We bought a house last December. It's our first home. We went on holidays, came back and there was a tiny bit of water dripping down on a corner in the bathroom. It dried fairly quickly so I thought maybe it was condensation as dh had just had a shower (wishful thinking). Today it's raining so I went and had a look and it's there again. We replaced the ridge tiles on the roof a couple of months ago but can't afford to replace the whole roof. The wc on the other side of the wall is fine. It puzzles me that the water is not on an exterior wall. The exterior wall is the one with the window. There's an alcove on the other wall hence the weird shape. Any ideas?
