Hello all....so the last 3 shingle roofs i have cleaned i have used the CH/SH 3% augmenting mix and im not happy with the results. Three weeks ago i cleaned a brown shingle roof, last week grey shingle and today a grey shingle roof. I have noticed that the grey roofs are leaving a brown haze across the roof and the brown roof is a little darker when they dry. I did not have these results when i was just using SH....was wondering if anyone else has had this happen. Thanks.....

I use 100% CH almost exclusively and have never experienced discoloration of a composition roof. Definitely post some pics.
What percentage CH are you using and where do you get it from?

Has it rained much after it was cleaned. We've done a couple projects where there is a little brown, and if we kept spraying, all we were doing was rinsing the dead organic off. After a rain it looked perfect. Take your garden hose and rinse a small section and see what the results look like.
