6.5 PREPARINg TILE ROOF INSTALLATION
1. Locate roof rafters or trusses.
Tip: here are 3 options to finding the locations.
A. Locate and measure the locations of the rafters
in the attic or at the outside eave and transfer
measurements to the roof.
B. Use a rubber or leather mallet to tap the roof and
locate the rafters. This will work with a cap sheet
or composition roof.
C. Remove a few tiles and scan the roof with a high
sensitivity stud finder.
2. Once the rafters have been located, snap a chalk line
on every rafter to identify the location.
3. Measure up from the eave 16" (400 mm) in at least
3 locations. Snap a chalk line. This marks the location
of the bottom edge of the front cover.
Note: This line needs to be 8" away from the next row
up front edge of tiles. The bottom rail (eave) should
be centered in the 2

Watt modules, install the next rails 4 courses higher
than previous rail.
4. Measure up from chalk line 1" and snap a new chalk
line. This marks the location of the bottom edges of
the modules.
5. Measure up from the module chalk line to the desired
module length to form the array. Snap horizontal lines
at the measured locations.
6. Mark and layout solar module vertical lines.
Note: modules should not fall in shaded areas.
7. Tile attachment is designed for use with a minimum
thickness of 15/32" roof deck and minimum rafter size
of 2" x 4".
8. Tile attachment is designed for use with flat concrete
tile, low profile S tile, and medium profile S tile.
9. The roof tiles must be able to fit within the 4 inch gap
between the deck and the rail.
