Chimney crown vs. chimney cap: what each one does
Learn the differences between a chimney crown and a chimney cap, and how each helps protect your chimney.
Chimney Crown
A chimney crown is a slab, usually made of concrete, that covers the top of your chimney. It slopes downward to direct water away from the flue and prevent moisture from seeping into masonry walls. A well-maintained crown can significantly reduce the risk of water damage.
Cracks or damage to the crown can lead to water penetration, damaging the chimney structure over time. Regular inspections and maintenance help ensure the crown continues to divert water efficiently and effectively.
Chimney Cap
A chimney cap sits above the crown, often with a mesh sides, and serves as a cover for the chimney flue. It prevents rain, snow, and debris from entering while also keeping out small animals. This helps maintain a clear flue and reduces weather-related damage.
Having a cap installed protects your chimney and home from various intrusions and blockages. It’s a relatively simple and cost-effective measure to enhance the longevity and safety of your chimney system.
Choosing the Right Protection
Both the chimney crown and cap play vital roles in protecting the chimney system, but they do so in different ways. An effective chimney system requires both components to be in good condition.
Ensuring both the crown and cap are installed and maintained properly can prevent many common chimney issues. Consult with a chimney professional to evaluate your current setup and make recommendations for improvements.
