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.

You should never block both the top and bottom of your chimney. Proper airflow is essential because the temperature inside the chimney will still fluctuate as your house warms and cools. Moisture can build up without ventilation, leading to dampness in your walls over time. Blocking the top prevents debris and animals from entering, but the chimney still needs air circulation to avoid condensation issues. Allowing the chimney to breathe maintains the health of your home and prevents long-term damage.

In some cases, you can use a fireplace once the insert has been removed. However, before burning a fire, you must have a professional inspect it and the chimney to make sure they're functioning properly and no damage has occurred from removing the insert. That’s because using a fireplace without an insert could create fire hazards due to issues with airflow and heat dispersion, depending on the fireplace design and material. A professional can advise on whether you should make certain repairs or modifications before using your fireplace as an open hearth.

Fireplace inserts have several potential disadvantages. The cost of the insert and its installation can be a significant investment, as the process can be complicated and expensive, particularly if modifications to the existing fireplace are necessary. Aesthetically, some people find that inserts lack the traditional look and authentic ambiance of an open, crackling fire. There are also ongoing costs for maintenance, cleaning, and fuel. Fuel type can be a limitation; for example, an insert may be unusable if you don't have access to its specific fuel source. Maintenance and repairs can also require specialized services, especially for gas or electric models. Finally, while an insert is more efficient than an open fireplace, it may not heat a home as evenly as a central HVAC system.
