How To Stop A Metal Roof From Sweating

Owners of agricultural buildings man caves and horse barns all are worried about the corrosive effects of condensation.

How to stop a metal roof from sweating.

Traditionally condensation is managed by insulating the metal roof so that the panel temperature never reaches the dew point. Here s how to fight back against the enemy within. The lower the pitch of a metal shed roof and also the deeper the corrugations the worse the problem of metal roof sweating. If you are experiencing mold and mildew growth damp spots on your ceilings and walls or musty odors there is a good chance that your metal roof is not properly insulated.

Condensation on metal roofs can be a problem once the weather starts to get cold. Metal roof insulation increases the temperature of the inside surface of the ceiling. If you re wondering how to prevent condensation under a metal roof you re not alone. 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. 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. 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. Condensation happens when moisture filled air contacts anything that is below the dew point temperature.

The result is the roof sweating and dripping water all over your precious stuff. The impact of condensation in post frame buildings is very real. Metal gets cold faster than other items so condensation begins on metal first. High levels of indoor humidity commonly cause condensation.

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. This in turn prevents moisture condensation on the metal roof.
