Abstract
Various roof vent adaptors are disclosed. The roof vent adaptors can be used to seal penetrations on buildings, such as vent penetrations on metal or non-metal roofs. In various embodiments, the roof vent adaptor includes a sealing member, an outer securing unit and an inner securing unit. The roof vent adaptor can be secured to the roof to provide a generally liquid-tight seal around the roof vent, thereby inhibiting or preventing water intrusion into the building.
