Boy O Boy, Well I been pressure washing for some time and just started the low pressure roof cleaning. I did my research and checked all the posts on this site back to 2005 on roof cleaning. I hate asking questions like if I'am some dummy or wasting someone elses valuble time but Brotha I need some help.I bought all my equipment from BoB at P.T. and whatever else was recommened.My mix was 1 gallon of 12.5 to 3 gal. H2o and the simple cherry. The roof had mild black stains here and there on a very light color roof.The delvan applied good and I let sit for 15 min,Then rinsed with garden hose and all I took off was the cloudy marks and the dark streaks stayed. Reapplied and same deal no different.House was about 1200 Sq.Ft and I wasn't satisfied with job because of streaks still visiable. Also my partner which is a owner of a roofing company wasn't satisfied and he already has me lined up with work Whoops..LOL. If anybody could shed some light on my situation I would kiss there A**. One other thing was mentioned to me from my partner maybe the roof is to old and I said no way because I watched every video I could find on the internet from all the best companies and they clean everthing with low pressure, I love this setup if I don't get it going ASAP then I'am losing the jobs that are lined up for me..Thanks guys, Bryan.
