The (exterior) walls of my place are of stucco.

The garage does not have an interior wall and I’ve noticed that when it’s a heavy rain, the wood slats become damp. What I need to know is that if the stucco is good, why should moisture creep onto the boards and dampen it? Is not stucco a type of concrete?

My concern is if this phonomenon is happening elsewhere to the house. :-(

The house is 60 years of age and I have to wonder how many years a stucco is good for before it needs to be replaced. I’ve noticed a few house in my are have recently been stuccoed.

Stucco is not generally waterproof in itself. Cement stucco is porous and will allow moisture through. There has to be a moisture barrier between the stucco and the framing. In the old days this was generally done with a layer of asphalt impregnated felt paper or roofing felt. The problem is the roofing felt can become dried out and deteriorate from contact with the cement based stucco. For that reason many installers today are using a double layer of roofing felt when installing cement based stucco. Using this method, should the first layer be in direct contact with the stucco and deteriorate the second layer, that is protected from contact with the stucco, will maintain the moisture barrier.

It is very possible the problem exists in numerous areas of your house. I suggest you hire a certified home inspector to come out and check the moisture content in the walls to determine the extent of the problem and any possible damage.
