How Does a Chimney Cap Help My Chimney?

How Chimney Caps Help My Chimney Photo - Chicago IL - Aelite Chimney Specialties LLCYou may wonder why you need a chimney cap, but in order to work efficiently and safely, your chimney needs several important components, including a high-quality chimney cap. According to the Chimney Safety Institute of America (CSIA), a chimney cap is the most economical way to prevent water penetration of your masonry chimney. This essential chimney component helps in other ways as well. Aelite Chimney Specialties offers chimney cap sales and professional installation services to the Chicago area, and we would like to tell you more about the functions of a chimney cap.

Prevents water leaks

Sitting at the top of your chimney, the chimney cap covers the opening to keep water from rain and snow from getting into your home through the flue. This water will run off the cap away from the chimney and roof to help you avoid water damage that can be extensive and expensive.

Keeps wild animals out

Many types of chimney caps come equipped with mesh metal sides that serve to stop birds, squirrels, raccoons, and other wild animals from getting inside your chimney. These wild animals can confuse chimneys with hollow trees and choose one to make a nest for the winter. This can lead to damage, insect infestation, and possibly even the animal becoming trapped and dying inside your chimney. You need a good chimney cap to prevent these critters from entering.

Avoids accidental fires

The mesh metal sides that keep out birds and animals can also help prevent accidental fires. Also known as spark arrestors, the meshing stops hot sparks and embers from jumping out of the top of the chimney to land on your roof or your yard.

Improves the draft in your chimney

You can find certain types of chimney caps that have special vents that direct the wind to pull smoke, gases, and the other byproducts of combustion out of your chimney as the draft is supposed to do. If you are having trouble lighting a fire or having smoke fill the room when you do light a fire, this type of chimney cap can be very helpful.

Aelite Chimney Specialties carries a wide variety of chimney caps in various shapes and sizes. Whether you prefer copper, stainless steel, or another metal, we can help you find the perfect cap for your chimney.

Why Buy Your Chimney Cap From Chimney Professionals

You can trust Aelite with your next chimney cap!

Our staff at Aelite Chimney Specialties understands how important it is for our customers to save money however they can, but there are times when it is worth spending extra money for quality products. One of these times is when you are purchasing a new chimney cap. While it may seem like a great bargain to buy a chimney cap from a big box store like Costco or Sam’s Club, you will most likely end up spending more money on repairs and possibly even the replacement of that cheap cap that you thought was such a good deal. We would like to tell you why you should always buy your chimney cap from certified chimney professionals.


The chimney caps that are sold at the big box discount stores are inexpensive for a reason. According to Do It Yourself, the chimney caps you will find at big box discount stores are generally made from galvanized metal, which means they are more likely to become corroded by rusting. Galvanized chimney caps can even cause damage to the interior of your chimney when they become rusted. At Aelite Chimney Specialties, we sell chimney caps that are constructed from higher quality metals like stainless steel and copper. We find these metals do not rust as easily and provide long-lasting durability.


When you purchase your chimney cap from a store like Costco, Sam’s Club, Home Depot, etc, you will most likely be on your own to install the chimney cap. While this may seem like an easy job, installing a chimney cap actually takes knowledge, experience, and precision to be sure your chimney is adequately protected from water leaks and animal invasions. If you buy your chimney cap from Aelite Chimney Specialties, you can trust our certified chimney technicians to properly fit the cap on top of your chimney. They will also ensure the cap is securely fastened to the chimney so that it will not blow away in a wind storm.


Every chimney cap sold by Aelite Chimney Specialties comes with a lifetime warranty. We also provide warranty coverage of our professional chimney cap installation services. You want to be fully covered by an extensive warranty when it comes to your chimney cap in case you need repairs performed to fix damage. Generally, the big box stores will not offer an extensive warranty coverage with the cheaper chimney caps they sell, and this means you will have to pay for the repairs to the inevitable damage that occurs to an inferior cap.

The Importance of a Chimney Cap

Your chimney and venting system is made up of different components with varying functions, and a chimney cap ranks high in importance as one of these components. Serving several purposes, a properly-installed chimney cap will prolong the life of your fireplace and chimney system. Not everyone caps his chimney as some people feel it is an unnecessary expense; however, the cost of a chimney cap and its professional installation is much less expensive than the costs of the repairs of the damage that can be caused to an uncapped chimney. As Chimney Safety Institute of America (CSIA)-certified chimney sweeps, we at Aelite Chimney Specialties are committed to keeping your chimney and venting system working safely and properly. We would like to share with you a few reasons why a chimney cap is such an essential part of your fireplace and chimney system.

A Chimney Cap Keeps Wild Animals out of Your Chimney.

Every winter when birds, squirrels, and raccoons are looking for a warm, safe place to nest during the cold months, some of these animals can mistake your chimney for a hollow tree and use your chimney as a place to hibernate. Once they move in, it does not take long for a family of animals to make their new home in your flue. For example, squirrels can build a four foot deep nest in less than 24 hours. Animals in your chimney can be the cause of several problems. The nesting materials can be a fire hazard, and a nest can also cause a chimney blockage. If the exit of your chimney is blocked, smoke and toxic gases are trapped inside and are forced back into your home, which causes soot and smoke damage as well as the possibility of carbon monoxide poisoning. Birds and animals can become trapped within your chimney and eventually die. This will create a horrible odor within your home, along with a possible bug infestation. There is also the chance the birds and animals will get into your house through the fireplace and cause damage to your home. A chimney cap with mesh siding will keep these animals from intruding into your chimney in the first place.

A Chimney Cap Protects Your Chimney from Water Penetration.

One of the most important jobs of a chimney cap is to divert water away from your chimney. Water is the number one enemy of a masonry chimney because it can cause major deterioration to its structure. The most damage occurs during the freeze-thaw process in the winter. When moisture trapped inside the bricks freezes, it expands as it thaws, which causes cracks and other damage. Known as spalling, this may affect your masonry work, your chimney liner, and your chimney crown. A properly fitted and installed chimney cap is one of your best defenses against damage from water penetration of your masonry chimney.

A Chimney Cap Prevents Sparks from Jumping from the Chimney and Starting a Fire.

Without a chimney cap with mesh sides, sparks can escape from your chimney and land on your roof or be blown away by the wind to land in your yard, trees, or even on your neighborís roof. Even a tiny spark can ignite a fire. Capping your chimney is the best way to keep the sparks in your chimney.
