    Abstract: A precipitation resistant ventilator for a structure enclosing an interior space. The ventilator encloses a space that is in communication with the structure interior space. A thin sheet of air permeable water resistant material is disposed within the ventilator interior. The thin sheet of air permeable water resistant material forms a barrier that excludes the entry of precipitation and other foreign matter into the roof structure while still allowing air exchange.
