Chimney crown vs. chimney cap: what each one does
Understand the roles of chimney crowns and caps to protect against water damage and animal entry.
What is a Chimney Crown?
A chimney crown is the uppermost layer of your chimney and acts as a barrier to protect against water damage. Made from concrete or metal, it covers the chimney top, sloping slightly to divert water away from the flue.
It's vital to keep the crown in good condition because cracks or damage can lead to water seepage, causing further damage to your chimney and even impacting the interior of your home.
Purpose of a Chimney Cap
A chimney cap is a metal cover placed over the top of the chimney. It protects against rain entering the flue, blocks downdrafts, and keeps animals and debris out.
By preventing water and animal entry, a cap helps maintain the internal condition of your chimney, making it a critical component for chimney longevity and safety.
Why Both Are Important
Both the chimney crown and cap play different roles in protecting your chimney but work together to ensure comprehensive protection. While the crown provides a broader shield against the elements, the cap offers targeted defense at the flue level.
Regular inspections can help maintain both components. Making sure they are intact and functional will save you from potentially costly repairs and ensure your chimney system works efficiently.
