Can't say I have seen this before. Older home, insulation on the attic floor, and then they went and added firberglass batts. Would you be concerned that the batts are in touch with the deck? BTW, the batts are also blocking the continuous ridge vent(s). No soffit vents, 2 gable end vents. Click to Enlarge 45.1 KB Click to Enlarge 46.94 KB
