Q we recently installed a zip system roof over roof trusses spaced 24 inches on center. Their installation diagram also shows h clips although tongue and groove edges or blocking is noted as an alternative in the text above. The connection between the roof sheathing and the structure is a vulnerable point that is known to fail during a hurricane.

Spaces between panels are typically created by tacking 8d nails above the last course before installing the subsequent course. The lumberyard told us to install h clips as for conventional sheathing but after taping over all the seams between panels we found that water leaked through the tape at almost every clip.
