Re: Repairing OSB underneath vinyl siding
Probably the easiest thing to do will be to replace the vinyl and OSB with T1-11 siding. You'll get the structural value from it that you're currently getting from the OSB. From there all you have to do is prime and paint and you're good to go.
You'll probably want to include house wrap in your siding replacement if there is none currently. You'll probably have trim work to do around doors and windows as well.
