STEP 1 – LAYOUT
All pergola kits are fabricated to
fit the size ordered. They CAN
be trimmed to fit a smaller space
if necessary.

a)
Determine necessary height
and post locations based
upon site – Make note of the
following measurements as
you will want these later:
a.
Desired outside to outside
dimensions of your posts
b.
Desired height to the
top of your beam
c.
Desired direction of shade
purlins and rafters
d.
If you desire to trim the
width of your pergola simply
determine your ideal size
and build accordingly. You
can very easily mount posts
and trim the appropriate
beams and purlins as you
follow the installation steps.
e.
IMPORTANT -
If you desire
to trim the depth of your
pergola you must take into
consideration the purlin
holders. To avoid having a
"half hole" in your roof you
should first remove the purlin
holder and determine what
trim length will allow you
to cut between the holes.
This same measurement
can be then applied to your
post mount spacing. You
will trim each beam, rafter
and purlin holder in your
kit by this exact size as you
follow the installation steps.
b)
IMPORTANT -
Ensure posts are
SQUARE with each other and/
or any adjoining structure –
NOTE:
If adding to an existing
slab or patio do not assume that
they are built square! The best
way to determine if things are
square is to measure diagonally
from post base to post base
and adjust until the diagonal
measurements are the same. A
square post layout will reduce
installation time and ensure
an excellent fit and finish.
c)
It is common that existing
concrete and paver patios are
installed with a certain degree
of slope. If slope is minimal
(less than 1" in 10’) you can
simply disregard it. If slope is
more pronounced, consider
that your posts may be differing
lengths to allow pergola
roof to be level to horizon.

fabrication of pergolas to
your unique site is available,
