Roof Cricket

Definition

A roof cricket is a relatively small elevated area of a wood roof constructed to divert water around a chimney, curb, or other projection.

Purpose

The purpose of a roof cricket is to prevent water accumulation and direct water flow away from roof penetrations, reducing the risk of leaks and water damage.

Examples of Use

• Roof crickets are installed behind chimneys to divert water around the structure and prevent pooling.
• HVAC units on roofs often have crickets to channel water away from the base of the equipment.
• Skylights and vents use roof crickets to ensure proper drainage and avoid water infiltration.

Related Terms

• Flashing: Thin material used to prevent water penetration at roof joints and projections.
• Saddle: Another term for a cricket, often used interchangeably.
• Drainage Slope: The angle at which a roof is pitched to facilitate water runoff.

Notes

Proper design and installation of roof crickets are essential to ensure effective water diversion and prevent potential roofing issues such as leaks and water damage.
