New exterior OSB

New to DIY stuff as a new home buyer. In the process of vinyl siding, I'm taking down the T1-11 and replacing with OSB.

do I need to remove the windows so I can properly flash with house wrap or retrofit flashing?

Why are you taking down the T1-11?

It is rotted out in some spots and the contractor said if it was his house he'd take it down. (He already knew I was doing myself so he had no financial gain to say so). There was damage to some base plates and studs so he suggested we needed to see everything behind it.

If the windows are new build windows, they will have a lip which is installed over the sheathing and you will have to remove them. If the windows are replacement windows, those are screwed to the rough opening framing and not attached nor covered by the sheathing.

If the T1-11 is both siding and sheathing,(a very bad idea for an occupied dwelling), you will need to look at how the windows were installed.

I was going to say exactly the same as HandyMac. Post up some pics and they should help as well.
