If you own a home with a fireplace or wood stove, you’re probably familiar with the importance of regular chimney repairs and maintenance. One of the essential components of a healthy chimney system is the chimney crown. But what is this and what purpose does this crown actually serve? And more importantly – how long will your chimney crown last?

One of our core values here at Wolfman Chimney & Fireplace is education, not just for our certified chimney sweeps and staff, but for our customers too. We believe that helping our customers understand their chimneys and fireplaces better helps them make informed decisions when it comes to maintenance and repairs. Let’s take a deeper look at chimney crowns, how they work, and why you need to keep them in good condition.

What Is a Chimney Crown?

Simply put, a chimney crown is a slab of concrete that sits on top of the chimney stack, covering the flue or flues and protecting the masonry below from rain and other elements. Chimney crowns come in a variety of shapes and sizes, depending on the design of the chimney and the number of flues it has. In order to be effective, your chimney crown should be designed to have a downward slope, to allow for better water runoff.

If your crown is damaged, count on the certified professionals at Wolfman Chimney & Fireplace to use high-quality, reliable materials rebuild or restore it back to its former glory.

How Does a Chimney Crown Work?

Your chimney crown’s job is to prevent water from entering the chimney system. When it rains, water can seep into the cracks and crevices of the chimney stack, leading to water damage and other issues. The chimney crown sits on top of the chimney stack and creates a barrier that prevents water from entering your flue.

In addition to protecting your chimney system from water damage, your chimney crown also works with the chimney cap to prevent debris from entering. Leaves, twigs, and other debris can accumulate on top of the chimney surround and potentially block the flue, leading to issues with smoke and carbon monoxide buildup.

Chimney crowns play a crucial role in protecting the chimney system and your home from water damage and keeping unwanted debris out. Without a properly functioning chimney crown, water can seep into the chimney and cause significant damage to the masonry and other components of your home’s chimney system.

What’s a Chimney Crown’s Typical Lifespan?

A well-built and properly installed chimney crown can last anywhere for 20 – 50 years. However, many factors can affect its lifespan, including… 

  1. Weather Conditions: Harsh weather, such as heavy rain or harsh winds, can cause damage to the chimney crown over time.
  2. Construction Materials: The quality of the materials used to build the chimney crown can impact its durability and lifespan.
  3. Installation: If a chimney crown is not installed correctly, it can develop cracks and other damage, leading to a shorter lifespan.
  4. Maintenance: Regular maintenance and cleaning can help extend the life of a chimney crown.
  5. Chimney Usage: Frequent use of a chimney can cause wear and tear on the crown, leading to damage and a shorter lifespan.

Typically, when we see chimney crowns needing some sort of repair or partial rebuild within the first 20 years it is due to the quality of materials used or how it was built in the first place. When it comes to your chimney crown, quality matters at every stage.
