Remember the example of the cold glass in the summer.

Moisture in attic in winter.

First warm and moist air rises up from the living space below and gets trapped in your attic space. If it s winter and it s much colder outside as is often the case when that warm moist air comes in contact with the cold underside of your roof deck you get condensation. 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. It is unlikely that under these conditions normal attic ventilation would effectively remove this moisture laden air before ice formed on the roof decking.

Quelch the heat wave. In the winter the condensation will form frost and in the summer this condensation can grow mold. Warm and humid attic air combined with cold outside temperatures leads to condensation which can form on any cold wood surfaces metal nail heads chimney surfaces ventilation pipes and even in the insulation. If there is excessive moisture accumulation in your attic it will condense on cold areas mainly on the underside of your roof deck.

Warm air simply holds more water vapor than cold air. Moisture from daily activities such as cooking bathing and laundry can rise into your attic especially in winter when windows and doors are closed. Ideal attic temperature and humidity settings cold outdoor temperatures affect attics. Our main concern in the winter is moisture.

So they equalize pretty quickly. Attic moisture in winter moisture vapor from daily activities such as cooking bathing and laundry can rise into your attic especially in winter when windows and doors are kept closed. The first signs of a condensation problem in your attic might show up during a re shingle on your roof. If there are signs of rot on the roof sheathing then there has been prolonged moisture in the attic.

Hot summer weather poses the opposite problem for maintaining recommended attic temperatures. These moisture vapors can build up on attic surfaces including the underside of your roof rafters and settle on attic insulation. If it s cold outside and warm air from indoors makes it to the underside of your cold roof this air begins to decrease in temperature and releases it s moisture content along the way. Looking for signs of moisture.

The difference in the two spaces is the dry bulb temperature. Condensation in attic in winter. Cold outdoor temperatures especially below freezing can wear on your furnace. By adding moisture to the lower floor you increase the partial pressure of the water vapor which pushes it to areas of lower vapor pressure like the attic.
