Remove tile. Locate and mark center of raer.
Use a straight edge and measure up 6 " from
bottom of tiles to center of the mount over the
center of raer.
Align QBase over raer center and drill two "
pilot holes. Fill pilot holes with sealant compatible
with roofing material. Place grade-8 cap screw
under QBase in hex slot, threads pointing up. Lag
QBase into raer through pilot holes.
Install subflashing. Waterproof at underlayment level
according to roofing manufacturer instructions and
Tile Roofing Institute Guidelines.
With a diamond blade on a grinder or skill-saw, cut
tile to allow post to pass through. Place cut tile back
in position. Insert post and tighten into place.
Install the 18"x 18" flashing. Pre-bend the flashing
to follow the contour of the tile if curved. Apply
sealant where post and flashing meet, and install
EPDM counter flashing collar. Seal o the post from
weather exposure with the racking hardware in the
interim before racks are installed.
Another acceptable method is to notch the tile and
install the 18"x18" flashing under the tiles. This is very
common in standard roofing.
You are now ready for the rack of
your choice. Follow all the directions
of the rack manufacturer as well as
the module manufacturer.
All roofing manufacturers’ written
instructions must also be followed
by anyone modifying a roof system.
Please consult the roof manufactur-
er's specs and instructions prior to
touching the roof.
