Why Does My Metal Carport Sweat. Warm, wet air rises and meets the cold roof and cools. It occurs when moisture passes into a metal building’s interior and condenses below the surface.
As the metal aged and oxidized the condensate turned gray / whitish and stains the cars. When warm humid air from outside comes into contact with the cold concrete the air rapidly cools and condenses on the surface causing the wetness. Several factors can contribute to metal buildings sweating, including the hvac system, how your building gets used, the use of space heaters, or faulty construction.
Overnight when my car is parked, water drips down wherever there is a screw connecting the top to the frame.
This is unsightly as well as leading to a weakening of the materials. When temperature and humidity conditions reach dew point, moisture can condense on the underside of metal roofing and potentially cause water damage to the inside of your customer’s building. The first thing is to understand how the condensation forms in the first place. Your browser does not support the audio element.
