How can I extend a deck post on an existing deck?

Question

I have an existing deck (built in 1991) that I am making repairs to. As part of the work I want to extend the deck cover that's already there.

Existing deck

Desired outcome

So I know I need to either "extend" or put in new posts. Ideally, I would just replace the post with a longer one by attaching it to the the post anchor (as explained here).

However, the posts are embedded in the footing:

and have been cut off at deck height:

I'm looking for recommendations of how I would support the extended deck cover with posts? How would I attach them to the deck I currently have?

Answer 1

They make a metal brack to span the old 2X4 and you most likely can get it to work for the new roof. If not I can most likely get some made at work. You do have some good bracing and support on the one footing you have pictured here and if the other one is the same way it would be just as strong.

I would just pull out the old footings and replace them with the new style footing and be done with it.

Reasons: 1) you would always have questions as to how strong the modified brackets (ie the roof/posts are) and 2) By replaceing the old footing /posts you now have done the job and will pass and inspector.
