b) Cut triangular gable infill panels (from the rectangular
panel provided ), to fit the vertical gable frames located at
each end of the Dutch gable roof. Paint the panels to the
desired colour before installing. Rest the panels on the
weather strip flashing. Fasten panels onto adjoining rafters
through the top groove using 12 x 35 roofing screws spaced
at 1000 mm centres.
c) Hip Capping: Attach the small lengths hip capping to
cover hip rafter seams, and mitre to fit the gutter corner.
d) Front and Rear Barges: The front and rear barge caps
are fixed to the crest of the CGI roof and front of the gable
infill panel. Mitre flashing to overlap weather strip and hip
cap so as to give a neat water tight finish at the Dutch gable
junction. Silicone joint if necessary.
e) If ordered, fix decorative strips to dutch gable infill panel.
f) Gable Spires (Finials): If decorative gable spires are
desired, nail the spire bracket to the back of the wooden
spire, and rivet in position at the top of the ridge.
g) Ridge Cap: The ridge flashing can now be attached. The
ridge should finish flush with the end of the carport,
overlapping the front and rear barge capping to provide a
weather proof seal.

FIX FLASHINGS AND INFILL PANELS
Refer to Figure 20 for all flashing positions. In general
fasten all flashings using 3 mm pop rivets at approximately
600 mm centres. However when fixing flashings to the infill
panels use split-tail rivets.
a) Dutch Gable Weather Strip: Position flashing along collar
tie member with leading edge resting on top of roof sheets.
Notch flashing to fit around gable rafters and fasten with
pop rivets.

ROOF SHEETING
Begin sheeting the internal framework of the carport roof
with the large CGI sheets, allowing for a 40 mm overhang at
the eaves into the gutter (see Figure 19). Always have the
lap joint facing away from the prevailing wind direction on all
carport roof faces. Lap final sheet to fit last span. Position,
mark and cut triangular sheets for sides of Dutch gable roof
section.
triangle offcuts are re-used on the opposite side of
roof, so make sure the cuts are clean and accurate. Make
sure offcuts are positioned correctly before laying the
longer sheets, so that capping direction can be determined.
Crest fix CGI sheeting with 12 x 35 Roofing Screws using 5
per sheet for end spans and 3 per sheet for internal spans.
Work from one side of the structure to the other, marking
and cutting triangular sheets as appropriate. Pan fix the
triangular sheets to the hip rafter with 10 x 16 hex head self
drilling screws.
Sheet the front and rear faces of the Dutch gable roof.
Crest fix the sheets and triangular offcuts at the end rafter
and front purlin locations. Pan fix with 10 x 16 hex head self
drilling screws at collar tie and hip rafter locations.
Attach the gutter straps at 1200 mm centres by crest-fixing
to roof sheets with 10 x 16 Screws. Construct two 85 mm
downpipe offsets from the downpipe lengths supplied and
attach to pops with rivets. Fasten the downpipes and straps
to the adjoining column.
