We have done a few roofs over the past week or so , we have been waiting for rain to come but it's only sprinkled alittle no heavy rain or even a nice steady rain. Will the roof come clean once it rains say 2 weeks from now or should we rinse?? What would be a good rule of thumb ?
Let it go. The rain will reactivate the surfactant (soap) that you used and will lift all the dead mold, algae and pollution from the Roof and will rinse it Clean.
i will trade you, have rain here for the next 2-3 days, have to put 10 roof jobs on hold.... be patient my friend , whats the roof look like that you cleaned?? the love is still there just in a neutral state....

my first roof I did sat there for 2wks before it actually got some rain. but wow it looks great now. here is what it looked like before, after, after rain two wks later.
Not sure why you guys have to worry about the rain rinsing the roof. Instances that you have visible dead algae should be veeery rare. 99% of the roofs we clean are 100% clean when we leave. Only ever so often do we have a situation where we need the rain to make it look better.
The only other instance is when we use too much soap and it leaves a dull film.
Moss puffs should be stringy and gushy with only a few real "puffs" left here and there that may take a while to come off. For the most part they should melt away
You can rinse them off but give it a week or 2. Let them release from the roots so you don't pull them off the shingles.
Here are 3 different pics of 3 different stages of moss decay.
