You may have heard of a chimney crown, but have you ever wondered what it actually does? This small but mighty component is an essential part of your chimney system, and it plays a crucial role in keeping your home better protected and warmer. Let’s explore the importance of a chimney crown, its functions, and why it’s essential to keep it in good condition.

What Is a Chimney Crown?

In order to understand what exactly a chimney crown does and the role it plays in your home’s chimney system, it helps to understand the main components of your entire setup. When it comes to chimney systems, there are some basic components that most chimneys have…

  1. Chimney Flue Liner: This is the vertical channel that helps gas, fumes, and other combustion byproducts safely exit the chimney and stay out of your home. Liners add an additional layer of protection for your home against the high temperatures that result from using your fireplace, wood stove, or furnace. 
  2. Chimney Cap: Chimney caps are what you typically see at the very top of your chimney. They are usually made of copper or stainless steel and can be custom designed to meet your needs. They act as barriers to keep unwanted water, outside debris, and pests out of your chimney and home. They also serve as a spark guard that protects your roof from hot embers.
  3. Chimney Crown: Crowns are the cement slab at the top of your chimney. They should have a downward slope that helps to deter water from entering your chimney system.
  4. Chimney Flashing: Flashing are the metal pieces you will see at the base of your chimney where it meets your roof shingles. Flashing acts as another layer of protection for your roof and chimney against water entry. 



5. Smoke Chamber: The smoke chamber is located between your chimney flue and damper. The smoke chamber’s job is to compress and funnel combustion byproducts before they exit through your chimney flue liner.

6. Damper: The damper has metal flaps located above the firebox that must be opened before you start a fire in your fireplace. When you are not having a fire, keeping the damper doors closed helps prevent heat loss and downdrafts.

Each component of your chimney system serves an important role in helping your chimney work effectively and keeping you and your family safer. Your chimney crown is specifically designed to act as the main barrier between your chimney and the outside elements.

When looking at your chimney, you can recognize the crown as the part that sits at top, is typically made of concrete or metal, and should have a slope to ensure effectiveness to shed water. If your chimney crown is completely flat then it won’t be able to do its job, which is to protect your chimney’s structure from water damage and prevent water entry and premature damage. 

How Does a Chimney Crown Protect Your Chimney?

A properly designed and installed chimney crown is designed to slope downward away from the chimney flue, allowing rainwater to flow away from the chimney and preventing water from seeping into the chimney structure. Your chimney crown also acts as a barrier to prevent animals and debris from entering your chimney flue, which can cause blockages and potentially dangerous situations.

Since your chimney crown is designed to act as the first line of defense against rain and other potential hazards, ensuring that yours is built with high quality materials and properly installed is a must. At Wolfman Chimney & Fireplace, you can trust that our CSIA certified chimney technicians will use the best materials and our high skill levels and expertise when it comes to all of your chimney crown needs. 

How Can I Take Care of My Chimney Crown?

Prevention is key when it comes to maintaining and taking care of your chimney crown and the rest of your chimney system. At Wolfman Chimney & Fireplace we recommend that you have your chimney and fireplace inspected and cleaned at least once a year. This allows our knowledgeable and experienced chimney technicians to spot potential issues early on, before they lead to other, more costly issues.

A well-maintained chimney crown offers several benefits, including:

  • Protection from water damage: A properly functioning chimney crown prevents water from seeping into your chimney structure and causing damage, such as rust, mold, corrosion, wood rot, and deterioration of the mortar and brickwork.
  • Prevention of animal entry: The crown acts as a barrier to prevent animals from entering your chimney, reducing the risk of blockages and potential safety hazards.
  • Extended lifespan: A well-maintained chimney crown can prolong the lifespan of your chimney by preventing damage from water and animals, reducing the need for costly repairs or replacements.
