What is the primary reason creosote must be removed from chimney systems?

Creosote is a highly flammable substance that can accumulate in chimney systems as a byproduct of burning wood and other fuels. The primary reason for its removal is to prevent chimney fires, which can occur when creosote ignites due to the high temperatures generated during the combustion process. If left unchecked, the buildup of creosote can reach dangerous levels, significantly increasing the risk of a chimney fire that could potentially spread to other areas of the home, causing severe damage or even loss of life.

While improving aesthetics, preventing blockages, and enhancing airflow are also important considerations in chimney maintenance, they are secondary to the critical safety concern of preventing chimney fires. Regular cleaning and inspection of the chimney help mitigate this risk by ensuring that creosote levels are kept under control and that the chimney remains safe for use.
