Ridge detail
There are four standard ridge cap profiles available; Apex, Barrel,
Deluxe and Standard. Depending upon the profile chosen the ridge
layout should reflect the drawings below (figure 1).
Barge detail
The turn-up edge should be 40mm, and the overlapping barge cover
should return down 30mm (minimum) to ensure a weather tight
joint, refer to figure 2.
Hip board
The hip board should protrude a minimum of 40mm past the rafter
to provide the necessary room to fix the turned-up tiles against the
hip board, refer to figure 3.
Fascia board
The fascia board should be set 40mm higher than the rafter, in line
with the last tile batten, refer to figure 4.
Valleys
Valley boards need to be fixed between the rafters to support the
valley gutter, refer to figure 5.

BATTEN INSTALLATION
General information
Batten moisture content, straightness and spacing are critical to the
appearance and functionality of the Suntile
TM
Classic system. Poor
layout can result in misaligned laps that do not seal effectively and
aesthetically diminish the appearance of the product. It is advised
to set out a marking device that provides the correct batten centres
to ensure accuracy.
Timber used for battens should be seasoned (moisture content
15% or lower) and kept dry. Excessive moisture content in wet or
unseasoned battens causes them to shrink after installation, and
may result in uneven tiles.
If stored on site, the battens should be placed on level bearers to
prevent contact with ground or water. They should also be covered,
if necessary, to keep them straight and dry.
Batten fastening
Simply load up the battens onto the roof, ensuring that all joints are
staggered, and nail one nail per intersection. Where a joint falls it
is necessary to nail both sides of the joint over the rafter (Refer to
NZS:3604 section 10.9 and 10.10).
