garagedoor opener sheetrock falling

I had the ceiling drywall get rubbed by the garage door opener track, but not pull any down.

The thickness has to be right, also. Too thin and it would droop. .

You may have moisture in that area or there is weight between the rafters. Are you storing things up there?

Certainly it could. A GDO is heavy and if it wasn't attached properly to framing members it could cause drywall to drop.

Garage doors are quite heavy and if it is not installed properly then it will damage the ceiling. As a matter of fact it would also depend upon the ceiling type though! If it is delicate, it will start drooping sooner.
