Mold in Attic
Discovering mold in your attic is concerning. It indicates ongoing moisture problems - often from roof leaks or poor ventilation - that need to be addressed along with the mold itself.
Schedule a professional inspection within the next few days.
How to Identify This Problem
Look for these warning signs:
- Visible mold growth on rafters, sheathing, or insulation
- Musty or earthy smell in attic or upper floors
- Dark staining on wood surfaces in attic
- Wet or damp insulation
- Increased allergy symptoms among household members
- Condensation on attic surfaces
- Frost on underside of roof in winter
Common Causes
Roof Leaks
Even small leaks provide the moisture mold needs to thrive. Water can travel along rafters before dripping, making the source hard to find.
Poor Attic Ventilation
Without adequate airflow, moisture-laden air becomes trapped, condensing on cool surfaces and enabling mold growth.
Bathroom Fans Venting to Attic
Exhaust fans that terminate in the attic rather than outside dump warm, moist air directly where mold thrives.
Dryer Vents to Attic
Improperly routed dryer vents add significant moisture to attic spaces.
Missing Vapor Barriers
Without proper vapor barriers, warm moist air from living spaces migrates into the cooler attic.
HVAC Equipment Issues
Leaking ductwork or AC units in the attic can introduce moisture through condensation or direct leaks.

Frequently Asked Questions
Can I remove attic mold myself?
Small areas of surface mold (less than 10 square feet) may be treatable by homeowners with proper safety equipment including N95 mask, goggles, and gloves. However, professional remediation is recommended for larger areas, any mold on porous materials like wood or insulation, or if you have health concerns. DIY removal does not address the underlying moisture problem.
Will attic mold spread to the rest of my house?
Attic mold typically stays in the attic due to the air barrier between living spaces and attic. However, mold spores can travel through air leaks around light fixtures, attic access doors, and ductwork. Addressing attic mold is important to maintain healthy indoor air quality.
Does homeowner insurance cover attic mold?
Coverage depends on the cause. Mold resulting from a covered peril (like sudden storm damage) may be covered, while mold from gradual leaks or maintenance neglect typically is not. Review your policy carefully and document any sudden water intrusion events.
