Moisture in attic in summer.

You want to avoid ice buildup or condensation that could lead to structural problems in your attic. It s important to keep an eye on attic moisture and temperature if you believe you have a potential problem with mold. The most common cause of ceiling condensation is an attic with too little insulation and ventilation. Even the average person produces about 3 pints of water a day while breathing.

Condensation on your ceiling can cause water damage and promote the growth of mold or mildew. The main goal is to keep your attic temperature the same as the outside air temperature in the summer as well as in winter. Attic air dew point temperature elevated above outdoors. 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.

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. As a general rule the lower the outdoor temperature the lower the recommended humidity setting. 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. Attic insulation and ventilation go hand in hand.

In summer when the air conditioning is on the reverse happens. They keep your home cooler in the summer warmer in the winter and free from damage caused by moisture. Well the same principles apply here except that your roof may be the side that is warmer in the summer. Improper ventilation and insulation of home attic space can produce high humidity levels and trap.

In an attic like this wintertime ceiling condensation can form when cold air from the attic hits your warm ceiling. The concern in summer is heat. Attic moisture is caused by hot temperatures and high humidity prime causes of mold in your attic. Extra heat build up under the roof deck can cause your shingles to deteriorate much faster sometimes cutting their life expectancy in half.

Heat from the sun radiates from your roof and vents allow warm moist air to enter your attic.
