A chimney constructed like this could ALWAYS be sided. Masonry absorbs water and passes it into the attic. Brick or stone used on a chase will all the time leak and needs to be eliminated and changed with siding to cease the leak.

Subsequent you’ll transfer down the roof to the realm marked zone #2. That is the realm of the roof approx. three toes above the flashing, and the realm on the chimney approx. one foot above the flashing. Saturate this space closely. Working slowly from left to proper. If the chimney has brick or stone on it’s exterior you need to moist it till the masonry is saturated. Once more, give it 10-Quarter-hour of heavy watering earlier than transferring on. Mark any leaks within the attic or ceiling earlier than transferring on.
