chimney removal question

I removed a leaky, unused brick chimney from a 1 story ranch.

I only brought it below the roof line and removed the bricks and clay liner up to the point it comes thru the attic floor. I then covered the top with sheet metal affixed with construction adhesive and covered it with insulation.

Is there any point to have removed it completely all the way to the basement?

I see no need to demolish it any further. HOWEVER, it must be disabled completely by sealing up the entrance points below. If it is a fireplace, it should be closed up. If it is a thimble used for former water heater exhaust, it should be solidly occluded. You don't want the chance of another occupant to start a fire or exhaust anything not knowing the chimney isn't functional.

I typically only remove chimneys to get them below the roof. Sheet over the hole and shingle. I don't even bother taking it below the floor level of the attic as it's just more work. I would only remove it down to the basement if you want to make use of the space somehow.
