Several factors can contribute to metal buildings sweating including the hvac system how your building gets used the use of space heaters or faulty construction.

How to stop a metal roof from sweating.

Condensation happens when moisture filled air contacts anything that is below the dew point temperature. This in turn prevents moisture condensation on the metal roof. Metal roof insulation increases the temperature of the inside surface of the ceiling. It can lead to roof leaks even if rain has not occurred for several days.

When the temperature of the roof is lower than the air inside the extra moisture in the air condenses on the underneath of the roof. A low roof pitch say 6 degrees or less means that as condensation collects it doesn t run down the roof slope it stays put until a drip forms which drops on to your stored belongings below. Here s how to fight back against the enemy within. The impact of condensation in post frame buildings is very real.

Metal gets cold faster than other items so condensation begins on metal first. If you re wondering how to prevent condensation under a metal roof you re not alone. This is often accomplished using vinyl backed fiberglass insulation to prevent humid air from coming into contact with the cooler metal roof which may be at or below the dew point. When wet warm air comes into contact with the colder walls or the roof line of metal structures sweating results.

Owners of agricultural buildings man caves and horse barns all are worried about the corrosive effects of condensation. Traditionally condensation is managed by insulating the metal roof so that the panel temperature never reaches the dew point. The result is the roof sweating and dripping water all over your precious stuff. When then environment outside becomes cooler i e.
