Old sealant and nails are removed, and a slot is cut in the mortar to allow the insertion of new flashing.
The first of two pieces of cricket flashing has been installed on the high side of the chimney. (The next photograph shows this same scene from the other side.)
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.
