NOTE:
Remove any Tek screws along this sidewall
edge if needed and reinstall these through the flashing
and into the sidewall hat channel. The flashing must fit
flush against the polycarbonate sidewall panels.
Do not
overtighten the Tek screws
.
2. Attach the flashing to the sidewall hat channel.
3. Cut another section and install to finish the corner joint.
Overlap the top of the first section by a few inches.
5. Take another section of flashing and install it along the
roof edge of the end wall. Flashing is shown placed on
top of the roof panel. Secure the edge with Tek screws
and washers driven into the hat channel of the roof.
INSTALL THE ROOF FLASHING (continued)
Complete these steps to install the flashing:
1. Measure and cut the first section of 106513 flashing to
install along the edge of the upper sidewall panel. See
the arrow in the diagram below.
4. Move to the other corner of the first end wall and repeat
Steps 1-3 to install that flashing.
ATTENTION:
Do not install Tek screws and washers
through the 4" flashing surface that overlaps the top
edge of the end wall panels.
This 4" surface of the flashing will not sit flush against
the end wall panels due to the mounting screws and
washers that secure the panels to the end rafter. When
installed correctly, a small gap will remain between the
flashing and the end panel.
Do not install screws though the flashing and into the
end rafter. Doing so will result in an uneven installation
and appearance.
6. Using additional sections of flashing, continue working
along the roof edge, up and over the peak, and down
to the point where the corner flashing meets the roof
panel.
NOTE:
Overlap the different flashing sections and cut
slits in the flashing to allow it to bend over the peak of
the rafter as needed.
Install the flashing
under the ridge cap
. When you
reach that point, remove any Tek screws that secure
the ridge cap to the hat channel, slide the flashing
under the ridge cap and reinstall the Tek screws. If no
screws are at the ends of the ridge cap, install screws
through the ridge cap and flashing to secure the ridge
cap at each end.
7. Continue by applying the silicone to seal seams and
panels.
