  • 2Remove shingles surrounding the vent with a pry bar to avoid damage.
  • Pry up existing flashing with the use of a lever.
  • Gently pull flashing to remove over the vent pipe.
  • Replace with new flashing by aligning the collar in the same direction.
  • Use roofing nails to secure flashing around the perimeter of the vent pipe.
  • Cover exposed nail heads with asphalt cement; apply cement around the perimeter of the collar to seal.
  • Replace removed shingles evenly, working from the bottom row up.
