small repair works at home

My EPDM roof must have a big section cut out to repair water damage (a leak around ac that only showed up recently, must have leaked for some time). I am looking for suggestions as to what liquid roof product to use to do the entire roof over the existing rubber roof as well as the exposed plywood from the repair. I’m leaning toward a system called roof repair burke va but would love to find what others have used with success.
