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 three feet higher than the intake system.

Why Ventilate? To fight the enemies of heat and moisture, you must ventilate year round. Heat in unventilated attics may cause temperatures to exceed 150 degrees causing damage to shingles, roof sheathing and possibly radiating to the living area. Moisture being the #1enemy, causes rot, mildrew, mold, paint blisters, and renders insulation to be ineffective. Proper Ventilation: Reduces energy bills Reduces ice build up Eliminates mold/mildew which can lead to major health problems
