ATTACHING END RAFTER EXTRUSION

Apply foil tape to the top of the end rafter, allowing it to over-lap the top edge of
the P.C.S.S. endwall covering. This prevents moisture, caused by condensation
from collecting between the two layers of the P.C.S.S. covering. (See photo #1)
Note: Before attaching the end rafter extrusion, be sure the ends of the ridge
base extrusion are covered with foil tape.

Starting at the top, lay the end rafter extrusion over the flange of the
ridge base extrusion making sure that the lip is turned down lapping
the P.C.S.S. endwall covering. Butt the end rafter extrusion up to
ridge base extrusion and insert two screws into the end rafter
extrusion, through the flange of the ridge base extrusion as shown
in photo #2. (Also see Fig. F)
Note: The groove under the end rafter extrusion is not large enough
to except the tek screw in the ridge base flange as was with the
intermediate rafter extrusion.

Working your way down, conform the extrusion to the shape of the
rafter, while inserting two tek-screws 12 to 16 inches apart down
the full length of the rafter. (See photo #3)
Cut off the excess, making sure that the end rafter extrusion stops
flush with the edge of the eave extrusion. (See photo #4)
