The peak on the upper side of the chimney is covered with WinterGuard, flashing and then roofing tiles. Note that only flashing from the far side was installed at the time of this picture. Additional flashing was installed after this picture was taken.
Custom-cut, single-piece counter flashing provides a cleaner look with fewer seams.
Stepped counter flashing is set into slits in the mortar and sealed. It lays outside of the base step flashing to ensure that no water can enter the house between the chimney and roof.
