The one meter wall around the roof level was left uncovered block and I'm convinced part of the roof leaking problem was water seeping in through the block even though the block sits on top of the cement roof slab. I may be wrong but it definitely looks better, I'll be able to seal and paint it and will be able to run the impermeabilizante 20mm up the wall.
The other water issue is the windows. I like the steel frame windows but they don't seal well when rain water is blown against them. I took care of the side windows with plastic in a wood frame but the two front kitchen windows have water spouts above them. When the wind is blowing there's no way to keep that much water out. That's what the small awning or marquesina is for in the bottom picture. They'll start stuccoing it today.
