What happens if a chimney does not have a proper cricket?

When a chimney does not have a proper cricket, increased moisture retention is a significant concern. A cricket, which is a small sloped roof structure installed behind a chimney, helps divert water away from the chimney’s base. Without it, water can accumulate around the base of the chimney instead of being directed away, leading to moisture retention in the surrounding areas.

Excess moisture can result in several issues, such as damage to the roof structure, the potential for leaks into the attic or living space, and deterioration of the chimney itself over time. The lack of a cricket can create stagnant water pools that promote rot and mold growth, which can compromise the overall integrity of the roofing system and the structure of the chimney. This moisture-related damage can be costly to repair and can lead to severe structural problems if not addressed.

In summary, the absence of a proper cricket leads to increased moisture retention, which poses risks to the building’s integrity and longevity.
