Atlas technical bulletin: Minimum Roof Deck Thickness.
What this means for your roof
Atlas requires suitable rated plywood, OSB or qualifying plank decking. Its bulletin addresses nail holding, deflection and unsupported substrates. The actual panel specification must satisfy both current product instructions and the local structural requirements, rather than relying on a nominal thickness alone.
A useful question for your contractor

Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
