Roof Condensation in Commercial Buildings

roof condensation

If you’ve ever written a message on a foggy bathroom mirror after a hot shower, you’ve gotten an up-close-and-personal look at condensation in action. When it obscures your bathroom mirror, it’s innocent enough. However, excess condensation within the metal roof of a commercial building can create structural problems that may progress into major problems down the road.

How Does Roof Condensation Form on Industrial, Commercial buildings?

Do you have foil or batt insulation?

Condensation happens when there is more moisture in the air than the air is able to hold. The warmer the air, the more moisture it’s capable of holding. However, as that air cools, it can no longer hold the water vapor, and instead, water droplets form on any available surfaces. If your building is warmer than the outside, it’s easy for this effect to happen against windows. It can also occur very commonly around  thea roof structure.

At first glance, roof condensation might not seem like a huge deal. However, in just a few years moisture can build up around the underside of the roof structure, The roof heats up during the day and then cools off at night. When this cooling occurs the moisture gets absorbed into the wood and any metal in the roof area starts to rust and corrode. This affect Hangers, roof nailing or other metal behind the insulation.

Left unremedied, roof condensation can also harbor mold and mildew growth, and damage to all metal surfaces.
