So you’re trying to fall asleep and something is just taping outside right after it rains. Where is it coming from and how do I stop it! You’re not alone, many light sleepers complain of a noise that comes from a single droplet of water smashing down onto an echo-e piece of metal producing that awful tap. It probably doesn’t help if you have thin walls. Rest assured, there is a fix for that. It can occur on one story downspouts, and gets louder as the downspouts get taller. What can be done? Stick a sock in it.
