A cricket/saddle is desired when a penetration is at least how wide?

A cricket or saddle is a structural feature built on sloped roofs to divert water away from a penetration, such as a chimney or vent, thereby preventing water pooling and potential leaks. The design of a cricket is particularly important for wider penetrations because as the width increases, the potential for water accumulation around the penetration also increases.

When the penetration is at least 30 inches wide, it is significant enough to warrant the use of a cricket to effectively channel water away. This size threshold takes into account the need for adequate water flow management and helps ensure that the roof remains watertight. By implementing a cricket at this width, it reduces the risk of water damage and extends the lifespan of the roofing materials surrounding the penetration. The emphasis on this size reflects standard industry practices for effective roofing and waterproofing techniques.
