A cricket or saddle shall be installed on the ridge side of any chimney or penetration greater than 30 inches 762 mm.

A cricket or saddle is a ridge structure designed to divert water on a roof around 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.
