remove the nails at the perimeter of the flashing,and from upper 2-3 shingles using a "flat" bar,install a caulk bead 1" in from the perimeter of the new flashiong(on the bottom of it-karnak ultra)install a new ventpipe flashing and reinstall the same shingles,install spots of caulk where the tar lines were disturbed

Go to a roofing suppky shop and buy a proper lead stack flashing. Then do as TRG described above. Assuming this is a plumbing pipe that the lead can be folded into. If not make sure when youg et the new rubber gasket it has a metal base. They are much more stable than the all rubber boots which usually don't last more than a year or three.

We replace ALOT on the tract homes built by the production builders. Quantity over quality? Bad idea. That's why we use the lead when ever possible.

If you do install the Lead Plumbing boot, make sure that you only trim off the excess lead to a point that goes at least 1" to 1 1/2" above the top of the actual pipe.

Then either use the handle of your roofing hatchet or hammer or a rubber mallet and Gently tap the Lead into the inner circumferance of the pipe, until it folds neatly, without any tears, into the pipe.
