Strange stains on todays inspection. The soffits throughout had this dark staining which could be rubbed off. It was difficult to tell if it was dirt or perhaps a type of mold/algae growth. Have any of you seen this and what have you determined it to be?
The home had soffit vents and continuous ridge vents throughout with good ventilation/insulation in the attic.
Hard to tell from here but looks like remnants of ice backup/damming…moisture coming from behind the paint…typically, inadequate ventilation and/or insulation. Often plugged gutters promote ice backup.
