A pro's take on attic ventilation

A tip to properly exhaust hot air

Q: My house currently has a continuous ridge vent in the attic and two gable vents (one on each end of the attic). However, it has no soffit vents at all. I’d like to install some but I’m not sure what kind are best. Is it bad to have more ventilation at the eaves than at the ridge? Any tips are appreciated. –Mike
