Why does my chimney leak when it rains?
One of the most common reasons for rain to leak into a chimney is physical damage or wear and tear to the chimney. The portion of your chimney that extends outside of your home faces near constant exposure to the elements, including rain, snow, high wind, and sun exposure. Over time, these elements can break down the materials of your chimney, causing cracks and gaps that allow rain to leak in.
Chimney flashing deterioration is a common problem that can occur over time. Metal flashing can rust or otherwise weaken from the elements, and caulking around the flashing can become loose, which can cause problems for the homeowner. Getting up on the roof to inspect the chimney can be dangerous, so it’s important to be aware of these potential problems.

4. Use a hammer or screwdriver to nail or screw the flashing into place.
5. Finally, use a putty knife or caulking gun to apply sealant or caulk around the edges of the flashing to create a watertight seal.
There are a few different ways that you can repair chimney flashing. The most common and least expensive option is to use caulk. If your chimney is leaking, you may need to use a sealant. You can also use a putty knife to remove any old sealant and apply new sealant. If your chimney is structurally unsound, you may need to replace the entire chimney.
