For most residential single family homes the Soffit area is the main source of intake ventilation for the roof / attic space. Older homes used plywood for soffit material that often had very few vent holes. To improve the intake ventilation in the attic we can cut new vent holes and cover them with milled aluminum soffit vents. This allows for more air intake and hence better air circulation in the attic.
