You simply cannot over-estimate the importance of proper ventilation. Your roof is designed to have proper ventilation.Inadequate ventilation allows formation of condensation, moisture accumulation, and damage to the roof deck and much more.Inadequate ventilation can also affect the health of your family
To fight the enemies of, heat and moisture you must ventilate. Moisture, being the #1 enemy, causes wood rot, mildew, mold; paint blisters, and renders insulation to be ineffective. Moisture rises with the hot air and forms condensation inside your attic. When the condensation forms it begins to rot the wood. This introduces mold spores into the air, as well as damaging the wood. Trapped moisture causes damp insulation, mold/mildew, the moisture works down through the walls and causes paint to bubble, crack, and peel. Trapped moisture can cause serious structural damage to your home. Heat in unventilated attics may cause temperatures to exceed 150 degrees causing damage to roofing material, roof sheathing and possibly radiate to the living area. By ventilating, you are extending the life of your roof, insulation, and other building component, it also reduces energy bills, and eliminates mold/mildew which can lead to major health problems.
What is Ventilation?
Ventilation is simply the process of supplying a continuous supply of air through the attic space. “Proper ventilation” consists of 50% intake, under the eaves, and 50% exhaust, near or at the roof peak, at least 3 feet higher than the intake systems. Intake ventilators let fresh air in. Exhaust ventilators let heat and moisture out. A proper ventilation system gives you the best protection against heat and moisture. Several types of vents can be used to properly ventilate the roof of your home.
You must ventilate year around. If your roof isn’t getting the life expectancy it should, it could be due to improper ventilation. So protect your investment ventilate!
