Metal roofing tends to develop condensation when the inside atmosphere doesn’t match the outdoor temperature. Known as sweating, it causes the water vapor in the air to turn to liquid once it cools, leading to a layer of tiny droplets across the surface. Allowing the moisture to stand for too long can cause to rust that requires roof repairs, so it's important to know how to reduce the risk of a problem.

How Can I Stop My Metal Roof From Sweating?

1. Increase Ventilation

Heat rises, which means any roof that lacks ventilation will become susceptible to condensation. The air has nowhere to go and will simply collect until conditions change and allow for thermal transfer. Installing additional vents will help increase circulation and even out the temperature. The vents will direct the excess heat through to the outside without having to touch any of the materials.

2. Keep Moisture Out

Improving drainage is another step to preserving the condition of your metal roof. Any puddles that develop along the foundation are at risk of seeping into the concrete and producing a damp atmosphere. Installing a gutter system will redirect the runoff and ensure that it collects well away from the structure. Extend the downspouts to prevent accidental erosion in the lawn.

3. Adjust the Roof Pitch

If your roof isn’t angled correctly, then the condensation that develops will simply remain in one place. The constant moisture will raise the indoor humidity and cause the issue to worsen. Increasing the slope will allow for more natural circulation and keep the condensation moving in a downward direction. 

4. Add Insulation

Buildings that don’t have enough insulation will experience regular fluctuations in temperature. Adding a layer of material creates a barrier that prevents the two extremes from ever coming into contact. This will reduce the risk of condensation and extend the lifespan of your roof.
