CHIMNEY INSTALLATION
CHIMNEY FLASHING - SIDE
FLASHING - VENT
Procedures:
1. Trim the opening in the flashing to 20% smaller than
the pipe diameter.
2. Slide the flashing down over the pipe.
3. Seal between the flashing and the roofing with
tube caulk and set the flashing.
4. Form the flashing to fit the profile of the roof.
5. Fasten the flashing with woodgrip screws 1” on centers.
NOTE: Alternate trim profiles are acceptable using the
screw pattern shown.
NOTE: In many cases it may be easier to locate
vent/pipe flashing in the flat area of the roof panel
(as shown) rather than have the penetration occur
at a panel rib. Determining panel layout prior to
installation often simplifies flashing installation.
1. Trim and bend the right side flashing as indicated.
2. Trim the left side in a similar fashion.
NOTE: Alternate trim profiles are acceptable using the
screw pattern shown.
NOTE: The left and right side flashing are mirror
images of each other.
