Why do some chimneys not have a cap?
Chimneys are complex structures and are always exposed to the weather. They aren’t designed to go without chimney caps, but not everyone knows this. Because chimneys are always exposed, rain water, leaves, feathers, and all sorts of things can fall into them and build up or cause damage.

How does a chimney not let rain in?
How Do Chimneys Keep Rain Out? The most important part of a chimney that keeps rain out is the chimney cap. Chimney caps are a cover for the top of the chimney that usually has a slight slant. This slant allows rain to slide away from the chimney.
Is rain supposed to come down the chimney?
Rainwater trickling into your fireplace is not normal. In fact, it is a telltale sign that there is an issue within your chimney system. The chimney is a much more complicated structure than most people realize. For this reason, pinpointing the exact source of the leak can be challenging.
How do you cap an unused chimney?
Apply a bead of butyl rubber caulk around three sides of the chimney at the top, and set the cut piece of metal on the chimney so the edges line up with the caulk bead. Press the metal into the caulk. The goal of this metal cap is to prevent rain from coming in, but it shouldn’t be an airtight seal.
Do wind directional chimney caps work?
These chimney caps help your fireplace vent properly by forcing smoke upward and out of your chimney. The air velocity created by the wind reduces the static pressure above the chimney, creating a partial vacuum and forcing the smoke inside the flue upward. You can expect a better updraft the harder the wind blows.
