I have a problem with flashing that has pulled down and no longer protects what it is supposed to…hard to explain, will try to attach a picture.
Basically, the 5 yr old home has a concrete porch and there was flashing installed, running up under the siding. The porch has settled about 1.5 – 2″, and that has pulled the flashing down with it, and now you can see the OSB through the gap at the top of the flashing. This area is set pretty far back, only gets wet in very windy storms.
So…what to do? Nothing? Put a small piece of new flashing up in there? hope the image helps; I don’t feel like I have explained it very well.

The easiest solution would be to slip some more flashing behind the siding and in front of the existing flashing.
You may or may not want to concern yourself with the causes behind the sinking slab.

that's what I was thinking ...
"counter flash" .... then think about handeling the real problems.

The metal in your picture was used as a barrier between the concrete pour and the wood components (assume box sill) of the house. Not as a water flashing.
Without a high quality caulk applied at the metal/concrete intersect there would be a leak capacity to the area under the slab that may result in frost heave or water intrusion into other areas of the main house.
Now that the slab has dropped 2" you have the sheathing exposed to the weather and have opened the framing system to more water intrusion.
Add that second flashing immediately to stop any water intrusion, but more important is to understand why the concrete porch slab is sinking and find a way to stabilize the situation.
How old is the house? Waht is the composition of the siding, as seen in the picture?
How long for the subsidence to show? Does the porch still slope enough to drain the water away from the flashing?

I will add the new flashing & caulk it. Regarding the sinking effect, we will have to see where it goes from here. House is 5 yrs old. Porch still has enough slope to drain. I think I will take some careful measurements and compare them in a year. I have not noticed any change in the year that I have owned the home. Oh, and the siding is cedar. Thanks to everyone for the input.
Eventually you may want to get the slab mud-jacked. Especially if it loses it's slope, as it very likely will do.
