Plywood for roof sheathing
Roof sheathing panels must support trades during construction and design loads in service. Thickness and grade stamps (where required) should match engineer tables; export plywood may be used when local approvals accept mill documentation.
Loads and spans
Heavier cores increase dead load; verify against truss or rafter design. Use weight-per-sheet specs at your chosen thickness.

▶What thickness of plywood is used for roof sheathing?
Thickness depends on span, finish system, and local code or OEM requirements. Browse our thickness-specific spec pages or use calculators with your engineer’s design values.
▶How do I estimate container loads for a project?
Start from sheet count and thickness, then use the container packing calculator with your core density and panel size.
