Interiorly installable exterior surface mount

摘要

An exterior surface mount for mounting a member such as a vent or pipe on an inclined roof or a wall of a building in which the member extends through an opening in the wall or roof. The mounting is disposable on the exterior of the wall or roof wholly from within the building. The mount includes an upper support or flashing member having a peripheral flange with dimensions that are larger than the opening so the flashing member covers completely the opening. The opening has one dimension larger than the smallest dimension of the flashing so that the flashing member can be slipped through the opening from the inside of the building and fitted on the outside of the wall or roof. A member receiving aperture is disposed within the flashing and is arranged to receive the vent or pipe. Gasketing is provided to seal any spaces between the aperture and the exterior of the member. An interior mounting device, such as a flange with fasteners or clamps, is disposed within the building to secure the flashing to the interior of the wall or roof from within the building. A seal or gasket is disposed between the peripheral flange and the exterior and is compressible to prevent the flow of water into the interior of the building from the exterior surface.
