Wow,
1.5 gallons for that large of a roof, it does not go on very thick. I would want something thicker, and I guess you have several coats by now. It is more labor to put on several thin coats than one really thick coat, as most the time is in the prep and washing the roof surface than application. I might suggest applying twice as thick (or 3 times) using 3-5 gallons. Then hopefully it will last for several years before needing to re-apply. That will save overall labor. . .
Good luck!
