Chimney crown vs. chimney cap: what each one does
Both chimney crowns and chimney caps play important roles in protecting your chimney, but they serve different purposes.
2 min read
Understanding the Chimney Crown
The chimney crown is a slab of concrete, stone, or metal that covers the top of your chimney. Its purpose is to prevent water from seeping into the masonry, which can cause damage over time.
A properly constructed chimney crown will have a slight slope to direct water away from the chimney. Regular inspections can help ensure there are no cracks or deterioration that might compromise its effectiveness.
The Role of a Chimney Cap
A chimney cap is a protective covering that sits on top of the chimney crown. It typically features a metal hood with mesh sides, designed to keep rain, debris, and small animals out of the chimney.
Chimney caps are crucial for preventing downdrafts, which can bring smoke and odors back into your home. They also help to reduce moisture accumulation, which can damage the chimney structure.
How They Work Together
While the chimney crown and cap have distinct functions, they work together to protect your chimney from the elements and prevent damage. Maintaining both is key to ensuring the longevity of your chimney.
Ensure your chimney professional checks the condition of both the crown and the cap during regular inspections. They can recommend repairs or replacements if needed to keep your home safe and dry.
