Vent pipe repair

The vent pipe repair in this shot looks questionable to me. Would you call this as an area to monitor and maintain or something you’d recommend a roofing contractor look at? This was a mock inspection, I’m just looking for some clarity/insight. Thanks in advance.

The lead boot was damaged (likely by a squirrel) so they slid a cut-off section from a new boot to cover the top.

Have a new vent flashing installed.
