Roof is galv-alum standing seam. Eaves I'm not sure if I'll vent. There's just a minimal attic space, I might go spray foam. Soffits will be covered by more cement board. On a lot of commercial buildings they now require x-sheetrock or densegold beneath the siding before the sheathing. This would give another 30 min fire wall. I haven't seen it done residential and I'm not super keen on the additional cost.
