Gable vents are on my house plans, but the stucco and stone are finished on the front of my house. ( I think the builder forgot them).Shouldn't the gable vents be installed prior to the stucco and stone being applied to the house? Builder said the are only for decoration. I thought they helped vent the attic. We do have other ventilation for the house and attic.My builder said the serve no other purpose but decoration....I disagree. I wanted them to help vent the attic in addition to the other ventilation. Wouldnt this also help my electrical bill. I live in Texas where it is hot.
