ABSTRACT:
A roof mount for supporting a vertically disposed tubular member on an inclined roof of a building in which the tubular member extends through an opening in the roof. The mounting is disposable on the exterior of the roof wholly from within the building. The mount includes an upper flashing having a peripheral flange with dimensions that are larger than the opening so the upper flashing covers completely the opening. The upper flashing can be slipped through the opening from the inside of the building and fitted on the outside of the roof. A tubular member receiving aperture is disposed within the upper flashing and is arranged to receive the tubular member. Gasketing is provided to seal any spaces between the aperture and the exterior of the tubular member. A lower flange having a central opening to receive the tubular member is disposed within the building and to engage the interior of the roof. Fasteners are sued to fasten the peripheral flange to the lower flange and are tightenable from the interior of the building to clamp the peripheral flange against the roof. The fasteners can include a plurality of bolts attached to the roof engaging side of the peripheral flange and extend into the building through the roof. A nut is attached to each bolt and the bolts are arranged to extend through holes in the lower flange. The nuts engage the lower flange to tighten the roof mount on the roof. A gasketing is disposed between the peripheral flange and the roof and is compressible to prevent the flow of water into the interior of the building from the roof.
