Replacement flashing for exhaust gas vents beneath roof-mounted photovoltaic systems

An exhaust vent replacement flashing for use with a roof mounted photovoltaic system comprising:

• a substantially flat flashing portion;
• and
• a raised interior portion protruding from the flashing portion so as to provide clearance for any residual flashing or roofing debris adjacent a section of exhaust gas vent pipe protruding through a roof surface and having an opening adapted to fit over and receive the section of exhaust gas vent pipe;
• and
• a collar or gasket for sealing the exhaust gas vent pipe to the flashing.

An assembly comprising:

• a generally planar shaped flashing plate having a raised interior portion that provides clearance for any residual flashing protruding from the roof and an integral housing for fitting over an existing rooftop sewer gas exhaust vent pipe;
• a flexible hose portion coupled to the sewer gas exhaust pipe;
• and
• a vent portion coupled to the flexible hose portion, having a top-facing opening that allows sewer gas emitted from the sewer gas exhaust pipe to exit into the atmosphere above a photovoltaic array via the flexible hose portion.
