What may be any typical local code variations to expect for the international building code and what does the code it’s self call for on re-skinning a roof deck.
I’d like to get away with using 1/4″ osb that I have enough of laying around all ready.
Current decking is absolutely fine structurally. Not a water mark, split, or bow to be found. Only problem is covering 3″ spacing between planks. Old style 16′ long 1″ – 3/4″ x 16″ (yes 16″ wide) planks. Framing is original true 2×4’s rough sawn on 2′ centers. Roof is a 12/12 pitch 14′ by 32′, in Michigan.
Can I get away with the 1/4″ or do I have to use 7/16″?

I don't know what the code says, but I'd worry about the ability of 1/4" OSB to hold a nail.
I won't be laughing at the lies when I'm gone,
And I can't question how or when or why when I'm gone;

So I guess I'll have to do it while I'm here. (Phil Ochs)
Well ya that was my only concern outside of the inspector. I figured on depending how the coursing falls and adjusting slightly higher or lower were I nail, anything landing within that weaker 3" strip can be minimized. Than since it's only 3" that the nailing could land in, the single would still be secured in the upper portion by the following course nail line. Plus once all the tar strips have bonded making the roof one unit, I think the 1/4" osb holding a nail isn't as troublesome. After all, the holding power of an 1 1/4" in 1/4" osb on one line and real lumber the second nailing line can't be worse than the staples that use to be used, that have more or less out lived (stayed in place) over any shingle deterioration and needing to be replaced.
nc.... like was stated... the problem is the nail holding ability... ask your BI if you can use a double layer of 1/4"... since you already have itMike Hussein Smith Rhode Island : Design / Build / Repair / Restore
That's might be the best option now that you mention.
Talk to the BI and see what he/she will allow. A few years ago I did a roof like yours. I pulled and moved the decking to eliminate the gaps and reused lumber to finish off the resulting uncovered area. No sheeting.
Had considered and would love too. The extra work just isn't feasible for me at this time. It's a 3 story 12/12 with no option but roof jacks on that side. Not into that so I've got somebody else doing that side.As for the BI I'd prefer as little involvement as possible. It's my own house broke out into rentals in varying stages of remodel. Already hit for no permit on roof and if he want's a finial he'll have to go through one of the Apartments to get to it. Just taking lots of pictures and not calling for finial. Playing dumb HO since none of the paperwork or permit say anything about calling for inspections.
...16' long 1" - 3/4" x 16" (yes 16" wide) planks.
Why don't you use those amazing boards for something more usefull than roofing? Do they look good? Could they be recycled for something else?
Taday what we HAVE is an abundance of amazing sheet goods that work great for roofing applications. What we seem to lack is an abundance of 16" wide planks that are 16' long!
