Yes I was not rinsing the heavy infestation off earlier in the season and I found that I was not getting a complete kill of all the algae, so we decided to rinse it so we could treat again before we left .
Believe me it was very tempting to fire up a pressure washer, but that would not have been in the interests of our customer so we took 2.5 hours to rinse it gently...
small jobs lead to bigger leads so we put in the time to really make it look good in one day. This customer was very concerned about environmental impact and loved our 5 yr warranty.
I like that fact that even when we are dealing with lawyers we can dot the 'i's" and cross the t's to assure them we are the safe professional way to clean their homes.
Dramatic results give then something to talk about.
Hi Steve, great job! When you rinsed with the garden hose did you use a pistol type nozzle on straight stream?? If so, did you notice any granule loss?
I'm very curious because I often see moss and lichen build-up here in Richmond and am tempted to do the same. I've just been concerned about rinsing off what I'm trying to protect. I use that point to help sell my jobs. I usually explain to the customer that although the black streaks are gone and that the light tinge will be gone with the first heavy rain, the moss and lichens will take more time to get brittle and "weather-off".
Josh We are often dealing with this type of infestation because no one knows about roof cleaning here yet...
We plan to change that.
You should see some of the mess that Josh has to deal with! For some reason the lichen and algae is supercharge in his neck of the woods. Most of his roof more closely resemble cabbage patches than shingles when he shows up! I wish he would post some pics here!

I am concered about washing off as well. I have the same problem on the other side of Pa. Seems like the lichen are taking about a month to curl up and wash off. Once dead they resemble a bee hive texture. What I am finding is that, once they are washed off, there is already damage to the roof shingles. Here are some pictures.
This is what I see in VA too. Seems like the moss likes to take a "divot" out of the granules. Obviously moss has poor golf etiquette and never learned it should replace it's divots. HAHA
Ditto Guys I just found that if I did not gently rinse off the heaviest stuff, I was not getting a complete kill on our first jobsite visit. I like to know it is dead.
This garage roof is shot in the sense they neglected it for a long time and the critters ate a lot of granule holes. Lichen and moss are destroying roofs for sure.
I use that as a selling point when the gleocapsa magma is real heavy. I assure them it's 'kissing cousins' are there and will show up when we start spraying.
We chose to rinse so I could get to the rest of the growth and finish to job. The customers are lawyers and wanted full assurance that we would back it with our 5 year limited warranty, so I wanted to be sure we got a complete kill.
