Benefits of Attic Ventilation:
Attic ventilation helps maintain a healthy, energy efficient home. It extends the life of your roofing shingles and underlayment and reduces moisture build up that can cause rot and mold. The amount of ventilation an attic needs is determined by many factors, but in general the more the ventilation your attic has, the better off you will be. As attic air turnover is increased, the attic temperature will begin to approach that of the ambient outside air temperature, which in turn minimizes heat transfer into your home. Attic venting can also reduce the load on your AC in the summer, which can save you money. In colder climates, it can help in preventing damaging ice damming. In addition to the reduction in your utility bill, a typical installation will usually pay for itself in savings within 1-3 summers of use.
