a pipe going to the roof is dripping water now.

It is raining heavily outside, and I found out a pipe that seems to go up to the roof is dripping water around its fitting area, see the red circle area in the attached photo.

I have two questions,

a:What is this pipe for? What it is going up to the roof?

b:It seems that I can reach the leaking area relatively easy, can I simply do some quick fix around the fitting area or that is something I should leave to a professional?

Thanks!

It's a vent pipe, and the leak needs to be fixed on the roof, not on the inside. The rubber on your roof boot flashing has degraded. You can caulk it temporarily but the boot and probably some of the shingles around it will need to be replaced.

One hack, if you want to call it that is to take the rubber from a new boot and simply slip it over the old one, and caulk between the two. Then it can be fixed properly the next time you need a new roof.

There might be a 1% chance that the fitting you have circled wasn't glued but that's not as likely as the roof boot leaking.

Sorry for the possible dumb question, to me it seems the water is coming from the fitting area of the pipe, not the roof(the roof looks perfectly dry)

The roof is only about 3 years old, we did have a major hailstorm about 6 months ago though.

When the rubber boot leaks, water follows the pvc pipe down and drips off the fitting. You would need to get up there and look. I'm not psychic, so I can't tell if it's dripping from the joint or if water is running down above that joint and just dripping off it.

You can see purple glue at the red arrow.
Nothing seen at the blue arrow.

I googled a little bit, it does not look too difficulty for the repair itself, but climbing up and working on the roof top sounds a little bit scary. I will call the roofing company tomorrow and see if this is under their warranty as the roof is only 3 years old.

Yeah, i just climbed up and took a close look, the leak is not from the fitting area, it is coming down from the roof.

The flashing is leaking and may have been damaged by hail. The typical roof flashing with the rubber stretchable seal is notorious for short life, but usually will last 10 years unless damaged. I have found that Oatey makes a great rain collar to seal these leaks up that just slips down over the vent pipe and slides down to cover the stretchable seal that has failed. You can't tell from the picture, but they are made from a thick rubber that lasts for years and keeps a repair from consisting of replacing the entire flashing.

The next best alternative is to replace the cheapy flashing with a lead flashing.
