Attic moisture

attic moisture causing mold in Mt. Airy, NCWhen the North Carolina outside temperatures are very cold, the air holds less moisture since the temperatures are decreasing. If there is excessive moisture accumulation in your attic it will condense on cold areas mainly on the underside of your roof and cause moisture accumulation. Attic moisture can bring mold growth to your home which can damage the structure of it. If insulation becomes damp it will ruin your walls. If you have attic moisture it is important that you handle the situation quickly to prevent mold growth and other damaging issues.

Some of the signs which indicate excess moisture in the attic include:

  • Moist or wet insulation
  • Buckled or damaged roof sheathing
  • Moisture or frost on the roofs sheathing Moisture, frost and ice buildings on roofing nails
  • Dark stains
  • Rust

How to prevent mold formation in your attic:

  • Good mechanical ventilation- good ventilation for your dryers, kitchen and bathroom helps a lot when dealing with attic moisture. Vents should always be exhausted to the exterior of the building, when these vents are not exhausted properly moist air is deposited into the attic leading to rise of humidity thus causing attic mold growth. Attic ventilation also helps to keep your attics cool and also prevent ice dams. With a good attic ventilation system one is able to control attic moisture, temperature and humidity through exhausting the moist air
  • Good insulation-Also to keep your attic cool it is also wise to consider some good insulation. Another reason for ventilation is to extend shingle life by keeping roofs cool during warm weather, it has been noted that the temperature lowers for ventilated attics compared to unventilated ones. Attics need to have a well-balanced ventilation system this consists of an intake and an exhaust. This installation method actually promotes the stack effects to move the air contained within the attic.

During cool temperatures or winter months the recommended relative humidity inside of a house should be 30-50 percent. At higher levels of relative humidity condensation can even occur inside the house on windows, cold walls or ceiling surfaces. Also moist air enters our attics from the living space below thereafter clashing against the roof. This results to condensation or even interior frost in attic. This occurring from time to time results to the wetting of the wood thus encouraging attic mold growth.
