Roof leaking by Chimney, No Flashing
I have an older home that I am restoring. I am not a roofing expert but the roof has a leak right at the chimney and it ruined a large section of drywall. I removed the drywall and sealed all of the gaps that I found but still have a leak at the top. When I looked up top I noticed there is no flashing around the chimney. I was told it is too much trouble to install flashing on the chimney right now and to wait until I get the roof replaced. What is the best way to seal this? Also my roof is good for at least 4-5 more years. Any info would be appreciated. Thanks.

It is not too hard to install a proper chimney flashing, but a little care must be used to install the step flashings also called baby tins if they are not currently there.

It is about a 2-4 hour job on the roof, depending on the pitch and how many sides the structure has, plus the time to fabricate the flashings at their shop prior to installing them.

Don't let anyone convince you that plastic roofing cement will work long time, unless you enjoy replacing wet and damaged drywall and wet insulation in the attic.

I agree...flashing can do wonders to save your house from water infiltration. Here's a story that gives a good overview of how it's installed. A little technical if you're not doing it yourself, but it helps to know what the contractor is talking about!
