    2. Wrap the Retrofit around the pipe and install all snap rivets to seal the flange.
    3. Press the Masterflash® down, bending it to conform to the roof profile or roof irregularities. A blunt tool will help press the flashing into tight roof angles.
    4. Apply a silicone selant between the Masterflash® base & the roof.
    5. Use fasteners to complete sealing. For UPC installation, fastener spacing may not exceed 1½".
    6. Apply sealant to any gaps.
