This is a 2008, 2-story home in North Carolina. This damage is on the first story. There is a front porch and the roof covering it developed a leak. It has been delivering water into the soffit and behind the building wrap.
From inside the crawlspace, there is no evidence of water intrusion. In this picture, the rim joist is discolored, just starting to rot on one spot, but appears fine. From inside the living space there is no evidence of damage.
Stud labeled 1 is the wall stud. Studs labeled 2, 3, 4 are shorter studs that appear to be supporting 2x10s seen in other pictures. 3 and 4 definitely need to come out, 2 probably needs to come out, and 1 appears to be fine at this point.
This is where the worst rot occurred. Label 5 is for two sistered 2x10s. Both will have to be replaced. These extend out and connect to the front of the porch roof over a column, which I assume is a load-bearing column.
Label 6 shows a void where there was a 2x4 attached flat to the 2x10s. It was wrapped in aluminum. I am assuming it was strictly for the wrap and of no structural importance. Does that sound right? It was lying on top of the brick veneer. As for the veneer, unfortunately I will have to remove some of the brick to replace damp sheathing behind it.
A pic of things before I removed everything to the ground.
So, my main question surrounds the four studs on the corner. What do I need to support so I can safely take out the ones labeled 2, 3, 4? Is there anything from the second story they would be supporting?
For any affected wood that is not replaced, would it be wise to paint it with a copper-based preservative?
