All those systems can handle wall construction, but need help when it comes to the roof. Well of course we can, using just a nail-base panel like the ones used in commercial flat roofs. It has just one top skin, for attaching roofing. This works great for insulation, and in commercial construction it's quite popular. But remember, commercial roofs are mostly low-slope roofs.
Log homes have steep roof pitches, and the forces are different.
One issue is the shear force where the panel attaches to the rafter or purlin. If there's just foam where the screw goes from panel to framing, the shear resistance at that point is somewhat suspect. That gives the screw something to push against, and it lets us use glue as well as screws. In any case, most log home roofs need some structural help that a real SIP sandwich panel has the strength to provide. It's assumed that the roof structure will help.
