I can never get these areas as clean as I would like even with plenty of scrubbing and muscle behind it. The customers are happy and I know that thier happiness is the end goal, but if anyone knows of a product that might help me cut through these trouble spots to get a better result faster

Is that rust or Gold Mold???

IF that's mold and not rust, I'd hot water/low-pressure wash it, then treat it with green wash, then rinse with water, then final rinse with Bleach Wash, especially if it has exposed screws.
It almost looks like rust from a well irrigation system because it's on the front of the house and the stones... but then again, it's on the ridge cap. That's weird.

It's pollen and fallout from live oak trees

I recently had one that was a bit worse than what you have there. It had Oak tree sap on it that had been sun dried for years (but mine was black). I did exactly what I suggested above and it came out great.
Good luck with it!

Was soft wash used on this roof?

The picture shown is the before picture. I did use soft wash on this roof. To Paul or anyone for that matter. Wouldn't you be afraid that hot water might warp or damage the metal on the roof or discolor painted metal roofs?

I only use as much heat and water pressure as necessary to get the bio-matter off. I've never had a problem
