Moisture staining on the common wall between the house and garage. I noticed some of the stains were right in line with the wall studs.
I checked the roof in this area (where the garage roof meets the wall of the house) and it appeared to be fine. No visible flashing - vinyl sided.
I checked the stains with a moisture meter before going into the house and one of the stains in the drywall was at 20%. It started to rain while I was doing the inside portion of my inspection. When I was packing up to leave I checked the same stain that was 20% and found it to be 50%.
I recommended a licensed roofer evaluate and repair as needed. The buyer contacted me and said the roofer didn’t find any issues.
This has to be coming from the roof. Anyone have experience with the same type of issue - stains in the common wall nothing visible in the attic or on the ceiling?
I suggested removing the drywall in the garage to trace the stain to the leak. Any other advice is appreciated.
Have a blessed day!
