TL;DR
Cricket flashing is the metal covering shaped over the small peaked diverter built behind a chimney or other wide roof penetration, splitting descending water and snow around the obstruction. Fabricated from galvanized steel, aluminum, or copper and woven into the step flashing and underlayment, it eliminates the dead-water zone where debris piles and leaks begin.
What it means
Cricket flashing is the metal covering shaped over the small peaked diverter built behind a chimney or other wide roof penetration, splitting descending water and snow around the obstruction. Fabricated from galvanized steel, aluminum, or copper and woven into the step flashing and underlayment, it eliminates the dead-water zone where debris piles and leaks begin. Roofers either clad a framed saddle or bend a self-supporting unit for narrow chimneys; on reroofs, a missing one behind a wide chimney is a deficiency worth correcting while the deck is open.
