Roof Leak around vent pipe opening

I noticed a stain on the upstairs ceiling. This weekend I mustered up the energy to get up into the attic. When I got to the spot where I figured the stain was on the ceiling below, it appeared that water had come in through a roof opening for a 1 1/4" PVC vent pipe. I got as close to the vent pipe as I could (Since there's no floor, one can only hang onto the rafters.) and noticed some light coming in around the vent pipe. How can I repair this? Can I just squirt some urethane foam up around the vent pipe?

Thanks

Interestingly, someone else had the same question about 10 days ago. Here is the thread.

You wouldn't just use foam because it isn't very waterproof, and the best repair cannot be done from the inside. Silicone or urethane caulking might be applied from the inside, but even this would only be a temporary solution until you can get on the outside. It's likely you need a new roof boot flashing.

they sell just the rubber boots fit different sized pipes, 1", 1" 1/4, etc that will just slide down the pipe.. pretty easy fix.. ive used lexel before on a hole in a roof and its still going strong 5 years later :P.
