 shingles at the starter edge

No one here extends the starter or shingles over the edge by any more than maybe an 1/8th of an inch if at all. Usually the end right at the edge of the drip edge. In fact I have seen other inspectors report negatvely about doing so, why I have no idea.

Construction has an amazing number of regional practices; might be there was some legendary roofer that started all this years ago, and it just spread.
Charlie Woods had a little statistical game he'd play regarding the same thing in HI work; one guy says something, two people hear it and each tell two more, etc.
Pretty soon, you have a lot of HI folks doing something really stupid, and no one's sure where it came from, but everyone's certain it's right.
As far as this roof, I can imagine a few possible problems with what you've got there. I'd also be curious if there was IWS under everything; N. Dakota gets the ice dams, as you know from last winter.

In my areas the starter strip and shingles hang over a half inch or more. My understanding is to let the water drip off the shingles into the gutter or on to the ground.
Over an inch is too much. This could let the wind blow the shingle up. IMHO

Have a good day inspecting.

Don't they have drip edge up there? All I see in the pic is rake edge. The ice won't even have to reach the shingles before that mess leaks.

My concern with that installation off the top of my head is as to whether the head lap is adequate. If that starter was designed/ cut so that there was just enough overlap, then there is now not enough overlap. There would then be a potential to have water leak in at butt joints (every 39" or so).
If a proper dripedge flashing is installed, the lap is adequate, and everything is detailed properly below the visible shingles, you will probably be OK. The only concern I can think of is that if the shingles are cut flush with flashing, water could wick up the flashing, especially on a lower sloped roof.

Yes the starter strip is to be extended over, the edge, for years there were no metal drip edges installed, and lots of those roofs lasted the expected life.
It would not surprise me to find out that this is a retro fix, done by picking up the tabs and sliding the shingle under to get the over hang that was not done when the shingles were installed, probably only extends up a hair past the tab cut out.
