Exterior sheathing is Sheetrock -- not plywood

I'm planning on adding vinyl siding...and just discovered that I only have sheetrock under my old asbestos shingles...not plywood. Do I need to rip it all off and put in plywood sheathing? (I have seen vinyl siding coming off of more than one home in my neighborhood and think that the builder did shoddy work.) It seems plausible that vinyl siding nailed into sheetrock and not plywood will come loose over time.

If I do rip it all off, I would add some insulation before putting the plywood up... It's just a much bigger job....

You have a type of exterior gypsum sheathing. It's not drywall, but we probably all know what you mean- it was quite popular in my area in the 60's.

You don't necessarily have to change sheathing- that would be more work than you bargained for. If the contractors mark the studs, and try to nail mostly to those areas, the vinyl siding will be fine.
