Soffit vents are one of the simplest parts of a roof system, and one of the easiest to overlook. They sit under the roof's eaves, in the soffit, and their job is to draw fresh air up into the attic.
Soffit vents draw fresh air into the attic to work with ridge or roof vents, keeping air moving and helping insulation perform as intended. Cooler air enters low through the soffit, moves up through the attic space, and exits high through a ridge or roof vent. That continuous flow is what keeps an attic from turning into a stagnant pocket of heat and moisture.
When that airflow path is blocked, whether by insulation packed too tightly against the eaves, debris, or vents that were never properly sized, the attic can't breathe the way it was designed to. That undercuts the performance of whatever insulation is up there, no matter how much of it exists.
Ventilation and insulation are a package deal. Adding insulation without checking that soffit and ridge vents are clear and working together is only half the job. Indy Roof & Restoration builds ventilation checks into its approach to attic work, correcting ventilation issues rather than insulating over them.
