How to Get Rid of Mold in Your Attic

Although common, attic mold often grows undetected for months or even years. Mold in an attic can’t be overlooked as it may be harmful to your home and health if left untreated.  

And just like the mold itself, the cause of growth is often undiscovered until the problem has grown. Usually, mold growth may be traced back to a leak or a problem with a home’s ventilation or insulation.  

We can’t understate the danger mold poses in a home. Learn what to do should you discover mold in your attic and how to prevent future problems.  

Why Is There Mold in My Attic? 

Mold thrives in moisture. In winter, your home’s HVAC system is designed to produce warm, moist air to keep your home at a comfortable temperature and to make the air moist enough to breathe comfortably. But, when warm, moist air rises, it meets the cold air in your attic, creating condensation against your attic sheathing and floor. This dampness makes your attic a prime location for mold growth.  

Aside from condensation, other scenarios may lead to mold growth. These include:  

  • Roof leaks. As your roof starts to age, natural wear and tear can cause water to seep through where it normally wouldn’t. Part of this is due to shingles lifting, weather damage, debris buildup, and more. Your attic will suffer the most from direct roof leakage. 
  • Siding/window leaks. Having improper seals or damaged windows and siding can allow any external or internal moisture to collect and sit.  
  • Air leaks. Because air contains water vapor, this moisture can get trapped in improperly sealed areas.  
  • Plumbing leaks. Pipe leaks can be tricky to spot but can cause problems and trapped moisture. If you see a wet spot on your wall or notice any water flow issues, you may need a proper inspection. A sewage leak, on the other hand, is an emergency concern and should be managed by professionals. 
  • Vents. If vents are blocked up or allowing improper airflow, hot air can collect and create condensation.  
  • Insufficient insulation. The hot air that rises from insufficient insulation can get trapped in your attic and mix with cold air to create condensation. 
  • Excessive moisture. Whether it’s a combination of these other factors or an overly warm home due to improper heating, ventilation, or humidifying, excessive moisture can become trapped in unwanted areas.
