tmtorrijos,

I think you have made a good argument that things on the outside are not revealing much. So my suggestion would be to start looking inside. Clearly there must be moisture coming from somewhere. One of the other people on this post indicated that their problem was a leaky dryer vent. Let me tell you what I found and you may want to do some inside investigation if you haven't yet. My Bleeding only occurs in the winter. Here is why. I went up into my attic to do some investigation. I went to the wall where my bleeing is occuring. I pulled the insullation away from the sheating and found the brownish/redish stain on my top plate. After talking with some construnction friends I confirmed what I thought: Warm air from the living quarters is coming through the ceiling and condensing on the cold sheathing. It is penetrating the buffalo board/fiber board and running down the outside finding its way through a seem in the Tyveck and out onto the siding. My construction friends were somewhat suprised that this process woudld create the volume of bleeding that I am seeing. Well that isn't the end of the story. I worked my way to anther point along the wall and found perhaps the major source of my problem. I pull some insulation back and revealed a sewer vent line where somehow a 90 degree elbow had broken and basically my sewer vent was venting right into the insulation, right next to the sheathing (vent comes up through the outside wall). Don't ask me why they did it that way when they built the house but there you go. So basically this warm sewer vent was providing all kinds of moisture to my east wall. Lots of condensation, lots of bleeding. So I am going to address the sewer line and see what happens. Maybe you want to do some exploratory surgery in your attic and see if anything strange turns up.

I have the same issue with my siding. This started early this week. Temps outside have been in the 40's with no recent snow storms. I had a plumber come over today and he said this is not a plumbing problem. He suggested it may be a roof problem. Keep me posted on any answers to this problem. My brown leak looks similar to the photo that was posted. The liquid is initially watery but hardens and darkens with time.

Your siding is more than likely leaking,....There are many many ways your siding will leak. The browish stain left behind is from the tanic acid on wood your leak travels on before exiting in the least resistant spot.(most of the time) Paint under the butts can make it travel and show up in other spots, non level vinyl will let it travel as well.

Without details or photos it is hardest for anyone on the Net. to help you, The only fact you can get is that ...yes...your siding is leaking !! But you already know that,...so without being there to watertest or photos to examine signs, that`s pretty much all you`re gonna get. A small photo of the stain on two siding butts like provided earlier, is totally useless !!

Example: Help, my tire is flat and every time I put air in it, it goes back down, What`s the problem,...any advise will be helpful,..thank you !!........

The bleeding is mostly coming from below that window in the photo but there is an area that is also bleeding just above this window. The plumber said he thought it maybe a roofing problem. The only issue with that is we have had no snow here in a month. I guess it could be frozen gutters but not sure. I am having a roofer come over to take a look. If it is not the roof and not plumbing does anyone have an idea where else this liquid could be coming from?

Ok, It is hitting the top of that window and running down both sides. Does it show up inside at the top of the window ?

There are a few things that can cause leaks without rain or snow.

Check these,then get back to me,

1, Vent pipes that don`t have a downward slope (pitch) from the elbow that goes up to the roof back. Condensation will build up and go through joints.

2, Bathroom vents that don`t vent outside via flex hoses or hard lines.

3, If your heater and A/C is in the attick, there should be a drip pan with a pipe to drain out the house under it. This drain pipe should be pitched too. After it goes through the opening, it should stick out into the gutter or far enough so it don`t back track into the opening.

4, If you have attick insulation on the inside of the roof, improper ventilation will condense and run down the foil that is on the other side of the paper backing and down the wall on both sides.

5, Are the roofing nails that come through the wood rusty ?

Let me know what the roofer says, and see if he will do a water test with a garden hose. Gutter first, then the roofing from the bottom up.

The roofers came out and said this is not a roof problem. The most likely cause is condensation behind the siding. I am being told that there is probably a void in the insulation. When the cold air outside is meting the void in the insulation from the warm house, condensation is formed. I am in the process of trying to find a company with an infrared camera. Using the camera will give me an idea of where the void is located. Once the void is located I will be able to have insulation pumped into that area. Hopefully this will correct the problem. As always I am open for suggestions.

Answers to oddballs questions:

-I don't have a humidifier

-A/C is not in the attic

-The leaking is not showing up inside anywhere including that window. It seems to now only be running down under both sides of that window.

-It is a pretty new house so I believe that the bathroom vents are all being vented correctly

-I don't believe that the roofing nails are rusty.

By the info you just gave me, I strongly suggest you have the top of that window tested with a hose. I don`t see any drippings comming out of the sillplate onto the foundation concrete at the bottom. I can`t see the water getting through the house wrap underlayment to the back of the siding either.

In any case, let me know what`s discovered !!

Would this whole thing start when we have not received any moisture if it were the window? I guess that is the thing that it puzzling me the most, this started when we had not received any rain, snow, moisture at all in over a month. How do I go about testing the window with the hose? Thanks!

Now there you go,...throw a wrench in the mix !!

No, I don`t think leak now. Maybe a bee hive, I seen that happen before, exterminator kills the bees, the hive leaks later, it`s just that it`s too much for condensation that I`ve seen happen. Ya never know till you start taking siding off and that`s the last step.

Let the hose trickel on one corner and see if it comes out the other side. But I`m shying away from that now.

It`s not a big deal to remove the siding, just have the correct paint for after. Keep me posted, I`m interested !!

So I finally found the cause of my leaking siding and it was of course the most obvious cause, the upstairs shower. Water has a weird way of traveling especially when it can follow studs and come out in an area that does not seem to be obvious.

I found the source by hiring a guy that uses infrared technology. He used an infrared camera to detect the moisture and found that the source of the moisture was right under the upstairs bathroom window. The window is inside my upstairs shower (thank for that great idea by the builder)

For anyone having this problem, mysterious leaking siding, I would recommend finding someone in your area that uses infrared---it was under $200.00 and worth the price so I did not have to start ripping everything up to find the cause.

I have the same problem and am just as stumped. To the person who asked about the humidifier the problem seems to have stopped since I turned down the humidifier. Could this have been the cause? Have Roofers and insurance adjusters baffled.

Update . . . my humidifier on my furnace was set to 35%. When the weather turned very cold I saw quite a bit on condensation on the window as well as the bleeding on the siding. Since I turned down/off the humidifier and cleaned the siding I have had to more bleeding. Keeping my fingers crossed.

Hmm, I'm not sure what that could be. We had problems with our gutters that ended up causing drips inside of our house, but not on the siding

Check out this photo, this doesn't happen every time it freezes but will happen after a few weeks of freezing to warming weather.

I just turned my humidifier down now. We have gone from -35 C to +2 in a 48 hr period and our siding is dripping on all four sides of the house. Also notice the coke like stains in several places. I hope the humidifier setting solves this problem so I can move on to the ice damming on the garage roof. That will be another post once I exhaust a few options. Any advice would be great... An don't say move ( I know minus 35 is cold :) )

We have a similar problem with the siding on our house. I've recently added insulation to our attic, along with ventilation chutes down into the soffit area between each rafter. Since then I've occasionally noticed water dripping down the siding. It appears to be coming from behind the siding, but I can't seem to pinpoint the cause. I see this on all four sides of our house, even on the gable sides of the house (so it probably isn't from ice dams). Any help is appreciated--thanks much!

I have a two story home in Lakewood CO. The attached picture shows the 2nd floor outside the bathroom. I'll admit this bathroom was used as a steam room and is not equipped for that.
This appears to be bleeding or and not dripping or dirt etc condensed onto the outside of the wall.
The better part is that it is water soluble which has me scratching my head. The drips and bleed easily wash off.
