We would love some help with a slightly different situation. The chimney and house were built 1955. The water seeps in at the ceiling line. It is always hard to say exactly where a leak is coming from because the water migrates. They replaced the roof, rebuilt the cricket, and replaced the flashing six months ago.The leak has slowed, but not stopped and is coming from the same place. The bricks appear to be porous. In the past, when they have been treated with silicone, the leak has stopped for a year at a time. They brought in some high-end roof consultants in the early 90's who said the basic problem was the use of substandard bricks which are porous.
Any ideas about what to do? Thanks!
