Condensation In Attic During Winter

This attic hatch is not only leaky it has no insulation above it.

Condensation in attic during winter.

The reason is that during the winter fans such as the one in your bathroom would send air saturated with moisture into the attic directly onto frigid roof boards. If you have a roof leak in the winter months and it s not being caused by ice dam there may be another culprit. If you find find condensation on your windows this could be a n early indication that your humidifier is the source. 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.

Attic condensation the conditions that cause ice dams often cause attic condensation too. Improper ventilation and insulation of home attic space can produce. 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. Mould is caused by moisture that condenses on the cold hatch surface during winter.

In summer when the air conditioning is on the reverse happens. In an attic like this wintertime ceiling condensation can form when cold air from the attic hits your warm ceiling. And the same factors that cause attic condensation problems also cause ice build up on roof edges which can lead to ice damming. It is unlikely that under these conditions normal attic ventilation would effectively remove this moisture laden air before ice formed on the roof decking.

Many people run humidifiers in their home during the winter if they feel the air is dry. While this is fine on occasion overuse can create excess humidity resulting in condensation. Condensation on your ceiling can cause water damage and promote the growth of mold or mildew. When that warm moist air meets the chilly underside of your roof s deck condensation occurs.

Improving your attic s air sealing and insulation prevents attic air from reaching your ceiling and it s a fairly easy job to do yourself. You may pay an ice dam removal company to melt the ice dam off your roof only for the leaking to continue. This can result in mold rust and deterioration of wood and structural fasteners. Our main concern in the winter is moisture.
