Chimney crown vs. chimney cap: what each one does
Understanding the roles of a chimney crown and cap can help homeowners maintain their chimneys in better condition and prevent costly repairs.
The Role of a Chimney Crown
A chimney crown is a concrete or mortar slab that covers the top of the chimney structure, preventing water from entering the masonry.
It should be properly sloped to direct water away from the chimney, protecting against weather damage that can lead to structural issues.
What a Chimney Cap Does
A chimney cap, typically made of metal, sits above the flue opening, keeping out rain, debris, and animals.
It also helps prevent downdrafts, where outside air is forced down the chimney, bringing unpleasant odors into the home.
Why You Need Both
Together, a chimney crown and cap work to protect your chimney from water, animals, and debris, helping to extend its lifespan.
Regularly inspect and maintain both components to ensure they are effective and not showing signs of wear or damage.
