Metal Porch Roof Condensation

When then environment outside becomes cooler i e.

Metal porch roof condensation.

This in turn prevents moisture condensation on the metal roof. Metal roof insulation increases the temperature of the inside surface of the ceiling. Metal roof condensation especially with a tin roof can cause serious problems when the metal sweats or rainwater collects under the tin panels. The result is the roof sweating and dripping water all over your precious stuff.

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. By adding insulation to the internal surface of the metal then the dewpoint is less likely to be met. When this happens the tin roof can rust and even warp. Worse if the roof is over your shop carport barn or self storage unit you have to worry about what damage it is doing to the contents of these buildings.

Two common types of metal roof insulation are. The reason why condensation forms on the metal roof is that it s temperature is below the dewpoint of the internal air. Have you ever been under a metal roof that had condensation on the bottom side of it. Essentially condensation occurs at night when the temperature inside a building is warmer than outside.

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. At night the thin metal in the roof quickly cools down. Condensation on metal roofs can be a problem once the weather starts to get cold. That excess moisture ends up as drops of condensation on the roof.

Metal gets cold faster than other items so condensation begins on metal first. Condensation happens when moisture filled air contacts anything that is below the dew point temperature. Traditionally condensation is managed by insulating the metal roof so that the panel temperature never reaches the dew point. It can lead to roof leaks even if rain has not occurred for several days.

Insulation you use needs to be closely bonded to the metal. Condensation can cause your ceiling to rot. Picture a cloud of moisture floating overhead between the rafters. It is quite annoying to have the condensation falling on you like rain.
