Should attic space over attached garage be blocked off for proper attic air sealing and ventilation?
Pacific Northwest Region-Washington
Attic space over living space has loose fill fiberglass/no vapor barrier and is vented (double bird-hole eave intake vents and continuous ridge vent exhaust). Garage is sheet-rocked but attic space over attached garage is not insulated. Attic access is in garage ceiling.
Moisture problem evident on underside of roof sheathing. More apparent over living space than garage.
Plan to seal gaps and add insulation but curious about separating garage attic space.
