@Ricod - I want to say 6" but I'll have to climb up and confirm that.
The concrete is still curing downstairs so I can't get at it from the
base yet. It's definitely black plastic (pvc?) as I could see the
interior when they were cutting pieces and it was black all the way
through.

Black has always been ABS, PVC is white or cream colored.

If adding above the roof line be careful not to compress the rubber boot.
