Chimney crown vs. chimney cap: what each one does
Chimney crowns and caps play crucial roles in protecting your chimney. Understand the difference between these two important components.
What is a Chimney Crown?
A chimney crown is a slab, usually made of concrete, that covers the top of the chimney. Its main function is to protect the chimney structure from weather elements like rain and snow.
The crown slopes slightly to direct water away from the chimney, preventing moisture from seeping into the masonry. Regular inspections ensure that cracks or wear on the crown are identified and repaired promptly to prevent damage.
What is a Chimney Cap?
A chimney cap sits above the chimney crown and serves multiple purposes, such as preventing rain, snow, and debris from entering the chimney. It also functions as a barrier against animals looking to nest inside the flue.
A chimney cap includes a mesh screen that allows smoke to exit while keeping unwanted visitors out. This not only prolongs the life of the chimney but also ensures proper airflow, which is crucial for efficient and safe fire burning.
Maintenance for Crowns and Caps
Both the chimney crown and cap require regular maintenance to function correctly. Cracks in the chimney crown should be repaired immediately to prevent water from leaking into the chimney, potentially causing damage.
Chimney caps should be checked and cleaned regularly to ensure that the mesh screen is not clogged with creosote, which can be a fire hazard. Hiring a professional for periodic inspections can help keep these components in good shape.
