INSTALLATION
GUIDE
THE SUPERIOR ROOF TILE
TOOLS REQUIRED
You can be assured your Stratco Suntile™Classic roof will be strong and durable, because SuntileTM Classic roof tiles are made from high quality
coloured steel. When correctly installed, the interlocking tile panels deliver a weather tight barrier to protect your home against the elements.
Each SuntileTM Classic tile measures 1300 x 370mm which gives you design flexibility and ease of handling, resulting in quicker installation and
minimised transportation costs. The SuntileTM Classic tile is a light weight roofing solution, weighing only 3.5kg per m2, minimising the cost of
framework and making it suitable for situations where unstable ground exists.

BEFORE YOU START
It is the responsibility of the architect, builder and building contractors to ensure all material and works carried out comply with the relevant
standards, regulations, codes and by-laws. Carefully read these instructions before starting your project. Install SuntileTM Classic tile as outlined
in this brochure to ensure they achieve their optimum performance.
SuntileTM Classic tiles are recommended for installation on roofs with a pitch of 12 degrees or greater. A paper based underlay is required for
all roof pitches, as is outlined in the ‘New Zealand Building Code, Clause 2, External Moisture, 8.3.6’.

COMPONENTS
Figure 1
Figure 2
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 SuntileTM 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).

TILE INSTALLATION
Laying Direction
Prevailing Wind
Figure 8
General information
The SuntileTM Classic tile should always be installed with the overlaps
facing away from the prevailing wind. In addition, where possible
laps should also face away from direct sunlight.
Where possible installation should start at the ridge and work down
to the fascia, reducing the amount of traffic on the installed tiles.
Nailing and fastening requirements
Nail position, spacing and tension are critical to the appearance and
functionality of the SuntileTM Classic tile system. Incorrect fastening
can result in uneven tiles that aesthetically diminish the appearance
of the product.
Stratco recommend that a pneumatic nail gun is used to achieve
consistant tension and minimise the risk of damaging or scratching
the tiles. Round head 45mm or 50mm hot dip galvanised roofing
nails should be used to fasten the tiles to the roof battens.
Hold the tiles firmly against the batten and fasten in four positions
through the turned-down front edge of the tile as shown in figure 9.
The lowest course of tiles (the eaves tiles) should be fastened
through the top of the profile avoiding areas within the profile that
carry water.
Paint all nail heads using touch up paint to match the tile colour.
NOTE: For “high wind speed” (44m/s) and “very high wind speed”
(50m/s) local regulations for the region will apply. Generally this will
result in seven fastening points per tile for the top two and bottom
two tile courses and one tile in from hips, valleys and barges.

Gable roof
Starting with the second course from the ridge, lay the full course
of tiles from barge board to barge board ensuring the end tiles
have been turned up to create a weather seal. Next, complete the
ridge course by cutting and bending the tiles to suit the ridge board
and fasten in place. This reduces the foot traffic needed at later
stages. Continue laying the tiles two courses at a time working down
towards the fascia board. When laying a straight gable roof it is
recommended to start every second course of tiles with a half tile
which staggers the over-laps across the complete roof (figure 11).
Figure 12
Hip roof
Again starting with the second course from the ridge board, lay the
tiles in the desired direction (laps facing away from the prevailing
wind). This course must start 150mm from the hip board and finish
where the last full tile ends, refer to figure 12.
Continue this process down the roof laying two courses at a time.
Tiles that need to be cut should provide enough material to cut two
pieces from one.
Ridge section
The majority of ridge tiles will need to be cut and bent to suit the
rafter length. These dimensions can be obtained by measuring the
distance between the underlap of the last tile, to the ridge board
(this provides the bend line). Add 40mm to this dimension (this
provides the cut line) and cut the tile along this line (figure 3.5).
Turn a 40mm section up to suit the roof pitch and install the tile
ensuring the up-turned section is fastened to the ridge board.

Hip section
To prepare the first and last tile of a hip course, measure the tile
length from the last lapping pan across the face of the batten to
the hip board or hip batten (figure 15). This is done for the top and
bottom dimension and provides the folding line. 40mm must be
added, past the bend line to mark the cut line.
The cut tiles are installed from the bottom upwards, fastening into
the front of the tile (as standard) and also at two points along the
turned up edge. In many cases the off cut from one side should be
enough material to use for the other side, reducing the amount of
material waste.
Figure 15
Valleys section
The cut tiles required to complete a course that runs into a valley are
prepared by using the same procedure as the hip. The measurements
are taken from the last matching pan to a point in the valley gutter
which allows for a minimum of 50mm clearance between tiles, but
also has an overhang of at least 50mm in the valley gutter.
Fastening the tile should reflect the standard fastening points along
the face with additional points as close to the valley as possible
without damaging the surface of the valley gutter.
RIDGE AND FLASHING INSTALLATION
MAINTENANCE
The performance of SuntileTM Classic over time is dependant on the correct application of the product as outlined in this brochure, on correct
product selection, and on maintenance suitable for the environment in which the product is to perform. It is important that the nails have the
same life expectancies as the roof tiles.
SuntileTM Classic is produced from the highest quality materials and will provide many years of service. For more information on gaining the
best performance from your product, refer to the ‘Selection Use and Maintenance’ brochure.
Barge covers
Barge covers should overlap the metal tiles and cover the side of
the barge board by a minimum of 50mm. To ensure a weather tight
seal is formed it is critical that the edge of the tile is turned up by
40mm and fastened to the barge board.
Ridge and hip caps
There are several forms of ridge caps available, all of which have
been designed to work with the up-turned edge of the tile. All ridge
tiles must be bent up by 40mm and fastened to the ridge board.
Flashings
General flashings are used to ensure a weather tight seal is created
in non-standard areas. A flashing is the final cover over a particular
joint, and should not be the only means of creating the seal.
Underneath all flashings, the tiles should (where possible) be turned
up by 40mm for a weather tight finish, additional side flashings may
be required to complete the seal. Builders and building contractors
must ensure that all flashings comply with the relevant standards,
regulations, codes and by-laws.
