Ridge Beam/ Stucco crumbling away
I just noticed today that it looks like the roof ridge beam is pushing down on the stucco causing it to "bubble" out a bit and at one point a decent chunk of stucco has come loose and I can see the inner wood. I can fix the stucco but what is causing this. The house is close to 90 years old and on the other side of the roof it is fine but I can see there was some patch work on the stucco done in the same area but it looks fin. Any ideas or suggestions?
