I replaced my slide awnings last year. It can be done by one person and a step ladder but it goes much easier with two people and some scaffolding running the length of the slide.
If you bought from Tough Top, call them up. Tough Top was very willing to answer all of my questions.
As you will see in the video, the new material is installed with the slide extended and the roller drum under tension. You need to pin the ends of the roller because you can't hold the roller and install the fabric at the same time.
