. If a vertical purlin system with horizontal purlin system was installed what R-Value would need to be reached to stop the condensation? Is there a better way to solve this?
