Just wondering if there is an easy way to tell if water damage on the celing is a result of a roof leak, or condensation build up in the house.
Here are some pictures: https://photos.app.goo.gl/6w9uajoAcbcgYpbT8
I drilled a hole from the bottom and stuck a wire so i can be directly over the damged area.
The worst of it is in the corner but there is a bit of mold along the wall too.
Because the damage is in the corner, its very difficult to see the draywall/roof from the attic. However with the limited pictures i managed to snap it looks pretty dry.
I did order a moisture meter, and plan on testing both sides. Is there any thing else i can look for?
This is an older house, with no kitchen exhaust fan.
