We had USA insulation blow insulation into our attic space back in 2017. What they did was blow insulation over the soffits without putting in baffles. They piled insulation up to the point NO air could get through for circulation. The moisture build up happens in the warmer and hot months and temperatures… making this process slower to happen. Now our sheathing is rotted and needs replace. They of course are denying fault. Our roof was replaced 2016 one year before the insulation was installed. It may be too late for us but save your money and home by not having them do anything to your house. This work aas done by the Columbus Ohio location.
