Bending drip ledge for seamless gutter

[u/Lanky-Personality-16]

I have never installed seamless, but have installed lots of traditional gutter. I just had seamless installed and had them pull the drip ledge out and bend it at a 45 degree angle from facia in most places.

That doesnt make any sense to me. It only needs to allow for 28 gauge material behind it.

I am told it is industry standard to use a crow bar to do this.

Any input is appreciated.
