Chimney Flashing
The number one area of a leak in a home is where the chimney meets the roof deck. When we find a problem in this area we take everything off the roof deck and around the chimney until we find the leak. We cover the roof deck and part of the sides of the chimney with Ice and water shield, which is a 3 foot roll of waterproofing material.
The counter flashing goes over the top of the step flashing and is tapped into the brick after making a small cut in the brick and sealed. 
If necessary we will install a cricket on the chimney to keep water moving to the sides of the chimney. This gives a triple layer of waterproofing for a 100% watertight seal.
