TinnerFlow™3rd YearRoof / EquipmentYELLOW · Check First
A sloped roof with a flat curb can set the unit out of level and create condensate/drain problems. Verify curb pitch adapter requirements before the crane set.
Rooftop equipment usually needs the top of the curb level even when the roof deck is pitched. If the curb follows the slope, pans, drains, fan sections, doors, and internal components may not work as intended.
The fix is best before the unit is set: verify roof pitch, curb submittal, manufacturer requirements, and whether a factory or field pitch adapter is required. If the unit is already set, do not shim casually under equipment without approved direction.
Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
