When a roof slopes down to a chimney, there can be problems from the force of the rain water running down the roof and hitting the chimney. The water can run up the chimney and get under the flashing or back up under the roof shingles causing a leak. A fix for this problem is to install a cricket (or a saddle) to divert the water off the chimney. We have installed several and have had good success in stopping leaks that could not be fixed with flashing or caulking. You can see how the cricket works by looking at the picture of the completed installation. Water is diverted away from the chimney and down the sides.
