Step 1 build the frame of the roof on the ground.
How to frame a deck roof.
Frame up a box the size of the outer dimensions of your deck using 2 by 4 inch lumber.
They are merely placed on top of another structure.
For a solid connection you ll have to make sure the frame has the appropriate blocking.
Place pier blocks so that the posts will be against the inside of the support frame.
These are used to attach the support posts to the frame of the deck.
If the posts supporting the roofs are placed directly on the deck structure below there are a few considerations to make.
These decks are often referred to as floating as they are not secured in place as a stand alone structure.
Building a deck over a flat roof is very similar to building a deck over a concrete patio.
Install post base connectors.
Then run joists connecting the front of your roof with the rear every two feet along the length of your roof.
Before you begin make sure you re matching the house roof pitch angle and overhang for your roof.
If you like the idea of having the roof above your house s roof you need to make sure the support posts are within 4 feet or so of the original gutter on that side.
The posts should stack directly above a support post below and not within the span of a beam.
