What is a Chimney Crown?
A chimney crown is a slab, usually made of concrete, that covers the top of your chimney. It functions as a roof, preventing water from seeping into the brickwork and causing damage. A properly constructed crown will slope away from the liner to direct water off and away from the chimney.
Cracks in the chimney crown can allow water to penetrate, potentially leading to leaks inside your home. Regular inspections can help catch these issues early, preventing more costly repairs down the road.
Purpose of a Chimney Cap
A chimney cap sits above the crown and includes a metal covering that prevents rain, snow, and debris from entering the flue. It often features a mesh siding that keeps birds and small animals from nesting in your chimney.
The cap also helps prevent downdrafts that can bring cold air and soot smells into your home. Chimney caps are essential for protecting the interior of the chimney from weather and wildlife-related damage.
Working Together
Both the chimney crown and the chimney cap play vital roles in protecting your chimney. The crown protects the chimney structure from water damage, while the cap prevents the interior flue from external elements.
Ensuring both the crown and cap are in good condition is crucial for avoiding water damage, blockages, and animal infestations. Regular checks can help maintain these components, extending the life of your chimney.
