Attic moisture typically occurs in winter when windows are closed and living spaces are heated. During winter, indoor air can be dry leading to the use of humidifiers. As a result, water vapors from humidifiers as well as other household activities like cooking, cleaning, and bathing activities are carried up into the attic via heated air. This moist warm air releases water vapors in the attic that collect on hard surfaces which over time can lead to problems.
MOISTURE BUILD UP
Moisture build up can lead to mold growth which can be especially difficult for occupants that suffer with breathing conditions, the very young, the elderly and those struggling with declined immunity or other health issues.
Moisture build up overtime can lead to deterioration of your roof structure, often causing thousands of dollars in repairs which are typically not covered by homeowners insurance.
EARLY SIGNS OF MOISTURE PROBLEMS
If you notice condensation on interior windows during winter, there is a good chance your home is too humid. Turning down the humidifier will help but it won’t fully address moist air from gathering in the attic.
