Mold in the attic is a huge problem — they can contain a lot of your ventilation systems and, if left unchecked, can spread mold throughout the rest of your home. In your attic, check for mold
- In your insulation
- Near any vents from the kitchen, bathroom, or laundry room/dryer
- Near your water heater or furnace
- Around your soffit vents (these are the vents near the bottom of the roof that provide ventilation to the attic)
- Roof leaks will lead to attic mold. Below are a few ways to check for possible roof leaks:
- Check for discoloration of insulation and wood (e.g. rafters, sheathing, joists, attic side of fascia boards, etc.).
- Check roof valleys (i.e. where two roofs join at an angle), which are highly susceptible to roof leaks.
Poor or improper ventilation in the attic will lead to attic mold.
Much of the condensation that leads to mold growth in an attic is due to moist air move up through the ceiling.
