What is a Chimney Cricket?

A chimney cricket is a small, triangular-shaped structure located on the back slope of a chimney. It is also sometimes referred to as a "chimney saddle" or a "chimney saddleback."

The primary purpose of a chimney cricket is to divert water that flows down the roof away from the chimney. Chimneys are particularly susceptible to water damage due to their protrusion from the roof and their exposure to the elements. Water can enter the chimney through cracks or holes in the masonry, causing structural damage and potentially leading to costly repairs.

A chimney cricket is designed to redirect the flow of water around the chimney, preventing water from pooling on the back slope and seeping into the chimney. The cricket is usually installed when the roof is being constructed or re-roofed, and it is typically made of the same material as the roof (such as asphalt shingles or metal).

In addition to protecting the chimney from water damage, a chimney cricket can also help to prevent ice dams from forming on the roof. An ice dam is a ridge of ice that forms along the edge of the roof, preventing melting snow from flowing off the roof and causing it to back up under the shingles. This can lead to leaks and water damage in the home. A chimney cricket helps to prevent ice dams by allowing the heat from the chimney to escape, melting any snow that may have accumulated on the back slope.

Overall, a chimney cricket is an important element in protecting the chimney and the roof from water damage. It is a simple and effective way to extend the life of these important components of a home.
