Controlling Moisture in Attics

Moisture in attics can damage your home and belongings. It can cause wood to rot, mold to grow, and insulation to lose its effectiveness. Excessive moisture can also lead to condensation on windows and walls, which can further exacerbate the problem.

What is a bad moisture reading?

A bad moisture reading is anything above 45%. This level of moisture can cause damage to the attic and its contents. If you have a moisture reading above 45%, you should take steps to reduce the moisture in the attic.

How to control moisture in your attic

There are a number of things you can do to control moisture in your attic:

  • Ventilate the attic. Air flow is essential for preventing moisture buildup. Make sure there are vents in the attic that allow air to circulate.
  • Insulate the attic. Insulation helps to keep the attic warm in the winter and cool in the summer. This will help to reduce moisture buildup.
  • Seal air leaks. Air leaks can allow moisture-laden air into the attic. Seal any air leaks around windows, doors, and pipes.
  • Use a dehumidifier. A dehumidifier can help to remove moisture from the air in the attic.
  • Check the roof for leaks. A leaky roof can allow water to enter the attic, which can lead to moisture buildup.
  • Install a vapor barrier. A vapor barrier can help to prevent moisture from entering the attic from the crawl space or basement.

By following these tips, you can help to control moisture in your attic and prevent damage to your home and belongings.
