Your chimney is more than just an elongated window sitting on top of your roof, and it’s more than just a portal from inside your home. It’s a machine that’s used to generate airflow, which is needed for fuel combustion. Hot air from the fire inside a fireplace rises through the column of a chimney, which creates a draft that pulls more air into it (thus feeding the fire). So, in that sense, your chimney is more complicated than it appears. Like any other machine, it will need to be inspected and maintained on a regular basis. 
The Parts of a Chimney
There are seven basic parts of a chimney, with each one playing an important function. These parts include the following:
- Chimney Flue — This is the vertical chute through which combustion materials leave the home. Older homes may only have masonry bricks that can be seen from above the roof line inside the flue, but modern chimneys are required by law to have a flue liner (which is usually made of clay tiles).
- Chimney Liner — This is an important part of your chimney, because it protects any combustible parts of your home from the extreme temperatures that are created by the fires inside fireplaces and wood stoves. Even if the smallest crack develops inside a liner, it needs to be repaired before it can be used again. A new liner may sometimes need to be added because a new stove or fireplace is being installed, but it must be a good fit for that particular appliance. Otherwise, it won’t produce as much heat (all while the amount of pollution increases).
- Chimney Cap — This particular component will have to be added because it doesn’t come standard with a chimney, but it’s an important accessory. A chimney cap will keep rain, debris, downdrafts, and animals from getting into your home. It will also serve as a spark guard for hot embers, which will keep fires from starting on your roof.
- Chimney Flashing — This is located at the point where your chimney and roof meet, and its purpose is to prevent water from going through the roof and damaging your home. The flashing tends to rust and wear out more quickly than other parts of your chimney, so it should be checked regularly to make sure there’s nothing wrong. Even something as simple as a rusted nail can result in a roof leak, which can lead to extensive damage to your home.
- Chimney Crown — This is the cement part that’s located at the top of your chimney, and it keeps water from getting into the entire system. If the crown becomes cracked, it needs to be repaired or replaced as soon as possible.
- Damper — The two metal plates located above the firebox make up the doors of the chimney damper, and it must be opened before a fire can be started. After the fires goes cold, the damper should be closed to prevent heat loss up the chimney. It should also be replaced if it becomes rusted or can no longer maintain an adequate seal.
- Smoke Chamber — This is located between the damper and the flue. It’s also where the byproducts from the combustion process are compressed into a smaller space so they can make their way out of the chimney.
Be sure to speak to a professional for more information.
Signs That Your Chimney Needs to be Repaired
Your chimney system is there to protect you and your family, and keeping it maintained can go a long way toward preventing house fires. While it’s standard practice to inspect chimneys on an annual basis, there’s no guarantee that problems won’t come up between then. You can let a professional know if any parts of your chimney have gotten damaged or don’t seem to work properly.
Here are some of the signs that you’re in need of chimney repair:
- Rain, animals, and debris are getting into your flue.
- Your chimney crown is cracked.
- The bricks located on the sides of your chimney have been affected by water penetration.
- The mortar between your chimney’s bricks has been damaged (which may be in the form of cracks or chunks that are falling out).
- Your flashing is damaged or is pulling away from the chimney bricks and roof flashing.
- Smoke gets into your home.
