My detached garage with metal siding has 2x4 trusses spaced 4 feet on

If the trusses are spaced 4' on center, you have much greater worries than
any
ceiling you might put up there. That's *much* too far apart to adequately
support the *roof*.

Did you mean 2' on center?

Its all in the truss design. My barn has trusses on 10' centers and a 50
#/sq.ft. snow load design. Way plenty to hold a ceiling too,


So your barn roof is supported by purlins as well?

But knowing this guy, his building will fail with the first heavy wet snow.
maybe he lives where snow don't fall.
