Does anyone have any ideas on washing a mildewed house with nonsealed grayed out cedar shake shingles. Customer does not want shingles to be lightened by housewash mix.This house has multiple dormers and a very steep roof and many places that the mix will run directly onto shingles.I am wanting to seek ideas before declining this job,I think I'll be the third to decline. thanks

Now you've give the EPA something else to wanna reclaim, that rubber is surely going into storm drain!

Yes it is a cedar roof. This is a large house, probably $750,000 range maybe more. Keep in mind this is N.C.There are many places that the housewash mix will have to be applied by downstream or x-jet due to extreme pitch roof and distance from edge of roof. I called the owner back today with intensions of declining. She is now willing to compromise. I am gonna saturate shingles before during and after weak dilution of chems with an understanding by signature that there may be some slight lightening of shingles.I hate these roofs. I would'nt want a roof with so much maintenance and a short lifespan.Another contractor in my area cleaned one of these roofs. He had to do it from 40' lift charging a large fee. They did not want it sealed.They want the weathered look without the mold and mildew. He did it a year ago, he probably needs to follow up, I'm sure it needs cleaning again, anyway,if you live in a million dollar house here you can afford to do such.Oh yea,I know these areas could be cleaned by hand with climbing gear ,but I 'm not a monkey so that would be out of question for me.lol Beth I love this board, thanks for making it all work.
