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.

Regular professional chimney cleaning and a well-fitting chimney cap are two of the most effective measures to help prevent flue blockages. Annual cleaning keeps the flue from developing a thick layer of creosote. The chimney cap keeps debris out and stops critters from going down your flue for shelter while carrying clog-worthy nesting material.

Yes, it’s worth capping a chimney. Here are several reasons to install a chimney cap:

• Keep out rain, snow, wildlife, and other debris

• Help prevent chimney fires

• Reduce your chimney’s exposure to moisture

• Maintain your chimney flue liner

• Help reduce energy bills by helping regulate your home’s temperature

Most homeowners put a layer of compact sand or gravel at the bottom of their firepit, but you can also choose more decorative options like fire-resistant paving stones, bricks, or fire pit glass. Dirt by itself can even work, but other materials do a better job of spreading the heat around.
