Inspected a 1986 stained cedar siding home today. Unusual moisture intrusion, patches and discoloration in the attic that I recommended the client get looked at further by a remodeler/framer. As I’m writing the report and reviewing the photos it became apparent (maybe) that something else was missing. Shouldn’t there be sheathing and a moisture barrier visible on the outside attic walls? Photos 2,3,4 are all of the inside of the wood siding. Are exterior planks directly on the studs an acceptable method? I realize this is Framing 101 but I just don’t ever remember seeing this particular arrangement, help me out here .
