house is 9 years old. (as far as I know, no history of roof leaking)
This is in houston.
It rains fairly often in houston- no probelm for me
Three weeks ago- it rained for about 24 hours... and a few days later noticed a brownish patch on two locations on ceiling. I went upstairs and saw that the leak locations corresponded to the drain vent areas.
-the flashing looks intact
- the rubber collar around it looks intact. There is however a 2-3mm gap at two locations between pipe and collar (in essence I can see daylight).
- the blown insulation below the pipe looks intact (no sign of lots of water falling on it) but if you move the insulation you can see the water stain on the ceiling board.
I figured water will come through the leak in very small quantities everytime it rains. However with many hours of rain the water is significant enough to dampen the ceiling.
-Will putting some roof/flashing sealant solve my problem?
- should I put from the inside or outside of the roof?

YOUR DIAGNOIS IS THE BEST I HAVE SEEN YET, BLESS YOU. THE RUBBER THAT SEALS THE PIPE IS PART OF A NEOPRENE VENT PIPE ROOF JACK. THE SIMPLE FIX IS TO CAULK WITH SILICONE OR SOME OTHER FORM OF SEALANT. U CAN REPLACE IS THE SECOND CHOICE WITH THE SAME PRODUCT AND IT WILL LAST 5-? ;YEARS. U CAN USE A LEAD ROOF JACK BUT IF U HAVE A SQUIRREL PROBLEM THEY WILL CHEW THE LEAD UP. THE PERMANET FIX IS TO USE A METAL ROOF JACK WHEN U GET A NEW ROOF.

You are correct that the water is leaking in very small quantities, but at least you now know that it can happen. Reflashing the vent properly and sealing it is the only way to correct the problem once and for all. This would all be done from the outside.
Since water leaked into your attic, be sure to throw away the insulation over the leak. Mold will start to grow within as little as 24 hours given the right conditions. After that, you can use stain-blocking primer on your ceiling below.
In Illinois, we have to disclose any flooding or leaking when we sell the house and also have to disclose if/when/how the problem was fixed. You may have a similar law in Texas and the more time that passes since your repair, the better it will look when you move.

Put a bead of black silicone between the rubber collar flashing and the pipe. They must have damaged the collar when they installed it or they may have purchased a bad one. Black or clear silicone all the way around. Stick the tip of the caulking gun in the rubber collar at the very top. Pull the trigger and move the gun around the lip. When the collar seats to the pipe, you should have enough caulk squeeze out and seal the areas that are leaking.

You should go out and buy you a tube of "tar" or " roofing caulk" and place a thick bead around your plastic flashing or your lead flashing. The tube I am talking about is over with the roofing materials at your local Homedepot or Lowes. Good luck.
