Adequate Attic Ventilation Can Reduce Your Home’s Risk of Winter Damage
You may not know it, but a lack of attic ventilation could be putting your home at risk of all kinds of damage. Namely, damage from increased moisture compromises the building’s structure without an effective attic ventilation system in place. Further damage may result from mold growth and ice dams. Learn how attic ventilation improves conditions within the home.
Moisture and moldDuring the heating season, moisture control is essential. Moisture in the attic not only leads to damage to the wood structure, causing wood rot, but it eventually leads to the growth of mold in the space, a hazard to home occupants’ health and the health of the attic. Here’s how moisture develops in the attic:
- When warm, humid air from the interior of the home is able to access the attic, the warmer air condenses when it meets the cooler attic walls and other spaces.
- This warm air holds more moisture than the cooler air around it, which is released as water vapor and then accesses the dryer, porous wood in the attic.
- Without ventilation, this condensation builds up, eventually rotting wood, compromising the sub-roof, causing exterior paint to peel and more.
