Should I DIY my failing awning?

[Erin Caldwell]

We have an awning on one of our rental properties that seems to be trending downward. I first noticed it when we purchased the property 6 months ago and am now finally getting around to fixing it. Trust me it was not the first thing that needed to be fixed!

Over the last 6 month the awning has not sunken any lower but it is still concerning as you can see it starting to separate from the house (see pictures). Structurally it looks as it should have some sort of additional support.

My question is as a semi-experienced rehab and DIYer would this be something you would suggest tackling myself, and if so what suggestions would you have for fixing it? Or is this something I should consult a professional about?

One issue I have found is that if I wanted to put a support beam under it the area I would want to put a support beam would go in the soil of the bush and not on top of concrete

Any advice would be appreciated, especially if you have dealt with something similar.
