Is this chimney flashing sealed properly?

[Sukhoi]

One of the roofers is coming back tomorrow to finish a couple feet of ridge shingles they were short, but didn't mention anything about doing more to the chimney flashing. Is this finished? Do I call them out if they just do ridge shingles and try to leave? It seems like it needs sealant all along the top edge. I don't understand in the current configuration what would stop tons of water from going behind the flashing.

Separately, other than being ugly, is the soldering functionally ok? It doesn't look too cold & brittle to me, but I have little experience on non-electronics.

Looks very well done to me. It needs a bead of polyurethane calking across the top and it's golden.

that looks fantastic. as greenman said, a bead of caulk along the groove will finish it off. my chimney flashing looks much worse and is functional.

I've seen far to many that have a piece of sheet metal stuck to the brick with a half gallon of snot.

my steps buckled because of heat expansion and poor install and pulled the nails holding them into the brick on the last house.

Thanks guys! Their workmanship has been pretty good on everything else, so hopefully the top will end up sealed today without me having to say anything.

UNEXPECTED UPDATE: They sealed it with mortar. Opinions? It's probably fine for now, but I'm worried about it cracking due to thermal expansion coefficient mismatch between the mortar and copper. Can't see it too well in the pic but they didn't mortar the vertical gap which worries me about water running down the brick sneaking in there.

I presume I should be prepared to put a tube of polyurethane on it in the future. If/when I do that, should I try to knock out some of the mortar first probably?

The flashing is suppose go further in, not tucked and folded back. The leading edge of the flashing at the brick will wick water into the seam. Then again, 99% of the new construction I have personally seen in Atlanta done in the past 25 years either did the flashing wrong, or NOT AT ALL. When I had to replace the bedroom windows above the den where the den's bay windows ceiling fell due to bad flashing, I had to lierally hunt for months to find a sub that knew what the F they were doing. In the end I did and the job was great. Flashed and counter-flashed properly. Hasn't leaked since.

Perfectly acceptable method of sealing the flashing. If your worried about it, have a look every few years and touch it up if necessary.
You have what appears to be a very professional installation. Pay your roofer, say thanks, refer him to your friends, and stop looking for flaws.

Heh I'm just sensitive to this because that top edge of flashing is the one place we've had a roof leak

The industry standard is a Z type flashing. That would be mortar joint ground out on top and the top of the Z inserted into the joint space and pointed in. Hard to tell if that was done. Looks pretty good tho
