Last November I had the roof stripped and shingled and the chimney re-built
above the roofline and the guy that did it said I should get up there and
waterproof the chimney in the spring when it's warmer. Well it's spring and
I want to do it but I was wondering what I should use? I have used
Thompson's in the past(mixed results) but was wondering if that is the best
stuff to use. What do the Pro's use? Thanks for any help.....
