I just moved into an attic apartment and whenever the temperature outside gets to be hot, 85+ degrees or so, my apartment starts reeking of TAR. Any ideas about how to fix this problem, or what will be required to fix this problem? I suspect the TAR odor is coming from the roof tiles. Maybe a can of air between the attic ceiling and roof would do? I'm also home most of the time and require air conditioning for a medical condition so ventilating this place will get to be expensive. Any suggestions regarding that? Thanks in advance if you can help!
