Bob, inspectors are supposed to write in cryptic sentences. If Jim understood what you are talking about, you must be doing something wrong!
By the way - I agree with Jim.

I did a lot of building with cedar. The brown staining is probably tannin acid. It is what gives Cedar its rot resistance. It is not unuasal to have this staining on lighter colored stains. Moisture migrating out from the back side of the claboards will make this normal condition worse. This as you surmized is what you are seeing on this house.

Check the lumber stamp (S-GRN? Surfaced 'green', i.e., not kiln-dried). Also check other things that could pump moisture up to the attic (water penetration into basements, perimeter drains that are open at perimeter, high water table, humidifiers, a lot of shower use, dryer exhaust terminus). Sounds like tannins leaching out. How about the paint...was it peeling off?

The stuff I see isn't from tannins. While I see it on old cedar siding, I also see it on old fir siding.
And lately, I'm seeing exactly the same stuff on Hardiplank. I think it has more to do with asphalt from the tar in the felt paper.
Here are some pics from a house I inspected in mid February. The house is six years old.
This stuff ain't tannin.

What else can you tell us about that place with the stains and Hardiplank? Weird.. Moisture issue indoors? Were you able to get at the gable ends (if any)?

Jim,
Is the use of tar or felt paper predominant in new construction in your area? Around here we get tyvek house wraps and our staining (normally through vinyl) results from improper fasteners being used on the wrap...

I have had some trouble with Protecto Wrap. This is a rubber based self sticking product that comes in rolls in 6" to 12" widths. It is real similiar to Ice and Water Shield but a heavier product. We would use this as a sealant over the flanges of the windows. I found that on a hot summer day that the product would break down and leak out a black substance.

Maybe not predominant, but many of the builders are returning to it after bad experiences with Tyvek. Felt is cheaper, faster, more forgiving and, in the end, seems to work better. Did I say it was cheaper? - Jim Katen, Oregon
Then we'll see its return here shortly, I'd imagine...

Ok so I see he post is old but hope to get a response. So I have the same stuff on the side of my house. My house was just built in September and the North side has 3 "runs" down the side that look just like it (thanks for the pics). I am not sure what building code is (have to look) but it appears the bathroom exhaust fan isn't piped outside just into the attic so I agree it is some sort of condesation going to the outside. My question now is what is the proper fix?

Have them install a rain cap with a male extension through the roof and connect the bath fan to the rain cap with an insulated connector; not an uninsulated foil or plastic connector. Don't allow them to leave any dips in the connector that will collect water and eventually overflow and flow back.
Make sure whoever does it knows how to keep the roof singles in proper drainage plane around the rain cap. If the word 'caulk' comes out of his mouth, get someone else - those can be installed completely caulk free and never leak.

I have a house built in 1983 with Seletex? sheeting and masonite horizontal siding. As soon as it gets cold outside, i also get that brown liquid coming out from the siding. it is the worst around the two bathrooms. To go with this, I have noticed the bottom 3 or 4 siding planks to have rusty nails, and you can see the siding bowing a bit higher up on the wall. The colder it gets (42 in the attic this morning) the higher the humidity which was 65%. No roof leaks, bathrooms vented, i put in a new ridge vent and increased the size of the soffit vents to increase flow. there are no water pipes or anything in the attic.. I will say that the house is constructed as follows: drywall, then sheet plastic, then the insulation &framing, seletex, and siding. I have already spent a ton of cash trying to figure this. also replaced all of the insulation in the attic as well. Al of the contractors around here give me a different answer...Oh yeah, the interior house humidity is never higher than 40-45% if that helps.

Are you on a crawlspace? What other construction specifics?

My bet would be on the plastic sheeting. It is holding the moisture in the wall cavity. The Celotex substrate if it is the one I recall acts as a moisture barrier so whatever moisture is caught in the wall cavity will remain. I know that in many parts of North America the plastic sheeting is used but only in much colder areas of the country. Whenever I find plastic sheeting behind the drywall in the areas I inspect I almost always find moisture problems associated with it.

ok, so short of tearing down all the walls is there a fix? I had a guy use a moisture meter, and it was dry in the drywall, and on both sides of the plastic sheeting.. the inside of the Celotec was dry but as he pushed it through towards the outside.. the meter pegged bout half way through celotex. so it's weird that the inside walls are dry, but the moisture seems to be between the celotec and the siding.. The hunidity in the house is great and never overly high. I have 2 little boys, so its the mold that worries me.

Moisture is not the only thing that can influence a moisture meter. There's some skill involved in interpreting the readings.
Am I correct in assuming that this brown liquid been coming out for almost 30 years?

unsure.. we bought the house 4 years ago. it was freshly painted. didn't notice this till after we a really bad winter back in 2010. it seems very daunting of a job and really expensive to fix.. got a quote for redoing all of the siding and rewrapping house for about 40k.. no way i can do that..

Hi,
What kind of Celotex is used behind the siding - foil-faced foam or Blue Ridge fiberboard? The Blue Ridge fiberboard is made from post consumer waste and is bonded with a vegetable starch material.
It sounds like extractive bleeding. Moisture-laden air from the interior is diffusing outward. It reaches the celotex and cools to dew point. When enough accumulates, it drips down the wall behind the siding and extracts color from the sheathing or any asphalt-based felt water resistant barrier between the sheathing and the siding.

blue ridge fiberboard i believe.. Wouldn't the plastic vapor barrier prevent the moisture inside from permeating through though? And again the inside humidity levels are fine. Woke up this morning my attic temp was 44 with 69% humidity?? dry as a bone outside, I think its all a related issue, but have no clue even where to start.
