I have this nice new stain on my bedroom ceiling, I have a 2nd story bathroom above it so I figure this has to be some sort of water issue? No obvious signs of anything in that bathroom though. Anybody have any plumbers they'd recommend?

Is there attic space up there? Any HVAC equipment?

There is some attic space that wraps behind the back of that bathroom now that you mention it. Didn't climb back in there. I'll have a look as soon as I can get back home, had a wild work day and took this picture on my way out the door when I noticed it for the first time. Really hope I'm not compounding the issue dragging my feet for a few hours.

My attic problem was HVAC related, but who knows with water. I'm in Frisco and use Dennis Rollins. 4698344741

We've used them multiple times and they are always honest and very well priced

If it ends up being HVAC related,
