Black Mold in Attic



If you've discovered mold in the attic, you're not alone. Attics are one of the most common places in a home where mold thrives due to poor ventilation, roof leaks, and trapped moisture. One of the most feared (and misunderstood) types is black mold in attic spaces — but not all black-looking mold is toxic. So, is it dangerous? How much will removal cost? And what are your options? This blog answers the top questions about mold in the attic, from identification to full mold remediation in attic.

Is Mold in Attic Dangerous?

Mold is a type of fungus that spreads through airborne spores. While some types are harmless black mold in attic environments, others — like Stachybotrys chartarum, the infamous "toxic black mold" — may release mycotoxins and cause respiratory symptoms, especially in vulnerable individuals. Whether it's black or white mold in attic insulation, prolonged exposure to any mold should be avoided.

What Does Mold in Attic Look Like?

What does mold in attic look like? It varies. You might see dark streaks, fuzzy white patches, or blotchy gray areas. Common mold in attic settings includes Aspergillus, Cladosporium, and Penicillium — each with different color profiles. Whether it's white mold in attic or a more sinister-looking black stain, the key is to identify moisture problems and take action.

Keep an eye out for:

• Musty odors
• Discoloration on rafters or sheathing

• Ice damming
• Poor ventilation
• Inadequate insulation (especially if you see mold in attic insulation)
