Brown liquid dripping from soffit

Brown liquid dripping from soffit DEFAULT



West Central Alberta Coldest, wettest edge

My wife is upset, the North, and East sides of our house ( acutally, manufactured home, aka, a trailer, circa 1996) has ugly brown stains running down the vinyl siding.  This seems like as good a place as any to ask, someone here knows something about everything it seems.  

There is evidently too much moisture behind the siding, it must be picking up the dark color of the tar paper, then comes out the weep holes in the vinyl siding.  Mostly the top piece of siding, none on the south or west facing sides, worst on north, and some on East end, partly shaded.  Worst in winter time.  Roof vents are all clear of snow, no whirlybird thingy.  shingles in fair shape, no signs of roof leaking on the inside.  Bathroom vents go all the way through to the roof, attic/crawl space is not accesible to check without a sledge hammer and an even unhappier wife( hole in ceiling, dust everywhere.....)    We have extremely low humidity, especially this time of year, I have the cracks in my fingers to prove it, we do get wild temperature swings this time of year, 30 to 40 degrees C difference in 24 hours is not unusual.  No humidifier in the house.

What  else should I be looking for?  I don't think it is enough moisture to be fatal, but visually, it is a mess, and I've heard some saying about a happy wife, happy family, so I guess I'd better at least pretend to be doing something about it.




West Central Alberta Coldest, wettest edgeBruce, the soffit is clear, the house has almost no eaves, so the soffit consists of 2" of window screen stapled on. There is a huge ice dam on the North side, I've always thought that shingles were water proof, but I guess if there is standing water, they would have to leak. It seemed like it was going to break shingles to get the dam off, so it is mostly still there.

I took a couple of top pieces of siding off today while it was warm. I think I found where the brown color is coming from. thousands(millions?) of decomposing fly carcasses. An extremely pleasant discovery I might add. Could it be that the moisture is in normal quantity, but the staining is coming entirely from the flys? The tar paper is dry, and doesn't show any signs of water damage, snow is melting, and water running full bore today, and no sign of leaking.

How much do you know about your roof’s soffit and fascia? Today we will go over some key problems to keep an eye out for!

Stains

 Soffit And Fascia

Are Your Soffit And Fascia In Good Condition?

Stains that are brown will indicate a leak from your roof that has begun to affect your soffit. Your roof’s tar will create the brownish stains. If you notice black or green stains, these are generally caused by mold and algae, and should also be removed ASAP.

Moisture Damage

Spending years as a mount for the rain gutters can leave fascia exposed to water deterioration. This happens most commonly when your rain gutters start to overflow onto the fascia, instead of directing the water elsewhere. If your home doesn’t have gutters at all, your soffit and fascia are at a particularly high risk for moisture damages.

Leaking Gutters

Leaking gutter systems create the high chance that your soffit needs changing or service. Your soffit can take the damage as water cascades from holes or cracks, or stops up due to clogs. While its presence saves against the encroachment of this water into your roofing, the damage your soffit absorbs will increase over time.

Peeling Paint

As your soffit or fascia age, the paint may begin to peel. Peeling paint leaves your soffit and fascia vulnerable to damages from water, sunlight, and pests as well. It is also pretty unsightly. Be sure to have the paint refreshed swiftly.

Warping

If your soffit is consistently damp, it will begin to warp and buckle. Often this kind of damage is created by malfunctioning gutter, but it can also be caused by a roof leak. The warping can eventually make the soffit fall of completely.

A leaking soffit can be very worrying.  Why is my soffit leaking?

The most likely reason your soffit is leaking is from ice dams.  This happens when snow melts on your roof because the attic is too hot, and as the water runs down the roof it refreezes, forcing the ice up underneath the shingles and underlayment.  As this continues to happen water will drip into the attic and come out of the soffit.  Another reason the soffit could be leaking is not a proper offset of the starter strip, allowing water to travel up behind the roof and behind the fascia board.

Ice Dams

The most common reason for a soffit to be leaking is because of ice dams.  Ice dams are one of the most damaging things that can happen to a building.  It occurs during winter when there is snow on a roof.  If the attic is too warm some of the heat will make its way through the roof and melt the bottom layer of snow.  This water will run down under the snow until it refreezes either because it is touching too much snow, the house cools down, or it makes its way to the overhang where there is not enough heat from the house, this last reason is most common.  As the water refreezes into ice, it can push underneath the shingles and underlayment, and sometimes even make its way into the attic space.  Once here it can thaw again, and run down as water into the soffit, which is where the homeowner may see water leaking from.

One thing to look for to see if your house suffers with ice dams is icicles.  A byproduct of the water running under the snow and refreezing is usually very long and large icicles.  Their size will be a good indicator of how bad the issue is.  These ice dams can cause major problems.  They can drip through the soffit in their early stages, but they can also leak into the house through the ceiling.  They will slowly tear apart the roof and compromise its integrity and ability to shed water.  They can also lead to large amounts of snow suddenly falling from the roof which endangers the gutter, not to mention anybody unlucky enough to be under the roof when that occurs.

There are two things to do to solve the issue.  First of all, better insulation.  The entire issue is that the attic space is too warm, so insulating the floor of the attic can be a good solution.  Not that often the issue can be where lights are coming into the attic above, as they can be a major thermal bridge.  The next step is providing better air circulation in the attic.  You want to let your roof breathe.  Ensure there are vents in your soffit (if there are not, that alone may be the issue).  If there are vents make sure they are not blocked up, or consider enlarging.  Good air circulation can solve the entire problem.

Issues With The Gutter

Another reason the soffit may be leaking is that water is backtracking, or never reaching the gutter.  If the details at the edge of the roof are not done well, water could make its way to a multitude of places.  If the roofing material (shingles, a metal roof, etc.) is not properly feeding water into the gutter then water may simply follow the curve of the roof, and work its way back to the edge of the soffit.  Here you would most likely be seeing water dripping from the outside edge of the soffit.

There is a solution to the above issue.  Firstly, a gutter apron.  A gutter apron is similar to flashing, but it simply covers the space between the edge of the roof and the gutter, leaving water no choice but to enter the gutter.  Secondly, a large piece of drip-edge flashing.  Your roof should already have drip edge flashing to help protect the fascia board (doesn’t always work very well), but a large piece of drip edge flashing would both help to protect the fascia board and lead water into the gutter like a gutter apron.

Another very simple thing to check is if the gutter is clogged.  If the gutter is clogged, water may simply be overflowing and running off the inside edge of the gutter, and appearing to drop from the soffit.  If this is the issue, the fix is inexpensive and not difficult.  Just grab a ladder and throw on some gloves, then scrape out the gutter.

Other Possible Issues

There are a number of other possible issues as for why a soffit may be leaking.  If the fascia board is too high, higher than the decking on the roof, then when the drip edge is installed it can create a flat spot.  This is actually a fairly common issue, and can cause water to pool and slowly lead into the house.  The fix is to either lower the fascia board, to cut off the top of the fascia board, or to insert something raising the decking slightly.

Another issue is the starter strip is not properly offset, it can create a seam in the roofing.  Any opening in the roofing can be fatal, and water can work its way upwards by means of capillary action.  The fix here is probably to either find a way to seal the roofing, possibly by means of a silicon sealant, or to have a roofer weave the first few rows back into place.

What can I do about a leaky soffit?

Soffit seepage?

i don’t mean to be nit picky (but we all should), oil is “atomicly” lighter than water. that’s why in an oil spill the oil floats. not sure if that affects your theory, but thought i’d mention it.

You’re not being nitpicky, just uninformed. There are many different types of crude oil, the most popular being lightweight crude because it is so versatile in what can be made from it. Yes, lightweight crude floats. Heavy crude does not because it has more gunk in it.

Also keep in mind that oil-based paints are just that, “oil-based.” That means that there is much more in them than oil, and it is that “oil base” that separates from the paint and creates a gooey, syrupy gunk.

Also remember that in a bathroom, you have steam, which definitely is lighter than all oils. Steam rises. Since there is no where to go while you’re taking a shower or bath with that inefficient or non-working exhaust fan, it will force itself into the paint, forcing the “oil base” out, thereby creating that syrupy gunk.

At least that’s what Peter Gaeta of Gaeta Painting tells me. He says don’t put oil-based paints in bathrooms because it’s not a question of “if” you’ll get syrupy gunk, it’s a question of when.

Soffit dripping brown liquid from

Anybody Know what these brown "line" stains are on my vinyl siding???

Anybody Know what these brown "line" stains are on my vinyl siding???


HI Guys!

Looking for some help. These weird streaks appeared last year, and now they are getting a bit more pronounced (please look at pic). I have no idea what it is,it doesnt seem to look like the artillery fungus issues i've seen, and its way high up so I cant see if it washes off or not or tell the texture (i.e. sticky, whatever). First, the facts:

City: Toronto
Location of issue: Only the north side of the house - No other siding is displaying the problem. House backs and sides onto ravine (north side of the house that sides on the ravine is displaying the problem).

Now the detail, although it looks like dripping, I believe it is actually crawling "upwards", perhaps from the siding drain holes (?). This starting last year and initially I thought it was a burn mark from some kids maybe firing a firecracker at the house but then noticed the weird pattern. I can't check for moisture issues on the inside of the house, because the other side of the wall is our great room that has no attic, but displays no signs of moisture inside the house. Soffit looks clear, it looks like the underside of siding is getting darker quicker as well. Its about 30 feet up on an angled ground so its pretty treacherous trying to get up there with a ladder by myself......but i may have to!!!

Has anybody seen this before and know what is causing it?? I guess I have to pay a pro to replace or clean it because its real hard to get to but I'd sure love to know if there is anything I can do my self to fix this and spare the expense. Particularly if there is any concern from a health persepctive (i.e. mold). House was built in 1996, no other issues, great builder. Bug infestation between the tyvek and the siding????

Help! Thanks to all.

What type of sidding is it ?

What style of home is it ?

I,ve seen a few instances, from birds, bugs and bees to sweating and leaks !! Keep in mind sidding is meant to shead water and not water proof. Water developeing behind or carried behind, picks up particles, and stains will occur where it drains. Underlaymeant should be water resistant and allowed to breath.

We have cedar clapboard and our home is a 2 story colonial. We have had 2 roofers out and both agreed the roof seems intact. If the water source is from an interior pipe - water or drainage - wouldn't we also see water damage inside? How do insects/bees create water damage or bleeding?

OK, Colonial two story, clabboards, leaks on first floor only, good clues. step by step I`ll eliminate possibilities. Clabboards lap 1" 3/4 minus exposier. If you have additions with roof lines diagonnally down the plane, the first piece of stepflashing MUST drain on to the face of the last cut siding that starts up the run. A good way to tell is that you should be able to see the bottom of the first stepflashing. If you see the stepflashing drain behind the siding, the paint under the butts will keep it from draining out and still, if the lap is below the first stepflashing all the water will drain behind all the siding and the Tyvex paper or underlayment will keep it from showing up inside for years,but it will travel and show up on joints and weaknesses in the paint as drips that appear as bleeding. Also check the foundation to see green growth indicating draining from behind siding. If the siding is cut too close to the roofline you will get the same results as above.

If you have no lower rooflines, disreguard this reply and I`ll move on to another possibility. A photo of the entire side of the house would help alot.

I actually found this site because I was looking for some information about what I call my "Amityville Horror House" (because it's bleeding)! We also have a 2 story colonial, built in 1979. We have Hardiplank siding. I don't think it was ever stained, always painted. A year and a half ago, we had liquid siding put on the house. Now, there is a section on the second floor (we've seen it a couple of other places, but it's most concentrated in one area) that has reddish brown liquid lines running down, from under the siding. It's actually quite a lot! We suspect that freezing temperatures at night with warmer days aren't helping since we're seeing some of the siding start to bulge outward. On the interior of the home at that point is a closet, though there is a bathroom nearby. We've had some folks come look at it and they have suggested that the gutters need to be cleaned. Well, that was a simple solution, but the problem persists despite our clean gutters. We've checked the attic, but no signs of moisture leaking in there.

Sounds like a very similar problem - my husband and I have joked that we should just call a priest for an exorcism. We have cut holes in the ceiling thinking it was a plumbing problem, however, all pipes/drainage seem intact. We think it is a siding problem. Will post pic within a day or two. We have wet insulation as well as ice blocks seen from interior against exterior walls. Please keep in touch.

After many months we finally solved the mystery! Our laundry room is located on the 2nd floor and our dryer vent hose/pipe disinegrated inside the ceiling. Since I am constantly doing laundry, it was "spewing" moisture everyday into the walls and ceilings which in turn exited through the siding. We rerouted the venting through the attic and out and problem solved. Hope this will help someone else.

Hello,

I just noticed that my siding was bleeding all over the house and the siding has also warped quite a bit in a few places leaving some gap in the siding! We are really concerned why this is happening? Any answer would be much appreciated. Image attached.

What type of siding is it ? Either way, warping is almost always due to fastening (not enough) and that leads to improper insallation wich causes all kinds of issues. I cannot find the image attached !! Let`s start with the type of siding and how it`s terminated.

Okay, so here we are three years later, and things are no different. We've had people come and take off the siding in that area, just to see if there was any moisture behind the siding. Things were bone dry! The only thing we wonder is this: when we had the house painted a few years ago, several pieces of siding had to be replaced. Could this mysterious brownish bleeding be from having used incorrect nails? Could the nails used to attach siding be rusting? That's the color we're seeing. Neither of us remember whether or not siding had to be replaced in that area of the house or not. We're just brainstorming!

Streaking is almost always a leak. The color of the streak can tell you that the water is traveling through or over wood sheething/frame. redish brown is one of those colors. Photos` Taken from close and afar say alot

So I have read with interest the "bleeding" from the siding. I too have the brownish/Red bleeding going on (East side of the house). I had Hardiplank put on in Spring of 2008. I had significant water damage from leaky windows and so had to replace sheathing and new siding (along with a new pella window). Then last winter (Feb-Mar 2009), I had my first Bleed in one spot. Then just this week (Jan 2010), it finally got above 25 degrees and the bleeding began but in several spots and with a significant volume. I haven't confirmed that it is just on the east side but I haven't seen it anywhere else. I don't have a mosture issue that I can detect. What is the latest on this mystery?

You would be surprised how ice can get behind your facsia and accumulate behind the siding. When melting happens it begins to run out the butts. The streaks are what`s left when it dries out after. This happens with all types of siding. The tanic acid from the wood is the stain, even with vinyl, if it hits wood first.

Most of the time it is due to roofing flashing or gutters that have weaknesses under ice dams,while rain wont back up. Clogged gutters can do this in the summer too.

Hello,

Thanks OddBall for your reply.

I am not sure about the type of the siding.

I have attached a picture to this post. Please let me know if you can view it this time.

There is a lot of warping as well along with the "bleeding". The builder is Richmond American.

Just wanted to comment that you picture shows the same thing I am seeing. I would guess from your picture that you have hardiplank as well but I will yield to those more experienced. Do you happen to have buffalo board/fiber board used for sheathing?? My guess in my case that somehow my buffalo board is getting moisture and the brownish/reddish color is coming from that. Would OSB give the same color?? My problem has only occurred coming out of a cold situation and we just had some nasty snows with whispy like snow that may have gotten undernead the hardiplank and somehow passed moisture through the tyvek and then melted when it warmed up. can you tell I am guessing??

I'm glad someone finally posted a picture of this because it's exactly what I see. The problem now is this. . . I've had roofers come out and assess. They've found nothing wrong. We also keep our gutters clean, since that was one of our first guesses. Are we doing any sort of long-term damage to our home by just leaving it or should we try something else? The bleeding happens on the back of the house, so we are really the only people who see it. It's only a problem in the winter.

News flash, "After a cold flash", "only happens in winter" are better clues than that photo will give.

C`mon,..show me a little more than that !!

A well cleaned and maintained gutter full of ice will allow ..Back Up of ice under dripedge flashing at the bottom (eves) of the roof, it will also allow ice or melting to get behind the gutter if it does not have caulking over the back of it. Both of these senerios` allow the water to get to the back of the fascia, from there to the soffit, from there down behind the siding. Because everything is frozen, gaps and vents or spaces in the soffit are bypassed by ice bridge. If no soffit, even easier.

What I see, is run-out of a leak or damming problem, I`ve seen enough stains on clabboards to know. However, this is a first assesment of intel provided, and not me being there.

I started with the most common cause from the gutters. There are others, especially if you have dormers or vallies, skylights ect. ect. A wider photo of the wall is needed so I can see the contributors !!

We're happy to "fix the damage", but no one can tell us what is damaged. As I've mentioned before, the professionals who have come out can't seem to find anything wrong, so we're stumped. The first roofer who came out suggested that we put exhaust fans in our bathrooms, which we've done with no success. We do have one other professional in mind who hasn't seen it in person (although he has heard about it), and we're going to call him next week.

I appreciate all your help oddball. I'll be sure to keep everyone posted. I do feel a little better just knowing that other people have the same problem.

tmtorrijos,

Your problem only happens in the winter durring melting, Right ?

It`s almost always Ice damming getting behind the gutter or under the roofing. Sometime dormer flashing.

To give you better advice, I need a photo of the wall from a few feet back so I can see the entire wall plus gutter/roof, and a photo from the top of the gutter showing inside down the long way so I can see the top of the gutter and roofline. The signs will tell me the rest.

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.

-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.

Thanks for all the insights. I am confident my issue was poor ventilation from bath shower. Clapboards are fine, so how would you recommend I clean it off?

My mysterious drippings turned out to be from flashing that was diverting roof runoff directly behind my siding. This was not obvious from observation. The water would seep out from behind the siding at odd locations along the wall. The liquid was brown and thick. When we took the siding down, the plywood underneath was rotten in a small area, but luckily no internal damage.

Bleeding down the siding it's mostly caused by two things one is the wrong nails were used for siding anytime you do Cedar clapboards you should be using stainless steel nails 4 years any kind you could imagine Hardie board cedarcraft Cedar Shakes Azek vinyl you name it second reason felt paper behind the siding what's an old school way of doing vapor barriers and a lot of times people still use it and if it gets hot enough and moisture adheres to it in the evening times than it could bleed Leslie there's one very rare reason and that could be if you just had new shingles put on your house there's a chemical that is very hot areas will bleed off of the roof but eventually will go away bleeding off the roof and hitting your siding that's probably the least likely the other two reasons are the most likely problem

Heres mine please help. What could possible the cause if this, our roof just got replaced 3 months ago. Im just worried they might have messed up somewhere up the roof. And pls help me how to effectively remove the stain.

I'm having the same issue, a small spot on the east side of my house is weeping, but only in the morning. It stops by early afternoon. There are no pipes in this outside wall and none near it. It hasn't rained for weeks and it is pleasantly warm not humid. The roof is in good shape. The siding is cedar planks which are likely 50 years old.

Ok, guys. I need your help! Our home has Hardiplank siding. We have just noticed wet streaks or blobs coming from the bottom of our window on the exterior wall outside our master bath. There is no plumbing right at the window. There is a bathtub beneath the window, but there is no way the leak could be coming from that as high up as it is. Bath is on the second story. Picture is below. Any advice is appreciated.

We just had our roof and siding replaced last summer. In the fall, we started to see the same dark drip lines. Never had this before, so it has something to do with the replacement. Contractor is coming out in the spring once it warms up, but everyone is stumped on what is causing it.

I'm getting a random drip on the front of my house, condensation, attic HVAC or a leak? Doesn't happen consistently so I don't know what's causing it.

Have the same thing going on. Happens sporadically. We have just come out of an extremely cold spell and this is the west end of my house.

Q&A – Siding Stains: Why Do Houses Cry?

I recently had a reader email this question, and thought it would make for a good blog post:

We get brown water stains on our siding over the winter, but they mostly go away over the summer. Will you perform an inspection for those stains only (not a whole-house inspection)?

Stains on siding

While we’re happy to conduct single-item inspections to troubleshoot problems exactly like this, this particular situation is so common that it probably doesn’t need an inspection.  The stains on the siding are the result of moisture; that much is for certain.  When water runs through the wood and wall sheathing, it picks up tannins in the wood and leaves dark stains on the siding.  If the home experiences ice dams and the stains start at the soffits and run down the siding, they’re probably the result of water leaking through the roof as a result of the ice dams.  The illustration below from The Ice Dam Company shows the path of the water.

Anatomy of an ice dam

Here’s an extreme example of what you might see on the side of the wall during the winter:

Ice on wall

Here’s a close-up photo showing some ice turned brown from the tannins in the wood:

Brown Icicles

Here are a couple of photos showing what stained siding looks like after all the ice is gone.

Stains on siding below soffit

Stains on siding below fascia

Gable WallSo ice dams are one possibility.  In this particular case, I got a little more information from the homeowner and decided the stains probably weren’t the result of ice dams.  When stains also show up on gable walls, they definitely aren’t the result of ice dams.

When siding stains appear in random areas during the winter, it’s the result of moisture migrating through the walls during very cold weather, condensing as frost, then melting again once the outdoor temperature warms up.  That’s the long and short of it, but there are a number of things that will increase the potential for water stains to show up on siding.

Stains on vinyl siding

Cold Weather

The colder it is outside, the greater the potential for frost accumulation in the walls and attic.  When there is an extended period of unusually cold weather like we had last winter, the potential for frost accumulation will increase as well.

Humid Air

The more humid the air in your home is, the greater the potential for frost in the walls and attic.  Do what you can to lower humidity levels; the most obvious “no-duh” thing would be to turn off your whole-house humidifier if you have one.  A few other ways to lower indoor humidity levels are:

  • Install timers on your bathroom exhaust fans that will run the fans for an hour at a time, and use the fans.
  • Install bathroom exhaust fans in bathrooms that are used for showers or bathing if not present.
  • If the kitchen hood fan exhausts to the exterior, use it while cooking.
  • If you have too many plants (or weeds) in your home, fix that.
  • If you have a crawl space with no vapor barrier, fix that.  Crawl spaces with dirt floors are major contributors to indoor humidity.
  • If your home doesn’t have a ventilation strategy, add one.  To understand what that means, please read this excellent article by Allison Bailes at the Journal of Light Construction web site: Choosing a Whole House Ventilation Strategy.
  • Read the article I just linked to above.  Seriously.  This will make the rest of this blog post make more sense.

Combustion Air Duct Connected to the Furnace Return Plenum (AKA – “Supply Only” ventilation)

Combustion Air Connected to Return Plenum

In Allison Bailes’ article above, this would be described as a “Supply Only” ventilation system for the home.  When the blower fan on the furnace runs, it pulls air into the home via the duct that runs to the exterior of the home.  This puts the home under positive pressure.  Of course, all of that air coming in needs to leak back out… somewhere… right?  Of course it does.  It leaks through a million little holes in the walls and ceilings.  It leaks through outlets, switches, and countless other penetrations.  This is how moist air gets into the walls.  This is a bad way to ventilate houses in Minnesota.  Check out my blog post on this topic for more info: Combustion Air Duct Connected to Return Plenum

Improperly Balanced HRV/ERV

If an HRV or ERV isn’t properly balanced, it can put the house under positive pressure.  This increases the potential for air to leak into the wall cavities.

Unbalanced Ductwork

Unbalanced HVAC ductwork can cause pressure problems.  Leaky or excessive return openings in the basement can put the basement under negative pressure, while the upper levels are put under positive pressure.  As I mentioned in my blog post on frost in the attic, one simple test to find out if your basements “sucks” is to position a door to the basement about 1″ away from being closed, then turn the furnace fan on.  If the door closes by itself, it’s an obvious sign that the ductwork is not properly balanced.

There are more factors than these, but these are a few of the most obvious ones.  If a home has never had stains on the siding in the past but stains recently started showing up, you’re probably scratching your head wondering why, right?  The simple answer is that something changed, and the most likely change was that you decreased the ventilation in your home by accident.

Turning off or disabling an HRV (air exchanger) would be an extremely obvious example, but that’s a little too “on the nose”.  If that happened, you already know what you did.  A far more likely but less obvious cause for decreased ventilation in a home would be replacing an older 80% efficient furnace with a new high efficiency, sealed combustion furnace.  That will make for a major unintended change in ventilation; check out my blog post from over five years ago on that topic: New High Efficiency Furnace, New Moisture Problem.

Another common cause of decreased ventilation is having air sealing performed in the home – especially in the attic.  Attic air leaks are also known as attic bypasses.  This is actually something that is now required by law in Minnesota when having attic insulation added: Minnesota Department of Commerce: “Beware the Insulation Contractor Who Does Not Include Air Sealing”.  When these air leaks are sealed, less air leaves the home, so less air enters the home.  That means a decrease in ventilation, which means new problems will probably show up… such as stains at the siding.

Side note: I’ve been recommending Cocoon for insulation jobs for the past couple of years, because they take all of these factors into account when they work on homes.  Check out their guest post on my blog for more on this topic: Unintended Consequences of Adding Insulation.
