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.

Cheers!

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 !!

To answer the question of long term damage. YES !!

Unless the Carpenter ants attracted to it , fix the damage, it will get bigger every season, and that`s not to mention the mold that will settle in or possible framming failure due to it !!
