you are correct Will. now for terminology purposes are we calling it head flashing per Jim’s reference.
In the photo I posted, there is missing both the drip cap and the head flashing.
The drip cap should have been installed over the window, tucked under the housewrap, then the head flashing (which would be the tape) would cover it up.
All the best buddy.
Look at my previous post:-)
I will call them out every time.
What you said 
I called out the fact they did not properly cut the openings on the housewrap.
They cut all around the opening instead of making an upside-down “Y” and then folding the sides back over the studs.
I asked them to provide me with the documentation they used to support the way the did it, after I provided them the housewrap manufacturer’s installation manual. I’m still waiting…
Just a suggestion Will.
The world of trades is hard. I was there to long and the bad social habits I picked up are hard to shake off.
That being said; they do come in useful when working within the over sight field.
They all want to know how to do it right except the cost cutter. Head office. the boss. If you have to pay the men that extra to make it right. Tell them to call you any time for anything buddy. You will make some long lasting friends IMO.
When its all over and they packed their bags to leave;
Give’em s h i t BOY!!! and scream like a banshee. HA HA HA . Make them feel at home…
You get more flies with honey than with vinegar.
