Attics are a liability zone. When roof sheathing sits above safe moisture thresholds, growth follows—triggering inspection issues, buyer objections, and warranty work. A clean-and-seal system stabilizes the deck and cuts risk.

  • Unsealed roof decks absorb and retain moisture during dry-in and seasonal humidity swings.
  • Improper exhaust routing (bath/dryer vents dumping into the attic) injects warm, moist air—often against code.
  • Blocked soffits / missing baffles trap vapor and slow drying across the roof deck.

Common Problem Indicators
