We got a new roof about four ago. The attic is unfinished. It's a split level home, and hot as Hades upstairs.
Unfortunately, the roofers didn't consider attic ventilation. They installed a ridge vent, but the only intake is a gable vent near the peak of the roof. Now we realize that hot air stays at the bottom of the attic in that scenario. So we need to add ventilation at the bottom of the attic. Our soffits are not vented. Seems to me the options are to vent the soffits, or to add a shingle-over intake vent along the lower edge of the roof (then seal up the gable vent). Is either of these options preferable for a relatively new roof? We live in DC.
