A NOTE ON
PERGOLA SIZES
Sizes are defined by the total
width and depth of the roof. For
example, a 12' x 16' pergola will
have a roof area of 12' x 16' and
a post spacing of 10' x 14'.
ALL PERGOLA
KITS CAN BE
CUT TO SIZE.
The beams and rafters supplied
in the kit are NOT pre-drilled. This
is to allow the width and depth to
be customizable for each kit. Our
standard sizes are designed around
a 1' overhang on each end. This is
merely a rule of thumb and can
be adjusted during installation.

MEASURE
a.
Determine necessary height,
post locations and overhangs
based upon site – Make note of
the following measurements
as you will want these later:
1.
Desired outside to outside
dimensions of your posts
2.
Desired height to the top of
your beam (same as height
to bottom of your rafter)
b.
Ensure posts are square
with each other and/or
any adjoining structure
1.
Post and beam spacing is
adjustable to fit installation
site and any obstructions.
Beam and rafter overhangs
should not exceed 36", purlins
should not exceed 24".
2.
NOTE: If adding to existing
slab or patio do not assume
that they are built square!

EXAMPLE:
If you have a patio that is 10'-6"
deep x 13' wide you would want
a roof that was at least 12'-6"
deep x 15' wide. You would order
the next size up, a 14' deep x 16'
wide and trim the beams and
rafters to your desired overhang.
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.
d.
Maximum span of 2x6 beams
and rafters is 16'. 2x8 beams
and rafters can span 22'
e.
Note that purlin holders do
not have to run under any
roof overhangs on your site.
This allows maximum head
clearance for your rafters.
f.
For challenging sites, custom
fabrication of pergolas to
your unique site is available,
please contact [us].
