I'm having aluminum wrapped on the fascia boards while the new gutters are
being put on.

Is the new wrap supposed to be "L" shaped, with the bottom edge just tacked
to the bottom of the existing fascia? Or, is it supposed to be "J" shaped
with a little bend along the back bottom edge so it wraps up behind the
existing fascia?

It is more work to tuck the wrap behind the fascia, especially with the
vinyl soffit j-channel right there. But it looks tacky otherwise.

thoughts?
