Causes of Attic Mold
Discovering the source of your attic mold stains can seem impossible, but identifying the cause is essential to tackle them successfully. While roof or chimney leaks and inadequate ventilation systems could be behind this problem, there may also be other causes that homeowners should consider — such as:
- High humidity levels in the attic due to poor ventilation or insulation
- Improperly installed or damaged roof flashing
- Ice damming on the roof during winter months
- Leaking plumbing or HVAC systems in the attic space
- Flooding or water damage from severe weather events
