Intake and exhaust work together
Many ventilation strategies rely on balanced intake and exhaust rather than simply adding more roof vents.
The house matters
Attic configuration, insulation, climate, roof design, and existing mechanical systems can affect the appropriate approach.
Ask what is included
If ventilation changes are proposed, ask which products will be installed, where intake and exhaust will occur, and how the design was determined.
Follow applicable requirements
The roofing provider should account for manufacturer instructions and applicable local code requirements.
