Roofing Question

Well, if the winds and sheer force are great enough to rip off T&G, a

That's not the concern. The concern is the house and or roof twisting
in a high wind or quake and buckling, because it is not stiff enough.
There are two popular methods of making a house stiffer without adding
significant mass. One is to sheath with barn board or similar on a 45
degree diagonal. The other is to sheath with plywood or OSB.
