Can’t find roof leak

[Krharvey44]

Good evening
I have a roof leak and I have sealed around vent and added a Perma boot. Any suggestions ?

Welcome.
Well, I would have like to have seen the area, prior to all the mastic having spread.

Were it I, I'd see if somebody sells those or similar 3 tab 235lb felt shingles, remove the shingles and roof-jack and repair and replace the roofing.

This is what it looks likes a few weeks ago after the initial patch I put on.

Thanks.
There is a you-tube video, "how to shingle around roof top flashings," that is descriptive of the proper method of addressing roof-jacks.
In my practice I've not used ABS roof-jacks, and have consistently used only FHA roof-jacks, also I've never left nails exposed. The roofing material in the video, while being asphalt, are known as architectural, while yours appear to be just 3 tab, so the nailing is a bit different.

It sounds like you've taken some good initial steps by sealing around the vent and adding a Perma Boot. If the leak persists, it could be coming from other areas such as damaged shingles, flashing, or even around chimney seals if you have one. I’d suggest checking the roof for any cracked or missing shingles, as well as inspecting the flashing around vents, skylights, and chimneys. If you’re unsure where the leak is coming from, you might want to use a garden hose to test different areas or consult a roofing professional to help pinpoint the exact problem.

I see a potential problem right away. See the red circled area. Blocking water courses is never good, allows water in but no easy way out. If you must, block it completely. This is pretty messy and should be fixed by a pro. I prefer lead stacks, j s.
