CHIMNEY INSTALLATION
Details are subject to change without prior notice.
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.
FOR PENETRATION THROUGH THE SIDELAP:
When a penetration occurs through or near the panel sidelap,
install tube caulk filling the female overlap to 12” above the
penetration and snap lock groove to 6” above to prevent
water from running downhill into the opening.
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 penetration 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.
