The water around my part of the world typically 50 to 60
PSI, at 2.2 feet lift per PSI. Which is plenty to get to the
top of a 20 foot roof. The one I did a couple weeks ago,
plenty of pressure at the roof.

Did you have a cheap vinyl hose with lots of kinks to cut
off the flow? Enquiring minds want to know!

Don't know if it's been mentioned...are you sure there is
sufficient
water pressure to get water up to that roof? Have a little
experience
with connecting outside faucet to use on second story, and
it wasn't
much pressure.
