Your attic may have been perfectly dry all summer. So what changes in the fall?
The temperature.
As we turn on our heating systems and outdoor temperatures begin to drop, the difference between the warm living space and the cold attic becomes more significant.
Warm, moisture-filled air can escape into the attic through small gaps, openings around fixtures, or improperly vented bathroom fans.
When that warm air meets cold roof sheathing, condensation can form.
And where moisture lingers, mold can grow.
The important thing to remember? Mold is often the symptom. Moisture is the problem.
At Quigley Attic Mold, we believe understanding why mold developed is just as important as removing it.
A little attention to your attic now can help prevent a much bigger problem later.
