A Homeowner Concern for Roof Repair

There is a good chance that is condensation from the A/C. Sometimes when the duct is not sealed up tightly it can produce condensation around the register and the sheetrock soaks up the moisture causing it to stain as you see in the picture.

The first thing I would ask the homeowner, have you ever noticed water leaking around the vent when raining outside? If not, then I know the roof is not the issue but instead water is getting in the air ducts from the HVAC unit or there is a condensation problem. Sometimes ice can build up in the air ducts several inches thick during the winter months and melt when the temperature gets warmer and look like it's raining inside. Also, if a home has a flat roof, the air ducts outside may need to be sealed which can also cause a leak inside. Important Note: Many times with this type of problem mold develops because of not being corrected soon enough.
