Leaking First floor ceiling.
cyberbmcd

OK, I woke up to a baffling mystery today. a leak, dripping from my dining room "chandelier" on the first floor. water steadily dripping right down the middle. Here's the mystery, there is no leak on the 2nd floor ceiling, there is no 2nd floor bathroom and the area above the chandelier on the 2nd floor is bone dry. this makes absolutely no sense to me. Any ideas? Also, I am only handy for simple household repairs like changing light fixtures, etc, I wouldn't know who to even call for this issue.

Heavy thunderstorms last night, but how could 1st floor ceiling drip and not 2nd floor ceiling?

Water follows whatever path is easiest by gravity. It could have been wind-driven into the nearest window, followed the framing down and then followed a ceiling joist. Could have followed a plumbing vent pipe (bad flashing).
Pinholes in copper can spray a fine stream a surprising distance, too, then it just follows the sag of the ceiling to the center, which is the ceiling box. Water supplies and hot water heating pipes are suspects. If it keeps on long after the rain event, it is a pipe under pressure. (if your "no upstairs bathroom nearby" assessment is correct, and the drain does not traverse the room above the leak.)

Yes, there is no upstairs plumbing other than the baseboard heat. Since the weather has been about 80 every day it's not likely a plumbing issue, and besides the baseboard pipes wouldn't likely be traversing the ceiling as likely as coming up through the walls. I've been told it may be a bad flashing more than once, and that my dormers may be the culprit as well. All I know is it sounds like it's going to cost me a lot of $$$$$. Marvy...........

When it comes to water leaks, procrastination will cost you much more. You have to solve them quickly and efficiently. Don't think about how much it will cost you to fix the leak, but think how much it will cost you if you don't.

You have to follow the water back to the source. Get a moisture meter and start testing the drywall on the outside wall directly opposite the ceiling box. Find the wall stud bay with the highest moisture reading; take down the drywall and follow the wet insulation. If it's wet all the way up, then it's in the roof. If it stops at a particular height, there you are, find where it's coming into the wall cavity. Then you can begin to look outside for the flaw. Don't worry about the drywall, and you need to rip out the wet insulation anyway because of mold.
