bendrulz, I agree with dupree, the goop on those joints is pretty sloppy.

Sometimes we re-point with mortar and sometimes we use sealant depending on the project.

I always like to use an NP1, geocel, or other commercial sealant: proper backer-rod, back-stop on the flashing, strike the joint flush, and a sand treatment on the surface so it blends with the masonry joints.

IMO a well-done sealant joint on counter flashing is better than re-pointing because unless you knurl the surface of the copper, the mortar can slide out...
