Chimney crown vs. chimney cap: what each one does
Chimney crowns and caps play different roles in protecting your chimney from damage.
Understanding the Chimney Crown
The chimney crown is the top portion made of concrete or mortar that covers the chimney, sloping to shed water away from the flue.
It prevents water from entering the chimney structure, avoiding damage to the bricks and mortar. Regular inspection can catch cracks early.
Role of the Chimney Cap
A chimney cap sits atop the flue, preventing rain, debris, and animals from entering. Many caps have mesh to reduce downdrafts.
Installing a chimney cap improves safety and efficiency by keeping unwanted elements out of the chimney.
Maintaining Both Features
Routine maintenance of both the chimney crown and cap is crucial to prevent water damage and extend the chimney's lifespan.
Checking and repairing these components ensures proper function and protects the overall structure of the chimney.
