I’m replacing the deteriorating cedar shingles on a gable end of my 100+ year old home in northeast Ohio. I thought it would be a straightforward job, but I was suprised to find the shingles were nailed to the (presumably origional) bevel siding. I further determined that this part of the house was done with single wall construction, that is, the bevel siding was nailed directly to the studs. I really don’t want to install the new shingles over the bevel siding, so I’ll have to bite the bullet and remove everything. This will give me a chance to better insulate the wall cavity. My problem is clearance to other additions to the house. The question is, what is the thinnest plywood sheathing I can use on this non-weight bearing wall to adequately secure the shingles. Shear strength is not an issue and the BI doesn’t care if I use sheathing or not, since it wasn’t there origionally and he considers this a “repair”. My goal is to keep the singles from projecting out from the studs any more than necessary. Any advice or input would be most appreciated.

1/2" is all you need.
Half-inch plywood plus a product like Home Slicker (to provide air space behind shingles) adds up to about a 3/4-inch thickness. That's probably very close to the total thickness of the bevel siding, including overlap.
Thanks very much for your replies, gentlemen. Half inch plywood it is. I was seriously considering the Home Slicker, too. It's not easy to find it in my area, however. Most folks in the local building supply centers have never heard of it.
