Hey folks, looking for some advice because I don't know how to proceed.

This house came with vinyl siding and I noticed rot under it. The rot terminates up high behind where this soffit meets with the exterior wall. I need to get in here to figure out how water is getting in and then make necessary repairs, but the soffit is really in the way.

I've already removed the rot lower down - I had to remove vinyl siding, a layer of foam board, a layer of rotten OSB, the original rotten siding, and the original rotten sheathing. All of those layers are still present behind this soffit.

When I take the soffit vent off, there's a layer of OSB directly above it. Really don't know how to gain access here.

Any ideas?

I'm almost positive it's a flashing/counter flashing failure on the roof above the soffit. It almost always is. One bad piece of flashing halfway up that roof could be it. Check that the gutters aren't holding water though. If the siding detail behind the gutter endcap is bad, and the gutters endcap is leaking, that could do it. And remember water doesn't always run downhill. That shit can and will go straight up a wall if the circumstances are right.

You were correct. It was indeed an improperly done piece of kick flashing at the very bottom near the gutter

Yoooo! Blind squirrel and nuts and all that. Now the fun part, gotta go check the rest.
