    My vent stack boots are in very bad shape and the rain must have been combing into the attic. The pipe was 3", so I bought a 3" to 4" rubber adaptor from Lowes and put it down, I think it should work. Anybody else try this? The alternative is to remove the boot (and plate) from shingles and replace.

    I have a 2" vent stack also. This one doesn't look to be leaking yet. I don't think there is a 2" to 3" adaptor readily available, so I'm looking for ideas.

    I don't know the various sizes available. Just adding my 2 cents that mine leaked (they dry rotted and leaked when it rained) and I bought a replacement boot, slid it down over the existing one, cemented it in place. Was an easy fix. I used a lot of tar (from a caulk gun type of tube). You are on the right track.

    I was just researching products for roof project and came across a pipe collar at: www.wilmarproducts.com. It just sides down. I am not sure if will fit over a no-caulk Oatey type flashing. It seems like it is just a flared adapter as opposed to the DWV reducer (which should work anyway).

    Yes, mine dry rotted. A replacement boot would be just the thing. Where did you find it?

    Steam man, thanks for the link, but it doesn't look like it'd fit.

    That will work. Personally, I'd take the old one off and install a new one. The pipe collars come in a few sizes.
    Rule of thumb, one covers several sizes. Use the one that rated for that size or smaller. Never use one that made for a larger size than the pipe your flashing.
    Muck works, but does crack over time, makes a mess, and if you need to take it off, good luck. Its a PITA.
    Top 1/2 of collar at very least should be under the shingles. the bottom 1/2 or few inches on top of shingles. Exactly where depends on where the shingle courses are.
