What term describes the supporting structure for a cricket in roofing?

The term that describes the supporting structure for a cricket in roofing is the wood frame. A cricket is a small, sloped structure designed to direct water away from roof features such as chimneys or walls, preventing water accumulation and potential leaks.

Wood is commonly used in the construction of crickets because it is strong and can be easily shaped to create the necessary slopes for proper drainage. The use of wood allows for custom sizing and adjustments based on the specific requirements of the roofing system. In contrast, options like metal frames, concrete blocks, or plastic composites are not typically utilized for this purpose due to factors such as weight, malleability, and difficulty in achieving the precise slopes needed for effective water diversion.

Thus, the wood frame is the most suitable and widely accepted choice for constructing a cricket in roofing applications.
