Chimney CapA chimney cap is a layer of metal or concrete around the top of the chimney. The purpose of a chimney cap is to protect the upper bricks from severe weather. A metal chimney cap is used for wood burning stoves. A metal chimney cap is needed to keep rain from falling down the chimney, to keep birds or other small animals from nesting inside, and to prevent moisture from entering the chimney. A concrete chimney cap is also used to keep water and animals out of the chimney. Disadvantages to concrete chimney caps include: allowing too much of a draft and discoloration of the chimney's exterior. It is important to get a chimney cap when the chimney is made. This ensures that a customized chimney cap will be included that matches the brand of the chimney. A generic chimney cap can also be bought if not included with the chimney or when there are draft problems or the cap has worn out.
