Roofing ventilation is not a factor many homeowners consider when thinking about conserving energy or protecting their home from weather damage, but proper ventilation can be vital for maintaining your home. Your home’s specific needs vary based on your location and the severe weather that affects you.
Roofing, or attic ventilation, has been shown to reduce attic temperatures in hot climates. This can help to increase your home’s energy efficiency and reduce cooling bills.
In winter, moist, warm air can collect in your attic. If not properly ventilated, this can lead to a variety of problems. Condensation can collect on the roof’s sheathing, which can then rot. Ice dams are also more likely when an excess of hot air in the attic melts snow on the roof from underneath, which then refreezes on the roof’s cooler perimeter. Condensation can also lead to rusting and mildew, which can cause both health problems and damage to your home.
Types of Ventilation
Ventilation can be passive or powered. Passive ventilation is most common, and relies on properties of air convection in which hot air is “pulled” upward. Powered ventilation may be necessary depending on the structure and location of your home.
Venting is not always appropriate. Attic spaces which are insulated and conditioned may not need any ventilation. Consult a home improvement specialist to determine if ventilation is necessary for your home, and which type is best.
