What is the best way to ventilate an attic for energy efficiency?

Start with our 60–90 minute roof-and-attic inspection by our Lomanco certified ventilation experts to verify ventilation needs and attic access. Our experts provide clear calculations to document what the building code says is needed to ventilate your attic and ensure it is a balanced system. Vent bathroom fans to the outdoors, not into the attic. Use top-quality vent components and underlayment. Pair ventilation improvements with blown-in insulation to cut heat loss. Maintenance plans with regular inspections help keep vents clear and working. Ask about our 20% Instant Rebate on blown-in insulation (1,000 sq ft minimum; not combinable; expires 2025-10-30).
