How to attach Roof Sheathing?
I live in tornado alley, and FEMA has a lot of ideas about things here also. If you want to screw the decking down, by all means, get after it....my first thought was why would you want to? If high winds are a real concern, use screws at the eaves and gables,,,nail the rest. When roof fails, it is "peeled" up, and this, must fail on an edge. What typically happens is the decking doesn't fail, the rafters fail and the decking takes the entire structure with it.
