All About Chimney Caps

When it comes to protecting your fireplace system, there are a number of different chimney parts that play an important role. The chimney cap, however, is one of the most important parts of the chimney and is responsible for protecting the chimney and fireplace from animals, moisture, and debris.

Because chimney caps cannot be easily examined from street level, many homeowners are not familiar with their importance. Without a functioning chimney cap, however, your chimney and fireplace system can quickly and easily become damaged.

What is a chimney cap?

Chimney caps *are metal covers that are designed to protect both the top of the chimney and the entrance of the flue. Made out of materials such as stainless steel, chimney caps have mesh or wire sides that allow smoke out while preventing larger debris from getting in.

In addition to protecting your flue and fireplace, chimney caps are an excellent way to add a decorative finish to your chimney. With chimney caps available in a variety of styles, caps can be found to match a variety of aesthetics or rooflines.

Not all chimney caps are created equally, however. Many homes have factory built chimney caps. These chimney caps come in set sizes and materials and are designed to fit most chimneys. However, if your home has an unusual chimney or you are looking for a more unique look, you may want to consider a custom chimney cap. Custom chimney caps are built to the exact specifications and dimensions of your chimney and can be made using the materials or style of your choice.

Why do I need a chimney cap?

While chimney caps can add a beautiful decorative finish to the top of your chimney, they also serve an important functional purpose. Below are some of the ways that chimney caps protect the health and safety of your chimney and fireplace system.

Keep out animals and debris: Without a chimney cap, the entrance of the flue is open and exposed. This means that animals and debris can easily find their way in. Even a damaged chimney cap can still let animals in; small birds and mammals can squeeze through even tiny cracks, and larger animals such as raccoons can use their claws to pry their way in. In addition to damaging the chimney, debris like leaves, twigs, branches, or even stray balls or Frisbees can all cause chimney blockages that affect chimney safety and efficiency.

Prevent water damage: Just as a chimney cap keeps animals and debris out of your chimney, it also keeps water from getting in. Because water  can severely damage the masonry and metal components of the inside of the chimney, it is important that the delicate fireplace system is protected against the elements. With a damaged chimney cap, even small amounts of water can create a chimney leak that leads to damaged masonry, walls, ceilings, and even mold or mildew growth in the chimney.

The chimney cap is one of the most important parts of your chimney. Because of this, it is extremely important that you have a well-fitting and well maintained chimney cap.
