I have read the other threads about chimney leaks. they don't seem to address my problem.

I have a 40 year old house. I have the orginal roof. the flashing around the chimney seems to be inset in the brick. I have added sealer to the flashing. I have also resealed the shingles to the flashing. I am still get leaks in a hard rain. The water seems to flow down the outside of the brick and come down exterior of the chimney into tliving room.

I am open to suggestions.
