Begin at the wet spot and go uphill

Something to check

Some time ago we had a ceiling leak in a room that is under the flat roof part of the house. When we looked at the roof area above the leak there seemed to be nothing wrong. The roof looked perfect in every direction. Then it leaked into a closet (ugh) a few feet away from the first spot. A long time (and a lot of damage) later, we found a very good professional roofer to finally figure it out. Rainwater was entering at a spot at the very edge of the roof where there was some flashing problem, 10 or 12 feet from the wet spot in the ceiling, and then working its way in between layers of roofing material and along a ceiling joist (hidden, of course), and dripping into the house when and where it was ready. So you might go out and check all the flashing and tie-in edges where things meet and see if you can find a little defect. It doesn't take much of a wound in your roof to let in a lot of water damage. Good luck finding the problem.
