I am trying to figure out the cause and remedy to an exterior water staining condition and wanted to seek the expert-generalist advice of the forum. This water stain picture comes from my brother, who lives a few hours away in Austin. It is located on a western facing garage eave. There doesn’t appear to be any wood rot yet and based on what he said there was no water staining on the interior attic/ceiling area. Any thoughts and/or recommendations are greatly appreciated as it will be a while before I can get down there for a visit.
