I am writing after visiting your website. I have a problem with my 60 year old stucco home in Minnesota. I have two dormers stuccoed. They leak into the attic space. Each dormer leaks in front of the window. I had a roof replaced recently and the roofer has attempted to seal and reflash around the dormers. We performed a water test and it appears that the stucco is porous enough that water is getting through and leaking into the attic. Is this crazy?

You may check over the dormer to make sure you have

If you think everything is fine you can paint the stucco
with a masonry paint that will seal it up, but you lose the
natural color and will have to scrape and repaint
Hope this helps.
