The wall or ceiling interior surface will be cooler where the "Ghosting" is particulates sticking to the wall or ceiling in areas that are colder than others due to thermal bridging of the framing and therefore slightly damp from condensation. Sometimes where a porch roof is attached to an existing building or building roof, the porch roof is at a lower slope than the roof on the main building. In turn, leaks from ice damming or accumulated snow in that area can dampen the ceiling that in turn invites accumulation of dust or soot stains. focusing on the cause of various interior wall and ceiling stains and explains how to recognize thermal tracking, thermal bridging stains, Ceiling stains over lights: Alan Carson adds that When left for long periods of time, these can cause a permanent stain.

Apparently, humidity is causing the dark lines. Thermal tracking or "soot tracking" (also called thermal bridging or ghosting stains) such as shown in the photograph at the top of this page may be found wherever moisture condenses on cool building surfaces. Warm moisture-laden air touches the cooler surface of a building wall or ceiling, giving up some of its moisture to the surface as condensation.Also see AIR MOVEMENT in BUILDINGS, As air moves The differences between thermal tracking and indoor dust or stains that are coming from the HVAC system include: So it looks as if your daughter's in-laws are probably quite correct - it's indoor dirt, or more technically, airborne dust and debris being blown out of the air supply registers.

The narrow dark stains on the ceiling show the location of ceiling joists, and the wide black sooty stain in the upper left of the photo shows where ceiling insulation is less or has been omitted entirely.
