Here in Seattle... just the last month we are approaching I believe were at something like 23 days striaght of rain... I believe 32 is the record! With the wind and the rain... it's hard at times to totally seal up your chimney.
I will be tackling this issue in the coming weekend. I believe I can get some tar and just "cake the heck" out of the area where the brick meets the deck of the roof... I think there is a layer of flashing up there to also work around. Roof is only 7 years old... it's just an issue on the one side of the chimney of course... where the wind and weather ususually come from....
I have heard that the best thing to do is use a "hot torch"... I guess you really get thru to the cracks and seal it up that way??? Were in the middle of winter however!
Any ideas on the best way to do this... much appreciated
