What is the term for the area above the chimney that protects it from weather damage?

The area above the chimney that protects it from weather damage is referred to as the crown. The crown serves as a protective covering for the top of the chimney, preventing water from entering the flue and causing deterioration due to moisture. A well-built crown is typically sloped to direct water away from the chimney structure, which helps to prevent erosion and leaks over time.

By contrast, the flue is the internal passage that exhausts smoke and gases from the fireplace or stove to the outside atmosphere. The chase, on the other hand, refers to a structure that encloses the chimney, often extending from the roofline to the ground; it can include both the chimney and additional protective components. Lastly, a cap is a covering placed on top of a flue to prevent debris and animals from entering while also offering some protection from rain; however, it does not extend to the whole area above the chimney like the crown does. Therefore, the crown is specifically designed for weather protection, making it the correct term in this context.
