I have water damage on an inside corner where wall & ceiling meet with crown molding. The crown molding is all bubbled and directly on the other side of this wall is a chimney. The chimney flashing on the roof looks good and the outside bricks near to that area need repointing. Could this be allowing water in? Or could it be something to do with the bricks right next to the wall? or a chimney liner? The chimney is no longer being used. Several masons have looked at it but no one can seem to figure it out. Any ideas?
Thanks in advance!
Hi Anne
A few factors can be at play here. First and very often , you must be very sure about the flashing around the chimney. Upon very close inspection, you must insure that all the caulking is in good condition and check to see if any screws have lifted. Very often snow builds up around a chimney and as it melts water can find it's way threw small fishers and cracks in the mortar
and brick. If there is a cement cap on top of your chimney, there could be a crack in that as well. If this is no longer being used. Have it removed down to your roof line.
This may have nothing to do with the chimney at all. Don't be fooled by the point / location of visual damage.
Likely an ice damming issue this time of year....water will follow the path of least resistance. Entry could be 20ft over & exit at the point of damage. Needs to be traced back to the point of origin...often difficult.
Hi Anne,
Yes, I agree with Derek. Your leak could be somewhere else on the roof. Ice damming can cause water to back up under the shingles. The only way to see for sure is to go up into your attic and see if there are water marks on any roof framing ( rafters ).Water will ride on the rafters until it reaches a vertical member and then go down and make it's way through onto your ceiling.
