When it rains heavily outside, a dripping sound appears from the roof/attic in a room. I was so sure it was leaking in that Anticimex came here and checked, but there is no visible water seepage from the roof. When I then calmed down and focused, I realized that it sounds like it's coming from the chimney in the room. We have a masonry chimney and an insert stove. Could there be something in the chimney where the water can "get stuck" and then drip..?
Bird's nest? Wasp nest? Junk?
If it were debris or a bird's nest that the water then runs off, it should still drip straight down, and not make noise upstairs, or am I thinking wrong?
