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?
Step flashing and diverter at the end isn't working right. The last piece of step flashing above the gutter should have a bent out piece to get water running down the wall above to go into the gutter and not just run down the wall. I'd also be very suspicious the siding isn't installed correctly there as well as it shouldn't let water behind it.
I'd get an exteriors contractor to come and look at it, and see if they can bring the two problems together to be fixed.
No diverter is present there at all. There's a bunch of things going on here that could be causing this problem and I think it would be best to address all of them at once:
