ZIP roof sheathing, plywood + Blueskin for walls?
Driving by a new zone 5 build today and noticed this sheathing combination. Roof looks to be 5/8 ZIP with taped seams. Exterior walls are plywood + Blueskin. If I trust ZIP system for the roof sheathing, why the extra time and materials for plywood walls + Blueskin?
Last year I was following a Cape Cod shoreline build that did ZIP for roof and walls.
