Due to its functionality, metal roofing has become a preferred material for agricultural and industrial buildings. Although metal is a durable material, it still needs proper care and maintenance to keep it free from corrosion caused by condensation. Here’s what may be causing condensation under your metal roofing, and what you can do to prevent it.

What Causes Condensation Problems?

Condensation occurs when there’s too much water vapor, and the air can’t hold it anymore. Once the vapor reaches its maximum density threshold, it changes to a liquid form.

Condensation typically happens at night, when building interiors are warmer than the temperature outside. As the warm air touches the cold metal roof, its temperature drops. As the air cools, its capacity to hold moisture also decreases. The excess moisture then creates condensation droplets on the metal roofing, making it prone to corrosion.

How Do You Fix Condensation Problems?

Below are three things you can do to fix condensation problems and preserve the integrity of your metal roofing.

• Insulate: Minimize the condensation on your roof by insulating it. Fiberglass insulation backed by vinyl helps keep moisture from reaching the cold roof material, thus preventing condensation.

• Keep Moisture Out: Another factor to consider when trying to minimize condensation is the amount of moisture inside the building. Common sources of moisture in buildings are unvented heaters, fill dirt, livestock, and melted snow from cars.

• Have Adequate Drainage: Insufficient drainage may lead to standing water and increase moisture around a structure. So, having a system that lets the water flow away from the building can help keep moisture levels down.
