I have discovered that my house has no sheathing! It's is cedar sided and there appears to be 1" white styrofaom attached on the inside then the insulation. Is this normal?!?!
I am considering having the cedar siding removed (It is not in very good shape) and replaced with TekWall vinyl siding. WOuld it be worth is to have the house sheathed when I have this done?

Lace of exterior sheathing was common for homes built in the 'old days' but should not be the case today. Sounds like a whole lot of work. If it is an'old house', may be worth the effort and update any old electrical wiring at the same time.

The 1" of Styrofoam is your sheathing, Do you think that vinyl siding is going to hold up better than the cedar that you are replacing?? You might try Hardiplank siding, it will give a better appearance and do a better job of keeping out the weather.

I would say yes on the sheathing if you have the budget for it. If the stuff underneath is fine then use it, it holds up fine and provides a touch of insulation. On the other hand if it is deteriorated and soggy then you pretty much don't have a choice. I would also install tyvek over whatever underlayment you decide to do, that will help keep the wind out.

I used a similar product when I added a family room to my house at that time. The existing house was a track house with T 1-11 siding applied direct to the studs. I wanted a "warm room". I framed the addition with 2x4's set 2" back from the edge of the sub-floor, I then applied 2" Celotex insulating board to the 2x4's I ended up with something like an r-30 wall structure. I set in 1x4 diagonal bracing in the corners for shear strength and covered with T 1-11 to match the rest of the house.
Just because it isn't plywood doesn't make it bad or wrong. Just a note the addition plans and structure were fully approved and inspected by the city building inspector.
If you are worried about nailing cover the Styrofoam with ½" CDX and go from there.
