Have you finished this project? It actually sounds like a really great idea, however the plans that you are having are quite... unrealistic. Back when I started a similar project with my dad, we were really dissapointed, as our calculations were really... bad and messed up. We also though that a $100 1.6 hp motor would actually have enough power for this, however it was just some wasted money. Thankfully, we have actually done it recently, with the help of the guys from https://city2surfroofing.com.au/roof-repairs-sydney/. They are probably the best in roof repairs and many other things.
