  • Why do you need to ventilate your home?

Proper ventilation is required to protect your home.

Heat in unventilated attics may cause temperatures to exceed 150 degrees—causing damage to shingles and roof sheathing, and possibly radiating to the living area. Moisture, the #1 enemy, causes rot, mildew, mold, paint blisters, and renders insulation to be ineffective. Proper ventilation reduces energy bills, winter ice build up, and eliminates mold/mildew, which can lead to major health problems.

A proper ventilation system with Lomanco® Vents will extend the life of shingles, insulation, and other building components.
