How Do Mold Infestations Happen in Attics?

While many people think of basements and bathrooms when they hear the words, “household mold,” the fungi can appear in many other places in the home, including the attic. Knowing how mold forms in the highest place in your residence will help your control efforts.

Clogged Vents

Most roofing systems include vents that allow hot attic air to escape instead of building up and contributing to mold growth. If these vents become clogged with leaves, twigs, animal nest materials, and other debris, such as blown trash, they no longer provide an outlet for rising hot air. The moisture-rich air stays in the attic as a result, creating ideal conditions for mold to grow. You might notice a musty odor upon entering the space, or see mold on the room’s insulation. 

Underlayment Wear

Shingle roofing systems feature synthetic or felt underlayment that provides a protective barrier between the shingles and the roof rafters. Once that layer wears away, the roof and subsequently the attic become vulnerable to water damage. If you see daylight streaming through roof rafters upon visiting your attic, the underlayment has deteriorated and your attic is at risk for water damage, mold growth, and pest infestations. Depending on the age of your roof, you might need the entire system replaced to avoid further problems. 

No Ventilation 

If your roof was constructed without sufficient ventilation, the attic becomes a center for hot, damp air. Rising air has nowhere to go and builds up, creating conditions ideal for mold growth. The roof can sustain water and mold damage as well if the attic features low-quality or no insulation because there’s nothing to keep hot air from entering the rafters. Schedule vent and insulation installations to prevent water damage and mold growth.
