How Much Does a Chimney Cap Cost?

Chimney Cap Prices

The purpose of a chimney is to let smoke and harmful gases such as carbon monoxide out, thereby keeping your family safe. But, problems can also arise if things are allowed to come into your chimney.

Chimney caps are designed to prevent animals, debris, and water from entering the chimney and wreaking havoc. They also help prevent roof fires and downdrafts. If your chimney doesn't have a cap, or the existing one is in disrepair, then it is paramount that you have a new one installed right away to avoid costly repairs down the road. Continue reading to learn more about chimney caps and chimney cap installation costs.

An Overview of Chimney Caps

Within the chimney itself, is a chamber known as a flue which acts as a ventilation shaft for smoke, gases, and combustible byproducts. If you climbed onto your roof and looked at the chimney, you would see an open hole, the flue, at the top. It is over the flue, or flues, if your chimney has more than one, that the chimney cap is placed.

Types of Chimney Caps

The first step in choosing a chimney cap is determining whether you have a prefabricated chimney or a masonry chimney.

  • Prefabricated chimneys are usually installed in homes built during the mid-1980s or later. Made of metal, they are sometimes called "fake chimneys" to distinguish them from traditional brick and mortar chimneys. It's advisable to use a cap manufactured by the chimney maker to ensure the best fit and performance.
  • A masonry chimney, with an exterior brick fašade, is probably what comes to mind when you think of a chimney. Masonry chimneys can be fitted with a wide variety of chimney caps.
  • Once you've determined what type of chimney you have, it's time to consider the different materials used to make chimney caps.

  • Galvanized: Galvanized chimney caps are made of steel and usually painted black. While relatively inexpensive, these metal chimney caps tend to rust, which can discolor your roof and make the cap prone to being blown off by strong winds.
  • Stainless Steel: This is the type of chimney cap most often installed by professionals. Stainless steel chimney caps are silver in color and often come with a lifetime warrantee.
  • Copper: A copper chimney cap can cost up to three times as much as stainless steel caps, but they look great and should last a lifetime. Note that it's also possible to have a custom chimney cap or decorative chimney cap made from any of these materials installed as well.
