I have just (mostly) completed a high-bay garage for a customer who now wants me to put 5/8″ T1-11 on the ceiling. Trusses are set at 2′ oc. I have no experience with this application; should I be concerned about sag over time (and a callback)?

I know you’d have no problem with 3/8” rough sawn (fir) plywood running the long way across 2’ framing…..
At 2’ wide overhang soffit.
Any buckling on your long edge across the 2’oc truss would be possible I guess. We used clips between 2’ centers for 1/2” roof sheathing to keep them in line.
Bears me. Hopefully somebody sees this that’s done it and can advise.
