If insulating, a vapor barrier should be applied on the warm side to prevent warm moist air from penetrating and coming in contact with the cold surface. Areas like attic spaces and gaps between the ceiling and roof deck (or plywood) are common areas of focus. To control condensation it's important to properly ventilate and/or insulate your roofing system. How Do You Control Condensation? Insulation and a Vapor Barrier This damage could be in the form of either premature corrosion or mold. If condensation occurs inside a roof system, it may not be able to evaporate quickly enough before it begins to cause damage. When the air inside your home is warmer than the air outside, and the roof system isn't properly ventilated, condensation can occur. When the warm air can no longer retain its moisture, the moisture is deposited on the cool surface. When warm moist air comes in contact with a cold surface, the air reaches a temperature near the cold surface where the air can no longer hold the moisture. The science behind condensation is not overly complicated.
