If they are a darker color you may have to just hit them again. No big deal.

Like the Scorpions said...."Time, Give me time"  Just wait until Mother Nature gives it a good soak, then things should be fine!

Could need a touch up. I still use cider. Thinking about changing, no need to but, thinkin bout trying something new. With cider there is an occasional touch up. Could it be rust stains?

The roof was hot and it smoked off a little. Only happened to me one time and the rain washed it off just fine like any other.

no you dont want to pre rainse because your feeding the algae with good food(Water). you want it to feed it the bad stuff SH. its better if its dried out because it will soak up the chemical to the roots and thats a good thing.

 WE have found that wetting a rooftop slightly, helps manage the cleaning a little better (only when its really hot outside.).  We all know that the Shasta White shingles are the hardest to clean in that when finished often times after it dries there are brownish-blackish stains remaining.  To combat this we will treat a roof and then keep it damp longer than the sun will allow (often times with just water)  we also start off with a hotter mix on the shasta white

That's what Chris advises and I will from now on; you waste product when it evaporates and the soaps like it.
