NOTICE: Failure to properly caulk the roof flashing and
pipe seams could permit entry of water.
• Caulk the gap between the roof flashing and the outside
diameter of the pipe.
• Caulk the perimeter of the flashing where it contacts the
roof surface. See Figure 7.13.
• Caulk the overlap seam of any exposed pipe sections
that are located above the roof line.
