My wife spotted these cracks in our ceiling and we're both now trying to figure out how to go about fixing them. How do we know if it's a structural issue or just a retouching of the paint issue.
Attached are a couple pictures.
drywall ceiling with popcorn texture
the ceiling cracks are located in the top most ceiling (attic right above it)
house is 20 years old and in otherwise good condition.
recently had a new furnace with whole-house humidifier installed.
Any help would be greatly appreciated.
