I don't have any overhang. Can I use roof louvers or roof pots near the bottom of the roofline?

A roof louver (they are also called roof pots or can vents) placed low on the roof can lead to weather infiltration because the roof louver is not designed to be an intake vent. As water flows down the roofline air is coming into the roof louver. This can result in water entering the vent. In situations where there isn't an overhang, Air Vent recommends using The Edge™ Vent or ProFlow Vented Drip Edge—both of which have been designed for homes with little or zero overhang.
