Steps on How to Build a Backyard Custom Built Pergola
Building a custom built pergola can be a
simple to challenging building project depending on what plan you pick so make
sure you know your skill level before starting. All the free pergola plans
include building instructions, lists of tools and materials that you'll need,
diagrams, and photos.
Steps
for Custom Built Pergola
1.
Measure the existing deck and sketch out a design for the project. The new deck posts and roof frame can support a traditional roof,
pergola beams or a louvered roof system. If using a louvered system, determine
the finished size of the louvered panels before starting to make sure
everything fits properly.
2.
Use a prybar to remove the deck panels from the posts being replaced. Use a reciprocating saw to cut through nails as needed. Don't cut
through the panels — they'll be reused with the new posts. Remove everything
attached to the posts, including any benches or swings. Use a prybar to remove
the necessary posts from the deck. To prevent injury, use a hammer to bend down
any nails sticking out of the posts before setting them aside.
3.
Measure and cut the new posts that will support the roof structure. Measure the notches in the old posts and mark the notch lines on
the new posts. Use a circular saw to start the cuts for the notches, then
follow up with a reciprocating saw to create clean inside corners. Use a miter
saw to angle the top of the new posts to match the style of the old posts of
your custom built pergola.
4.
Have a helper hold the new post in position and drill two holes through the
post and into the deck frame. Drive lag bolts
through the holes, tightening with a socket wrench. Tighten or loosen the bolts
as needed to keep the post plumb.
5.
Measure and cut a center post to help support the roof frame; the post should
be long enough to sit flush with the bottom of the floor joist under the deck.
Use a spade bit to drill a hole in the deck next to the floor joist; enlarge the hole so the post will fit snugly. Slip the post through
the hole, line it up with the bottom of the joist and attach to the joist. Make
sure the post is plumb and tighten the bolts with a socket wrench.
6.
Measure and cut 2-by-8-inch cedar lumber to frame the outside of the posts,
plus a pair of 2x8s to go between the center posts.
The louvered panels will fit snugly inside these frames. Tip: Use a jigsaw to
cut a decorative edge on the ends of the long beams and attach the beams to the
tops of the posts with lag bolts of your custom built pergola.
7.
Use long, galvanized screws to reattach the deck panels and any benches or
other accessories that were removed for the project.
8.
The posts and frame are now ready for a the roof treatment.
