Abstract
A roof vent is provide. The roof vent comprises a top component coupled to a bottom component. The top component has a top wall, a side wall, a first louvered region disposed between said top wall and said side wall, and a top cylindrical baffle located inwardly of said first louvered region. The bottom component has at least a first cylindrical collar sized and shaped for mounting to a cylindrical exhaust stack of a first diameter, a second louvered region, and a bottom cylindrical baffle located below and inwardly of the top cylindrical baffle. The first louvered and second louvered regions are for helping to prevent insects, and moisture, such as snow and rain, from entering the roof vent. The top component may also be used separately from the bottom component to cover over aging or aesthetically unpleasing passive pot vents.
