Gauging the Moisture Level of Your Attic

moldy insulation

Hot temperatures and high humidity are the prime causes of mold growth in attics, although roof leaks can also spell disaster for your home’s uppermost level. If you think the ideal conditions for mold and mildew are present in your attic, there are a few at-home tests you can perform to gauge the moisture level.

Step #1: Consult a thermometer.

An excessively high temperature in your attic allows the air inside to hold more water vapor. Depending on the climate and level of insulation and ventilation in your attic, temperatures can reach up to 150 degrees Fahrenheit.

To properly gauge the temperature of your attic, you should use three thermometers – one in the middle of your attic, one near your attic entry and one at the far end of your attic – then record and take the average of these temperatures. Based on your location, a significantly high number could indicate a potential moisture problem – especially when hot, humid air is allowed to cool and create condensation.

Step #2: Check for excessive moisture.

While there is a special device, called a hygrometer, that can measure humidity, this instrument is not a common household item and can be hard to interpret. Fortunately, you should be able to gauge moisture levels in your attic via a visual inspection. If there’s condensation on attic windows or surfaces are wet to the touch, the humidity of your attic is too high. Colored spots, musty odors and other signs of mold can also be detected with simple observation.
