Why is metal roof sweating?

Condensation forms when warm, moisture-laden air hits a cold surface. In the case of metal roofs, it happens when warm, moist air from inside the house is driven into, and trapped inside of, the cavity beneath the roof. When the metal roof’s temperature drops at night, the air condenses on the underside of the roof.
