A hot attic can make upstairs rooms uncomfortable and increase the workload on air-conditioning equipment. The roof covering matters, but attic temperature is controlled by several connected parts of the building.
Common contributors
Dark heat-absorbing roofing, insufficient insulation, air leakage, blocked intake vents, inadequate exhaust ventilation, and ductwork located in the attic can all contribute.
How metal roofing can help
Reflective finishes can reduce solar heat absorption, while metal sheds stored heat relatively quickly after the sun goes down. Installation details and any air space beneath the roofing can also affect heat flow.
Evaluate the full system
Before promising a solution, inspect insulation, air sealing, ventilation balance, roof geometry, and existing moisture conditions.
