One of my really good customers is a historic Church in Apalachicola, which is about 2 hours drive from my house. This organization & its members is responsible for THOUSANDS of dollars in business to me annually, so when they call, I jump.
Church just bought this residential home and turned it into the church office. I had a very short window to do this job and it was raining on the day I made it to Apalachicola. Not very convenient to pack up and return another day after an investment of time, fuel and labor, so I decided to try out cleaning anyway.
I was delighted with the results of the cleaning, it did just fine with wet shingles. I waited until the eaves line quite steadily dripping rain water, then would spray, then a short downpour would come and I would stop and I'd wait a little longer and pick up where I left.
Process took much longer (2 hours) due to stopping and starting. Used a 40% SH mix and one gallon of Green Wash. Used 60 gallons of solution total ( made 75 gallons, thinned the leftover down to 15% and softwashed the house).
Roof was sprayed twice to provide these results. I'm just happy to know roof cleaning on a rainy day is now an option.
One thing I did notice is that the hotter mix with Green Wash ERADICATED the lichen, it simply rinsed off with the hose.
Ray Thank you for sharing real world results. I am happy to know that Green Wash gave such results on a less than ideal day. Now, will it work thru snow????
I've always shied away from cleaning wet/damp roofs but after experiencing these results, I will not be so hesitant to wash roofs in the early morning that are still wet with dew or on misty days. Would I try to clean one in a downpour? No, but my trip to apalachicola was unique due to the travel time involved and a very hectic schedule. Didn't have the option to postpone that job, since SPray Wash is booked up about a month in advance right now.

I actually pre-wet both Roofs and siding in the hot summer South Carolina months. It helps to cool the surface so the Cleaning mixture does not evaporate so fast.
I've washed plenty of damp roofs before and have even wet a few down in the summer time, but I have always stayed away from wet "heavy morning dew" or worse type roofs. This roof was a "soaking wet just after a drenching rain " kind of wet with more showers and sprinkles during the wash process.
On the wet roofs I have personally always found my cleanings to be spotty and streaky and requiring more SH than I like to use and with lots of touch-ups.
Seems to me like the GW alleviated those problems in this instance.

I have cleaned in the rain quite a few times. I still try to avoid it if I can. It takes a lot longer and we end up using a lot more chemical. Unfortunately, most times we can't help cleaning in the rain because it can really screw up the schedule if we don't.
We cleaned quite a few this year with heavy frost on the northern side of the roof. A few even had leftover snow on them. I used our truck wash brushes on long extension polls to pull the heavy stuff off the roof and then sprayed away. It definitely took longer and I used a little more cleaner, but we still got the results we needed.

40% sh...............Is this a 4% strength?

Laurie... That is correct, my 40% essentially equals 4% on the mixology tables. I had been doing this type of calculation for years before subscribing to the Softwash systems manner of calculations. ACs methods are better and more accurate for measuring, but old habits die hard, so many times I revert back to the old way of calculating when posting my ratios.
