How can I take down an awning?
That photo is not very helpful in identifying how the awning is attached to the house. In general, there should be brackets of some type, which grab hold of a metal rod that's within a pocket of the awning. Once you've figured out how to free the top of the awning from the house, you'll have to remove the ropes that tie the awning to the support structure. Once the cover is free, you can roll it, or fold it up. 

It shouldn't weigh too much, as it's just a sheet of canvas.  I usually take mine down, and put it up by myself. So if you're able bodied, you should have no problem. If you're not, you might want a hand getting it down.
