Cricket (roofing)
Appearance
A cricket is a ridge structure designed to divert water on a roof. Generally found on the high side of a chimney or the transition from one roof area to another, the cricket is normally the same pitch as the rest of the roof, but not always. Smaller crickets are covered with metal flashing, and larger ones can be covered with the same material as the rest of the roof.
Crickets are also often referred to as "saddles" in this context.
