Top causes of attic moisture. Animal intruders such as bats or squirrels or water leaking through the top floor ceiling. Clothes dryers venting air to the attic rather than outside. While fiberglass is technically waterproof inside an enclosed attic the thick batt retains moisture which degrades its thermal resistance properties.

For many years building codes have required high levels of attic insulation making attics less than hospitable places. Inadequate ventilation attics must be vented to allow moist warm air to escape. Air conditioner condensate pan not draining. Let the insulation dry out.

Moisture trapped inside of insulation is a breeding ground for mold and bacteria. Saturated insulation typically loses at least 40 of its insulating r value.
