What is a Chimney Crown?
A chimney crown is the top surface of your chimney, typically made of cement or metal. It functions as a protective layer that prevents water from entering the masonry, which could cause damage over time.
The crown slopes downwards to direct water away from the chimney structure and is crucial for prolonging the lifespan of your chimney by preventing moisture infiltration.
Purpose of a Chimney Cap
A chimney cap sits above the chimney crown and serves to prevent rain, snow, and debris from entering the flue. It also acts as a barrier against birds and small animals that might try to nest inside your chimney.
Equipped with a mesh screen, the chimney cap also helps in minimizing sparks from exiting the chimney, adding an extra layer of safety for your home.
Maintaining Your Chimney Cap and Crown
Regular inspections are key to maintaining both the chimney crown and cap. Cracks in the crown should be promptly repaired to prevent further damage to the chimney structure.
Ensure the chimney cap is securely attached and free of rust and wear. Regular cleaning will keep the mesh screen clear of debris, ensuring proper ventilation and function.
