Size and location of all roof penetrations should be an important consideration. Areas around roof vents or rooftop units may
show that corrosive fumes are emmitted from a process within the building.
NOTE: The following procedures are for vent pipes 6" or less and not transmitting extremely hot or caustic
materials. When installing vent pipes abide by the local plumbing codes.
1. Determine the size and length of the vent pipe to be raised.
2. Take the appropriate measurements for the vent location and mark them on the Magna-Loc panel. The vent pipe must
extend through the flat of the roof panel. If the vent pipe extension cannot be raised directly into the flat of the new roof
panel, elbows should be used to offset the pipe. Cut the panel to fit the vent pipe properly.
3. Use a light gauge angle to secure and plumb the vent pipe to the framing system.
4. Flash the vent pipe with a Rubber Roof Jack or similar pipe flashing.
5. Apply Tube Sealant between the panel and the base of the Rubber Roof Jack as well as the top where the boot meets the
pipe.
6. Attach the base of the Rubber Roof Jack to the panel using
