Dehumidifier in attic in winter.

Using a dehumidifier and installing a perimeter draining system can further. This can result in mold rust and deterioration of wood and structural fasteners.

Attic condensation generally happens during winter spring months when warm moist air from the main living area rises into the attic space. Ventilating an attic too much can also cause problems. What to look for in a dehumidifier for an attic. When that warm moist air meets the chilly underside of your roof s deck condensation occurs.
