Attic Ventilation in Lansing, MI
A roof needs to breathe. Balanced attic ventilation keeps the deck cold in winter and stops summer heat from cooking shingles and upstairs rooms.
Request a rooferIntake and exhaust
Air should enter low at the soffits and leave high at the ridge or roof vents. Blocked soffits or too few exhaust vents leave the attic stale.
Winter frost
On cold nights, warm, moist air from the house can freeze on nails and the underside of the deck. When it melts, it drips onto insulation and ceilings.
Air sealing first
Gaps around light fixtures, attic hatches, plumbing stacks and chimneys let house air into the attic. Sealing them reduces frost and ice dams.
Bath and kitchen fans
Fans should vent outside, not into the attic. A fan blowing into insulation adds moisture right where it causes damage.
Summer heat
A hot attic warms upstairs rooms and ages shingles faster. Good ventilation lowers attic temperatures on humid summer afternoons.
Don't mix vent types
Combining a ridge vent with gable or powered vents can short-circuit airflow. A roofer can set up a balanced system.
