You are all good with that

A bituminous product is less preferred to a butyl product for the volatility factor but the fiberglass is very inert.

Both should work fine but butyl is supposedly better.

Thank you both! So it's okay that they used a roofing product? I guess I didn't specify that, but that's what it is. Roofing ice guard.

Should be okay.

Bit more old school but if done properly, it should work.

Ok thanks! I'll look into the "if it's done properly" part! :-)

+1. Butyl is preferred, but the bituminous should do fine. I wouldn't use the granulated generic stuff, but something like grace will work fine.

Homesealed, by granulated do you mean the surface looks like coarse sandpaper? If so, that's what they are using. Would that be worth changing? They might need to reinstall the doors anyway due to improperly flashing them.

The corners Will be the week spot, a flexible panning tape would be better or at least more fool proof. Did they taper the sill? How did they address the corners?

In my experience that stuff doesnt stick very well.
My only additional comment would be to be aware of the fact that there is a difference between using IDEAL materials and procedures, and those that are IMPROPER. It sounds like your guys are making an effort to meet your expectations in this case which is a very positive sign.

I do appreciate the difference but also commend you for pointing it out: it keeps the GW reputation up. There are plenty of forums with an alarmist attitude. I did want to be sure that using an asphalt containing product wouldn't void the door warranty as I believe it will for the window warranty (at least they make a point of saying not to use them). The door instructions didn't specify as the windows did.
However, IF it turns out they need to reinstall due to improper flashing on the rest of the unit, would it be wise of me to request a different panning material (at my cost) while the doors are out?

Rigid pans are ideal but trickier to work with.

I would stay with HomeSealed's advice in that they are making every effort to do it properly and the systems that they are using have worked for decade.

Heck...guys would flash with 15lb felt and could make a window tight as a drum.

Much of the product development that has come out is designed to help cover up poor workmanship and allow for track builders to slap up stuff that won't leak.
