We are having trouble with mold and condensation after years of the roof replacement. They "missed" adding a ridge vent the first time around, and we had to pay to get it done. The problem has not resolved itself. They came back and wanted to punch 12 O'Hagin vents to solve it. I've been told numerous times that that will do nothing. Judging by the laziness of their work, I would stay away.

We’re sorry to hear you’re still experiencing condensation and mold concerns. We do want to clarify, however, that the roof itself does not create condensation inside the home. Indoor condensation is typically caused by moisture generated through everyday activities such as showering, cooking, drying clothes, and other sources of humidity.
Proper ventilation will do something positive for your home. Including ridge vents and O’Hagin vents helps moisture and warm humid air escape through the attic and improve overall ventilation.
