Dear Dave, this is very common, especially if you are burning not fully dries wood, but solid fuel will do it in cold weather. It is condensation running down the inside of the chimney and running out of the gap between the roof fitting and chimney. The usual (partial) cure is to fit a double skinned chimney with the inner pipe slightly smaller in diameter than the actual stove pipe so the tar drips back into the stove. You may have to fill the void between the inner and outer lining with heat resistant spray foam. The removal of the stains is not easy and may damage the paintwork. I have tried a number of cleaning agents and a variety of "solvents" including some that are highly inflammable but I still had to compound & Tcut the last of the stains from the paint. Tony Brooks
