Metal buildings such as sheds, pole barns, and garages often develop condensation on their exteriors due to excess humidity, as well as differences in interior and exterior temperatures. This moisture can lead to rust and mold growing on the roof and siding of your building, compromising its integrity and potentially causing respiratory issues when you are inside. Below is more information about how to prevent this condensation so that you can maintain the structure.

4 Ways to Keep Condensation Off Metal Buildings

1. Promote Circulation

Because heat rises, the ceiling of your metal building should feature vents that allow warm, humid air to exit, minimizing condensation. These have fine mesh screens that prevent pests from entering the space, while allowing moisture to escape.

Also, you can improve circulation and water evaporation by running portable fans throughout the area. If your building does not have electric outlets, leave the doors open when you are working to facilitate airflow.

2. Insulate the Interior

Vinyl-backed insulation acts as a barrier between the interior of the metal building and the outside elements. It will help maintain a consistent indoor temperature so that condensation cannot form when cold and warm air meet. You should install this material on the underside of the roof and the interior of the siding to limit heat transfer. 

3. Repair Roof Leaks

Damaged or missing metal paneling on the roof will allow rainwater to enter the space. When this happens, the indoor humidity will increase and insulation will get wet. Wet insulation cannot effectively stop heat from transferring, which will allow the moist air to condense and rust the building.

Inspect your roofing materials from the ground often, and look for rust and holes. If you find any, repair the damage promptly to control indoor moisture. 

4. Install a Dehumidifier

If you still experience condensation inside your building, consider installing a dehumidifier to remove excess moisture from the indoor air. You should primarily run it during the spring and summer, since the air is typically more humid.

Also, you can prevent moist air from entering the space by sealing any gaps or holes you find around doorways, windows, and foundation sills. The best way to do this is with expandable caulk or weatherstripping. These materials have the added benefit of preventing pests and rain from entering the space.
