I have your roof tile on my home and am in the process of installing a propane unit heater in my shop. What is the best way to run my 5″ b vent pipe through the tile?
Any vent pipes through the roof require two flashings to be installed, one worked in shingle fashion with the underlayment and the other with the tile. The flashings should be properly lapped and sealed to prevent water intrusion and the the tiles may be temporarily removed and cut accordingly to allow for the pipe.
