I’m residing my house, which is 35 years old.
I’m patching the sheathing in several places, because I’m moving doors and windows around, and I was hoping not to have to replace all of the old sheathing.
But… the thickness of the old sheathing is halfway between 1/2″ and 5/8″ plywood. So, if I use 1/2″ the old sheathing will stick out, and if I use 5/8″, the plywood will stick out. It looks like enough of a difference to me that the siding won’t lay right.
Is there any reasonable way to deal with this without tearing off all of the old sheathing and starting over?

Hi pm;
You don't say what kind of siding you are using. Some are much more forgiving than others. a difference of 1/16 - 1/8" really is not a lot on a large wall.
If you are truly concerned, use the thinner plywood, and build it out from behind. Either adjust the new studs that are patched in, or try folding up a few layers of roofing felt and using that for a shim to gain a little bit. If it's 1/8", you could buy some plywood or panel that thick and rip it down to go over the studs.
Good luck.
