Chimney crown vs. chimney cap: what each one does
Chimney crowns and caps serve different purposes, both crucial to protecting your chimney from weather and debris.

What is a Chimney Crown?
A chimney crown is a concrete platform that covers the top of your chimney. It extends beyond the edges to keep out rainwater, preventing damage to the masonry and interior.
The crown is an essential component since it helps direct water away from the chimney structure. Cracks or damage in the crown can lead to leaks and further damage, so it's important to ensure it's in good condition.
What is a Chimney Cap?
A chimney cap sits atop the chimney opening, usually made of metal, and is designed to keep debris, animals, and moisture out. It's crucial for preventing rainwater from entering the flue.
Besides protecting from the elements, the cap helps prevent downdrafts from entering the home and can reduce odor issues by allowing smoke and gases to vent out properly.
Why Both are Important
While both serve to protect the chimney, they do so in different ways. The crown offers structural protection, while the cap provides immediate defense against elements and critters.
Ensuring that both the crown and cap are well-maintained is vital. They work together to extend the lifespan of your chimney and keep it functioning properly, reducing the need for costly repairs.
