I finished two rooms in an unfinished attic, roof construction is 2x6's, roof has only two vents, length of the roof is about 35ft. long. I used R-13 to leave an air gap. I didn't know about the Styrofoam spacers, I insulated from the knee wall to not quite to the top of the roof about a 7ft. span. Since then I checked it through the crawl space and noticed that the insulation expanded and is touching the bottom of the roof sheathing. Hence, causing condensation. What can I do to correct this mistake. The roof is old so we will have to replace it in the next couple of years, in the meantime what can I do until then to avoid rot or mold?? any advice will be appreciated.
