What is the purpose of a cricket in roofing?

The primary function of a cricket in roofing is to enhance drainage around roof penetrations. A cricket is a sloped section of roofing that is built on the uphill side of a chimney, vent pipe, or other roof feature; its design encourages the flow of water away from these potential leak points. By directing water away, crickets help prevent the accumulation of water which can lead to leaks, water damage, or other roofing issues.

This focus on improving drainage is especially crucial in flat or low-slope roofs, where standing water can be more problematic. Crickets ensure that water is diverted effectively, minimizing the risk of pooling and providing a safeguard against weather-related damage.
