Condensation In Attic During Winter

Attic condensation during the winter can decrease the effectiveness of insulation and over time can cause significant damage to structural elements in the attic such as rafters or trusses.

Condensation in attic during winter.

Attic condensation generally happens during winter spring months when warm moist air from the main living area rises into the attic space. In an attic like this wintertime ceiling condensation can form when cold air from the attic hits your warm ceiling. As the moisture migrates upwards to the colder attic areas during the winter months the relative humidity is increased to the point that condensation can occur on cold surfaces.
