It’s easy to ignore mold when it’s growing where you can’t see it. Mold in the attic may not seem like a big deal, but mold growth results from excessive moisture in the attic, which also can be highly damaging to structural elements and fixtures. Water intrusion may lead to rotted wood, bubbled paint on the home’s exterior, warped shingles, and ruined insulation in addition to mold growth. The best way to prevent these issues is to seal leaks in the attic while improving attic ventilation.
