IIBEC Registered Roof Observers (RRO) Practice Test

Crickets should be installed on the high side of curbed openings to effectively guide water away from the curbed area and prevent water accumulation. A cricket, which is a small triangular or sloped structure, helps to divert rainwater towards drainage points and minimizes the risk of pooling water, which can lead to leaks or damage over time.

By positioning the cricket on the high side, it allows the water to flow over the cricket and towards the lower edge of the roof, enhancing drainage efficiency. This is especially important at curbed openings such as vent pipes, HVAC units, or other protrusions where water is more likely to gather. Proper placement is essential for maintaining the integrity of the roofing system and ensuring long-term performance.
