What Causes Moisture in Your Attic??

- Roof leaks- any leaks in your roof with create moisture issues in your attic
- Poor ventilation to the outside of the home
- Leaking pipes in the attic
- Poor internal ventilation- this can be caused by dryer vents, refrigerators, and overuse of humidifiers
- Basements or foundations- moisture can travel up your walls and ceilings from the basement, so basement flooding can cause moisture in your attic
- Air conditioners- air conditioners create a lot of condensation and when not vented correctly can cause moisture in your walls and attic
- Ice damming- ice damming in the winter can cause small to large leaks in your roof that will cause water to build up in your attic
Why Is Moisture in Your Attic Dangerous?
There are many reasons that moisture in your attic can become dangerous. These reasons range from personal to structural. The number one reason that moisture in any part of your house including your attic is dangerous is that it can cause mold and mildew to build up. Mold and mildew can be very bad for the health of the people who live in the home. Mold in your home can cause you to develop several health issues among them coughing, trouble breathing, headaches, stuffy nose, diarrhea, nausea and other gastrointestinal issues. If you spend years in a home that has mold and mildew you can become very ill. Also, mold and mildew can travel from your attic to other areas in your home. This can not only cause health issues, but can require major and costly repairs needing to be done to your home.
Moisture in your attic can cause a lot of damage to your home even in the short term. If you have condensation in your attic in the winter it can cause ice damming which in turn can cause your roof to leak. This leaking can cause your insulation to be degraded quickly and also cause the trusses and other support structures in your roof to rot. Another possible downfall to having moisture or leaking in your attic is that it can cause your ceilings and walls to leak. If any of these issues occur you will need to replace degraded materials and you may even need to replace your walls and ceilings. Of course, along with all this damage you will get mold, rot and mildew, which if unattended to can contaminate your entire house.
