What device is utilized with chimneys that do not penetrate at the roof peak, helping to shed water away from the chimney?

A cricket is a crucial device for chimneys that do not extend through the roof peak. Its primary function is to divert water away from the chimney, which helps prevent water from pooling around the base of the chimney and reduces the risk of leaks, which can lead to structural issues over time. The design of a cricket creates a sloped surface on either side of the chimney, effectively directing rainwater away, ensuring proper drainage away from the chimney structure. This is particularly important in areas where heavy rainfall is common, as it protects both the chimney and the roof.

In contrast, flashing serves to seal the joints between the chimney and the roof but does not actively divert water, nor is it effective for chimneys that do not penetrate at the peak. A corbel is a structural element that helps support the chimney but does not provide any function related to water drainage. Lastly, the term "chimney" itself refers to the entire structure rather than a specific device designed to manage water flow. Thus, choosing the cricket highlights its dedicated role in enhancing the longevity and integrity of chimney installations.
