Leaks: How frustrating!

Imagine there's a leak in the house that originates somewhere in the roof, but you can't locate it with any precision as the bead of water runs along some piece of wood and the place where the drop happens is just at some other location. If it's winter, there's even snow and ice to remove and this make the chase even more confusing and frustrating. What's one to do in a situation like this?

The answer is as deceptively simple as the problem is deeply complicated: Observe very attentively, be patient, methodical and keep moving in the investigative work. There's no rush solution available; it's another test for our atrophied, 21st century patience!
