Can anyone identify the name and manufacture of this underlayment?

Looks kind of like ice shield.

It's much thinner typical WSU, and it's distinguishing characteristic is that sort of "hem", apparently intended to attach to the fascia, likely its self-adhesive.

Still don't know what it is though...

What kind of roof is on top of it, that sometimes helps with identifying the underlay. Is it asphaltic or rubberized. The only way to know for sure is find a stamp or tape on it somewhere. Reporting it as an Ice Shield would be accurate..
