To ensure proper functioning of your fireplace's chimney, it is advisable to opt for an annual inspection and cleaning, as recommended by the Chimney Safety Institute of America (CSIA). This will help identify any blockages or damages that could potentially lead to overheating or fire hazards.

Alternatively, if you prefer a DIY approach, you can purchase a sweeping brush and seal your fireplace tightly with plastic to capture all the soot during cleaning. However, the process of removing the chimney cap and inspecting the chimney liner for tears, as well as checking for any obstructions in the shaft, requires climbing onto the roof and should be performed with caution, using protective gear such as a respirator, safety goggles, and gloves.

It is worth noting that some individuals may prefer to hire professional chimney cleaning services rather than attempting the task themselves.
