That’s why the residents of Boerne, New Braunfels, Seguin, Schertz, Spring Branch, Helotes, and the other surrounding areas of San Antonio trust in the Chimney Safety Institute of America (CSIA) certified chimney sweep technicians at Wolfman Chimney & Fireplace for all of their chimney system needs.
We often get questions from homeowners about the different components of their chimney system and why they are important. Most chimneys have the same six basic components: a flue liner, flashing, a smoke chamber, a damper, a chimney cap, and a chimney crown. Two of these components – the chimney crown and chimney cap – are close together and serve similar purposes, which leaves many wondering what the specific differences between the two are.
Let’s take a deeper look and explore the key differences between your home’s chimney crown and chimney cap – and why they’re both essential for the health of your chimney.
What Is a Chimney Crown?
A chimney crown is traditionally a concrete slab that sits at the top of your chimney, covering the entire top surface. It’s designed to protect the chimney from water damage, which can cause cracking and deterioration of the masonry. The crown is supposed to be sloped to direct water away from the flue, and it should have an overhang to keep water from running down the sides of the chimney too.
Chimney crowns are typically built during the construction of the chimney, but they can also be added later as a repair or improvement and can be metal.
What Is a Chimney Cap?
A chimney cap is a metal or masonry cover that sits on top of the chimney flue. It’s designed to keep rain, winds, and debris from falling down the flue and into your home. Chimney caps can also prevent animals from nesting in your chimney, which can cause blockages and fire hazards. Like chimney crowns, chimney caps are typically installed during the construction of the chimney, but they can also be added later as a repair or improvement.
What’s the Difference Between Chimney Crowns & Chimney Caps?
Now that we’ve defined both components, let’s dive into the key differences between a chimney crown and a chimney cap:
- Purpose: The main purpose of a chimney crown is to protect the chimney masonry sides from water damage, while the main purpose of a chimney cap is to keep water, debris, and animals out of the flue.
- Location: The chimney crown sits on top of the entire chimney structure, while the chimney cap sits above the flue covering the crown and flue liner.
- Material: Chimney crowns are typically made of concrete, while chimney caps are most often made of metal or copper.
- Installation: Chimney crowns are usually installed during the construction of the chimney, while chimney caps can be added later as a repair or improvement.
- Cost: Chimney crowns and caps vary in cost due to their size and the materials used.
Chimney Crown & Chimney Cap FAQs
Q: Do I need both a chimney crown and a chimney cap?
A: Yes, both components are important for the health and protection of your chimney. The crown protects the masonry from water damage, while the cap prevents water, debris, and animals from entering the flue.
Q: Can I install a chimney cap without a chimney crown?
A: While it’s technically possible to install a chimney cap without a crown, it’s not recommended. Without a crown, water can still seep into the chimney flue and cause damage. The crown is your chimney’s first line of defense against water entering your chimney system.
Q: How often should I have my chimney crown and cap inspected?
A: It’s recommended to have your chimney inspected annually by Wolfman’s CSIA certified chimney sweeps, who can check the condition of both the crown and cap and recommend repairs or replacement parts, as needed.
