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.

A thin layer of moisture versus large water droplets can mean the difference between a future major roof repair or not. During the winter attic condensation can turn into frost. Sometimes attic condensation is the result of an attic being improperly ventilated. This accumulation can leak through the attic floor and into your living space.

Attic condensation most commonly occurs when warm moist air from other areas in the home rises into the attic space.
