Sound like you need a 32 foot ladder.
Yes, you could spray using a tip extension, a 6 foot long pole that attaches to the spray gun and holds the spray tip for reaching higher areas. If you do this you will still need to reach the trim, fascia board, with a brush or small roller.
Renting and using a sprayer is a possibility but you could also rent a taller ladder for a day. The ladder will be cheaper.
