In order to fight heat and moisture, homes in all climates must be ventilated year-round.
Heat in unventilated attics may cause temperatures to exceed 150 degrees. It can damage shingles, roof sheathing, and radiate down into the living area. Moisture is a home's No. 1 enemy. It can cause rot, mildew, mold, paint blister and ineffective insulation. Proper ventilation reduces energy bills, winter ice buildup, and eliminates mold and mildew, which can lead to major health problems. Ventilating the attic space extends the life of shingles, insulation and other building components.
