Crickets or saddles shall be installed on the ridge side of any chimney greater than how many inches?

• A. 20 inches
• B. 25 inches
• C. 30 inches
• D. 40 inches

Answer: (C)

Crickets or saddles are used to direct water away from a chimney and prevent leaks where the roof meets the chimney. They create a small peaked channel that runs along the high side and helps water shed onto the roof planes rather than pooling at the base or against the flashing. When a chimney rises noticeably above the roof line, water tends to follow the high side and can back up toward the chimney, increasing the risk of infiltration. Placing the cricket on the ridge side gives water a clear path to run off the roof, reducing ponding and sending runoff away from the seam. Because this risk grows with height, the practice specifies installing crickets or saddles for chimneys that exceed that height, making this the correct approach for maintaining a watertight intersection.
