I replaced my Zipdee awning material myself. I used material from Stone Voss in brooksville, Florida- friendly people and good quality product. Mine is also the topper that extends into an awning as well. I found it a bit challenging but definitely doable if you are handy. You will need 2 people for the longer toppers. I have a 14’ and 8’ slide.
There is probably a manual for your awnings online somewhere- I found one for mine.
