As a homeowner, having a mold infestation in your attic—or anywhere else in the house—is a big problem. Aside from causing property damage, mold growth is a health hazard that can trigger respiratory problems. As such, it’s crucial to know the warning signs for an imminent infestation and schedule mold testing as soon as possible. Here’s what you should understand about mold growth and how to deal with it.

Does Mold Grow in the Attic Insulation?

Mold growth occurs in areas where there is biodegradable or organic material present or excess moisture. That’s why proper insulation is important in curbing a mold infestation in your home, as it helps keep temperatures dry and controlled. However, there are instances when you’ll find mold in your attic, particularly on the surface of the insulation. Fungi atop the insulation can be traced to spores that fell from the roof sheathing above and have settled on the fiberglass instead. Bear in mind that fiberglass insulation is not an organic material for mold to feed and thrive on, but when it traps dirt and dust, fungal growth is possible.

How Can You Prevent It?

For some homeowners, beefing up the insulation in the attic may seem like a good idea to protect against mold growth, but doing so is counterproductive. When an attic has excessive insulation, it can experience severe condensation since there is less radiant heat making its way inside. If there’s no heat in the attic, the roof sheathing will have a similar temperature to that of the outside air. Condensation happens when moist air comes through the attic vents and cools down as it hits the roof sheathing. Moisture then saturates the fiberglass surface, jump-starting the mold growth process. To keep moisture buildup out of the attic, ensure there is sufficient ventilation. In addition to fiberglass, use spray foam insulation for an airtight home that will minimize moisture and airflow. You can also use dehumidifiers to control moisture levels, especially during the cold season.
