In addition to flashing, a roof cricket can help divert water around your chimney so that it drains properly off your roof. It’s shaped like a double triangle and is installed behind the chimney so that falling water spills evenly down each side. This helps prevent water from accumulating behind your chimney, which can increase water damage and the risk of leaks. 

The International Building Code (IBC) requires cricket installation if a chimney built after 2012 measures over 30 inches in width. Chimneys constructed before that date are typically grandfathered in and aren’t required to have crickets installed.

A chimney requires both a cover and a cap, but these parts often get confused with one another. A chimney cover seals the top of the chimney around the flue pipe to prevent water from entering the chimney. A chimney cap is a piece that sits above the flue to prevent animals, debris, and water from entering the flue.

A hot fire alone will not remove significant creosote buildup and can be dangerous, as it risks causing a chimney fire. While the warmth from a fire can help loosen stuck tar, making treatments like creosote logs more effective, it is not a substitute for proper cleaning. For existing creosote, the safest and most effective method is to have your chimney professionally cleaned by a chimney sweep.

A spark arrestor is not the same as a chimney cap. Both sit on the top of the chimney. However, the cap keeps debris from entering the chimney, and the spark arrestor’s primary function is to prevent burning embers from escaping. Some spark arrestors are integrated into the chimney cap, and others are installed separately.
