I am trying to figure out what is going on with this house, hoping someone here can help me.
The house is block, single thickness, built in the 50s. The exterior is stucco, the interior is some kind of parging with no backer (applied directly to block). The windows were replaced about 3 years ago, but this problem predates the new windows because there's a lot of built up patch material in the problem areas.
Basically moisture is getting inside the block somehow. There are through and through cracks in the block, and the interior surface is bubbling. This is all happening fairly slowly. What I can't figure out is how the water is getting into the walls.
Below are some images of the roof, the roof edge directly above, the window corners, and the interior wall.
