Finished Attic with Metal Roof
I have a finished attic with a metal roof. The roof pitch is about 14-12 and there is no venting at all. I have box gutters with a soffit, but no vents. The finished attic has drywall, wool insulation in a plastic bag, then planks every other row, then the metal roof. There isn't really a knee wall. Just about 10" between the floor and slope of the roof.
Obviously my drywall keeps cracking because there is moisture. I have cut out sections to verify that the roof doesn't leak. How do I vent an attic like this? Can ridge vents be installed on metal roofs? Right now there are zero vents on roof or soffits.
