An overabundance of moisture can be a problem for metal roofing. While some metals like aluminum are naturally resistant to rust, and other metals are galvanized for protection against the elements, water can still corrode the fastenings of a metal roof or any areas where the coating has been damaged. This means that when water begins to collect on the underside of a metal roof, it can be a serious issue for your metal roof. Here’s what you need to know to fix it.

Causes of Metal Roof Sweating

The “sweat” found on the underside of a metal roof is actually condensation, which occurs when warm air — which holds more moisture than cold air — from inside the building rises and begins to condense on the colder roofing material. This process usually occurs at night or throughout the day during fall and winter, when the outside air is far cooler than the air within the building. This leaves behind enough water to potentially damage and corrode the metal roofing.

Remedies for Metal Roof Sweating

For condensation to accumulate on the underside of metal roofing, warm humid air will rise and make contact with the cold, metal roof. That's why a dehumidifier can help remove moisture from the air so that, as warm air rises, the process of condensation can't occur. Another remedy could include installing ventilation in prime locations to allow the air to escape, along with the water it carries. Finally, insulating the interior part of your roof can help prevent the inside of your building from reaching dewpoint, which is the temperature at which water condenses.
