perhaps you can I'm not so sure on that question sorry.
To calculate the roof surface area needed to fill a 30,000-gallon tank with one inch of rainfall, you will need to know the collection efficiency of your roof. A common value is around 90%. With that efficiency, you would need a roof surface area of approximately 6,667 square feet to collect enough water to fill the tank from a one-inch rainfall.
I was searching that video too and found it by mistake I hope it was the same one Weapon Of Choice - Fatboy Slim

The roof of a fixed roof tank assists in keeping the shell rigid and wind forces are transmitted to the bottom of the tank.Open top or external floating roof tank do not have the benefit of this shell rigidity and therefore a circumferential wind girder is provided at or near the top of the shell to give it necessary stiffness. This girder is normally attached to the external surface of the shell and in many cases also used as an access and maintenance platform.You may refer Guied of storage tank and equipment by Bob Long and Bob Garner.
