Moisture in attic in summer.

Condensation on your ceiling can cause water damage and promote the growth of mold or mildew. You want to avoid ice buildup or condensation that could lead to structural problems in your attic. Step 1 check for excessive heat. As a general rule the lower the outdoor temperature the lower the recommended humidity setting.

Improper ventilation and insulation of home attic space can produce high humidity levels and trap. Advani is adding moisture to the air with a humidifier and that hot air rises finding ways of getting into the attic sullivan says. Extra heat build up under the roof deck can cause your shingles to deteriorate much faster sometimes cutting their life expectancy in half. This is ok unless again you have breeches into your living quarters that allow your air cooled by your air conditioner to come into your attic.

Air leaks in the lower part of the house in the basement for example allow outside air with low humidity to get into the house. These sources are generally not a huge contributor to excessive moisture in the house or attic unless the amount of moisture is unusually high the house is extremely tight or proper venting is not used. In an attic like this wintertime ceiling condensation can form when cold air from the attic hits your warm ceiling. Heat from the sun radiates from your roof and vents allow warm moist air to enter your attic.

Attic insulation and ventilation go hand in hand. In summer when the air conditioning is on the reverse happens. Lower attic air relative humidity due to sensible heat gain by solar higher air relative humidity at the surface of wood framing materials resulting in moisture being desorbed by the attic. The most common cause of ceiling condensation is an attic with too little insulation and ventilation.
