Use the steps below to
make sure that you order the right pergola for your project.
Know the Parts. The industry cannot even agree on
the difference between pergolas, arbors, and trellises let alone the
parts, so we need to first make sure we are talking about the same
things. Backyard America uses the following terms:
Attached or Freestanding? Will the rafters be attached
to a wall of your house or other structure? If so, you will need to order
an attached pergola. Freestanding pergolas require additional beams,
pergola ends, and hardware, which are included in the charge for the freestanding
option. The needed extra columns are included in the Dogwood model with this
option as well.
What Size Pergola? We specify the size of our
pergolas by their overall dimensions. The width is typically from one
end of the beam to the other end including the pergola ends. The
projection, or depth, is the length of the rafters including the pergola
end or in the case of a freestanding model, the pergola ends. Beam
pergola ends are approximately 12" and rafter pergola ends are
approximately 9". For the fiberglass Williamsburg model, the
pergola ends are approximately 12" for both beams and rafters. When stringers are ordered they are the same
length as the beam for the Potomac and about 2' shorter than the beam
with the Dogwood..
Do You Need Stringers? Stringers are added for
appearance, additional strength, and additional shade. Stringers with a 3" space
provide a minimum of 33% shade when the sun is above it. For additional
shade consider
retractable canopies.
Which Support Columns? The Dogwood prices include 5
x 5 vinyl square columns. For the Potomac, we offer round columns and
square columns. The size of the column is largely an aesthetic choice - what you
think is right is right. A column that is similar in size to the beam is
one rule of thumb that is used. We think that our pergolas look best
with columns that are between 5" and 10" wide.
How Will the Columns be Attached?
We provide post mounts and our very own TensionRod mounting system for
our columns. For installations on decks or other
elevated structures it is important to make sure that the columns are
securely fastened to the framing of the structure. Always use bolts and
screws and avoid nails for the attachment.
How about Lighting or Other Accessories? We
strongly encourage you to consider adding lighting to your pergola. It
will add greatly to your enjoyment and usability. An advantage of adding
lighting when installing the pergola is that you can more easily hide the
wires. Low voltage lighting for pergolas can be seen by

also want to consider a
ceiling fan as well to create a refreshing breeze.
