Chimney crown vs. chimney cap: what each one does
While both chimney crowns and caps are important, they serve different purposes in protecting your chimney.
Chimney Crown
The chimney crown is a slab that covers the top of the chimney, extending past the edge to protect the masonry from weather damage. It’s typically made of concrete or metal.
Its job is to direct rainwater away from the flue and chimney structure, preventing water damage and extending the life of the chimney.
Chimney Cap
A chimney cap sits atop the chimney crown and includes a protective mesh. It is designed to keep rain, debris, and animals out of the flue, enhancing the safety and effectiveness of the chimney.
In addition to these protective roles, a chimney cap helps prevent downdrafts and sparks from escaping, making it an essential safety feature for your home.
Maintenance and Inspection
Both the chimney crown and cap require regular maintenance. Inspections should check for cracks in the crown and examine the cap for wear or damage that might compromise its function.
Prompt repair of these elements can prevent costly damage to the chimney and home, ensuring efficient chimney operation and home safety.
