Hi. I have a 1950's ranch house on very expansive soil. Ground movement throughout the year causes hairline cracks in the stucco on the south side of my garage. I have patched the cracks with latex crack filler several times to no avail. The problem is being the south side on the house the summer sun beating on the walls over the years has cooked the tar out of the tar paper backing. Now when it rains you can see water coming through and soaking into the studs. Is there any recourse other than tearing off the stucco and replacing the paper?
